A fishery environment is a place on which the survival and reproduction of aquatic lives rely and is the foundation of fishery development. In general, the deterioration of the environmental quality of fishery waters in China has not yet been fundamentally curbed, and dissolved inorganic nitrogen and active phosphate are still the major indicators of pollution in fishery waters. Based on analyses of the status and variation trend of the fishery environment, in this review, we clarify the main factors that affect the sustainable development of China's fishery environment, such as development of construction projects, pollution of external sources, ecological disasters, and pollution accidents; identify major environmental issues in key areas of water; propose the idea of sustainable fishery environment based on green, low-carbon, and environmentally friendly development; establish the overall development goal and the specific development goals of two stages by 2025 and 2030; and put forward suggestions and measures including strictly controlling external pollution and aquaculture self-pollution, delineating the ecological conservation redline, improving the monitoring technology system, strengthening ecological rehabilitation, and implementing innovation projects of the fishery environment in China, hoping to provide references for the protection and management of China's fishery environment.

In order to establish development goals and identify development priorities, deepening the strategic layout for ecological civilization construction in China requires an international comparison of ecological civilization construction in China and abroad. This research establishes an indices system for the international comparison of ecological civilization construction; evaluates the Group of Twenty (G20) economies based on ecological condition, environmental quality, social development, and resources utilization; and ranks the G20 economies on an ecological civilization index 2017 and on an ecological civilization construction progress rate (1990—2015). The results show that China’s level of ecological civilization construction ranks far below those of developed economies, especially in terms of environmental quality and resources utilization. However, China's construction speed ranks first among the G20 economies. This research analyzes the task hierarchies, strategic emphases, and time nodes required for China to catch up with advanced levels of ecological civilization construction.

With the rapid growth of vehicle population and vehicle miles traveled, automobile emission has become a severe issue in the metropolitan cities of China. There are policies that concentrate on the management of emission sources. However, improving the operation of the transportation system through apps on mobile devices, especially navigation apps, may have a unique role in promoting urban air quality. Real-time traveler information can not only help travelers avoid traffic congestion, but also advise them to adjust their departure time, mode, or route, or even to cancel trips. Will such changes in personal travel patterns have a significant impact in decreasing emissions? If so, to what extent will they impact urban air quality? The aim of this study is to determine how urban traffic emission is affected by the use of navigation apps. With this work, we attempt to answer the question of whether the real-time traffic information provided by navigation apps can help to improve urban air quality. Some of these findings may provide references for the formulation of urban traffic and environmental policies.

Establishing a river chief system is stipulated in the newly amended Law of the People’s Republic of China on Prevention and Control of Water Pollution, which clarifies the liability of party or administrative heads at various levels for water environment rehabilitation in their own administrative regions. In this article, we analyze the implementation effects of the river chief in China, current assessment methods, and their deficiencies, and propose two quantitative assessing methods: (1) comprehensive water quality assessment for the cross sections of rivers and lakes and (2) assessment using the pollutant load intercepting rate of sewer networks, aiming to improve the scientific rationality for effect assessment of the river chief system. With Suzhou Creek rehabilitation in Shanghai as an example, application of the comprehensive water quality assessment method was introduced. By analyzing the pollutant load intercepting rate in various provinces (autonomous regions or municipalities) in China, we find that on average 34% wastewater is still discharged into water courses in an untreated state, leading to repeated occurrence of water quality deterioration. Introducing the comprehensive water quality assessment and the pollutant load intercepting rate into the river chief assessment will effectively push the government at all levels to concentrate their human, material, and financial resources onto urban drainage network correction and the interception of pollution sources discharged into watercourses.

Through investigation and onitoring to urban landscape waters―Shichaqianhai and Roma Lake, water quality and habitat raits of typical landscape waters in Beijing were analyzed. The differences of transparency in wo lakes were discussed. The results show that, transparency of Shichaqianhai arrives at 70 cm, nd that of Roma Lake is 27 cm, which is because of different phosphorous concentration in two andscape waters. Therefore, phosphorous concentration is a key factor to keep aquatic ecosystem ealth in urban landscape waters.

