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.

Problems in China’s agricultural resources and environment have become increasingly prominent, with distinct resource and environment constraints for regional agricultures. Based on regional differentiation in agricultural resource and environment characteristics, this paper divided the country into 10 first-level zones and 57 second-level zones at the county scale. The first-level zones were divided according to regional differentiation in climate and geotectonic. And the second-level zones differentiate in water