Pollutants have complex source-sink relationships in water and soil environments at a catchment scale, and the transformation of pollutants in water and soil environments is primarily controlled by various water-soil interface processes. Therefore, the control of water and soil environmental pollution should consider water and soil environments as a whole, identify the real pollution source through cross-medium attribution analysis, and then control the pollution with cross-medium treatment. We first analyze the crossmedium migration processes of pollutants and the major influencing factors. Then we propose the principle and key process of crossmedium regulation, namely, cross-medium attribution identification and cross-medium treatment of water and soil environmental pollution. Moreover, we expound the important role of the processes of the following interfaces in cross-medium removal of pollutants: soil-water and slope-channel interfaces outside river channels, as well as water-sediment and water-suspended particulate matter interfaces in river channels (including water-solid interfaces in the riverbed and lateral shore hyporheic zones). Furthermore, cross-medium control of non-point source pollutants in watershed, cross-medium removal of nitrogen-containing compounds from rivers, and cross-medium removal of nitrogen and phosphorus from lakes are illustrated with practical cases. The research results can provide a scientific basis for the control and treatment of water and soil pollution.

China has the world’s largest fisheries industry that has provided a healthy and high-quality food source. Currently, guaranteeing national food security, implementing an all-encompassing approach to food, and establishing a diversified food supply system all pose a great demand for the high-quality development of China's fisheries industry. This study explores the development status and trend of fisheries in China from the aspects of fishery resources and capture, aquaculture and marine ranching, and aquatic product processing and circulation, and examines major problems through industry research and extensive discussion. Industry development goals and key measures are further proposed. Results found that the pressure on offshore capture is too high, understanding of deep-sea and polar resources is insufficient, the independent capability of technologies and equipment is inadequate, the mechanized, automatic, and intelligent levels of aquaculture are low, high-quality feed and raw materials rely heavily on imports, the basic software and hardware capabilities of the intelligent fisheries are deficient, and the aquatic product processing capacity is lagging behind. Therefore, the following key measures are proposed: conservation and restoration of offshore fishery resources, development and scientific utilization of deep-sea fishery resources, construction and application of a new technology system for green and healthy aquaculture, research and application of deep-sea aquaculture platform technologies, construction and promotion of new aquaculture models, and green processing and high-value utilization of aquatic products.Through the high-quality development of fisheries, China is expected to become advantageous in fisheries science and technology by 2035, with a total output of 8.1×107 t of aquatic products. By 2050, intelligent fisheries is expected to be realized in China, outputting 1×108 t of aquatic products.

An intelligent IEQ monitoring and feedback system: Development and applications Article
Yang Geng,Zhongchen Zhang,Juan Yu,Hongzhong Chen,Hao Zhou,Borong Lin,Weimin Zhuang
Engineering 2022, Volume 18, Issue 11, Pages 218-231 doi: 10.1016/j.eng.2021.09.017
Indoor environmental quality (IEQ) significantly affects human health and wellbeing. Therefore, continuous IEQ monitoring and feedback is of great concern in both the industrial and academic communities. However, most existing studies only focus on developing sensors that cost-effectively promote IEQ measurement while ignoring interactions between the human side and IEQ monitoring. In this study, an intelligent IEQ monitoring and feedback system (IBEM) is developed. Firstly, the IBEM hardware instrument integrates air temperature, relative humidity, CO2, particulate matter with an aerodynamic diameter no greater than 2.5 μm (PM2.5), and illuminance sensors within a small device. The accuracy of this integrated device was tested through a co-location experiment with reference sensors; the device exhibited a strong correlation with the reference sensors, with a slight deviation (R2 > 0.97 and slopes between 1.01 and 1.05). Secondly, a wireless data transmission module, a cloud storage module, and graphical user interfaces (i.e., a web platform and mobile interface) were built to establish a pathway for dataflow and interactive feedback with the occupants of the indoor environments. Thus, the IEQ parameters can be continuously monitored with a high spatiotemporal resolution, interactive feedback can be induced, and synchronous data collection on occupant satisfaction and objective environmental parameters can be realized. IBEM has been widely applied in 131 buildings in 18 cities in China, with 1188 sample locations. Among these applications, we report on the targeted IEQ diagnoses of two individual buildings and the exploration of relationships between subjective and objective IEQ data in detail here. This work demonstrates the great value of IBEM in both industrial and academic research.

Since reform and opening up to the outside world, Chinese feed industry and animal husbandry have been greatly developed. However after entering WTO and on the road of continues development,there are still various unfavorable conditions to which much attention should be paid. It is necessary to sum up experience conscientiously in the past 20 years, and proceed from national condition to quicken the pace of standardization in feed industry. The standardization of Chinese feed industry will be in line with the International standardization as soon as possible. When new products developed, the management of product quality should be tightened up. Ecological benefits must be put in the first place in the standard of environmental management.

This article discusses the regional atmospheric environmental capacity of areas in different stages of economic development, and presents the Beijing-Tianjin-Hebei (Jingjinji) region and the five northwestern provinces and autonomous regions in China as examples. The atmospheric environmental capacities for sulfur dioxide (SO2), nitrogen oxides (NOx), fine particulate matter (PM2.5), volatile organic compounds (VOCs), and ammonia (NH3) emissions were calculated for the various provinces with the constraint condition of the annual average ambient PM2.5 concentration standard (GB3095—2012), using a global chemical transport model from the Goddard Earth Observing System (GEOS-Chem). The results indicate that the total emissions of SO2, NOx, primary PM2.5, VOCs and NH3 emited from the Jingjinji and the five northwestern provinces and autonomous regions all exceed the environmental capacity.

A good water ecological environment is crucial for the sustainable development and ecological civilization of China. However, various problems remain for China’s water ecological environment, including eutrophication, pollution of drinking water sources, contamination of groundwater and coastal waters, emerging pollutants, and shortage of ecological water. In this study, we analyzed the overall situation of the water ecological environment in China, pinpointed the major challenges, and proposed the strategic thinking and several basic principles. These principles focus on improving the water ecological environment and comprehensively consider water quality improvement, water ecological protection, and water environmental risk prevention and control. Three major scientific and technological projects were proposed pertaining to (1) coordinated governance and overall restoration of mountains, rivers, forests, fields, lakes, grasses, and sand in key basins, (2) overall improvement of water environment and water ecology in the Beijing-Tianjin-Hebei Collaborative Development Area, and (3) assurance of drinking water safety in the new era. Furthermore, we proposed the following four countermeasures: (1) revising the Environmental Quality Standards for Surface Water to strengthen its leading role in the construction of water ecological civilization in China; (2) evaluating the spatial and temporal differences of nitrogen and phosphorus nutrients in China’s lakes and implementing differentiated nutrients standards; (3) assessing the current status of water ecology in China and promoting water ecology monitoring and assessment; and (4) establishing an intelligent supervision platform for drinking water safety based on big data fusion.

Strategic Study of CAE 2000, Volume 2, Issue 12, Pages 21-28
The increasing deterioration of the ecological and environmental conditions and the shortage of biological resources foreseen in the 21st century would pose a serious problem to China's economic development and retard the raising of the standard of living of its people. Mariculture, as a blue agriculture, which promises food from the sea is deemed to play a critical role in providing guarantee of safe food source to feed the 1.6 billion Chinese people in the new century. The course of development of blue agriculture would be approached through ecological and engineering aquaculture involving key strategies as： enhancing basic research as foothold while accelerating the application of high technology to attain rapid turnover of products; conducting “refine species project” aimed at producing high — quality breeds; overall restructuring of present mariculture sites to regulate their size and distribution to rationally balance the needs and demands among the various coastal mariculture industries; using modern biological and engineering technology to practise upper tidal zone and terrestrial ecological engineering aquaculture; with theoretical ecological aquaculture as basis, applying modern engineering technology to make use of offshore areas for developing the. “ facilities fisheries” ； promoting fishery products processing industry to ameliorate the nutritional intake structure of the people.
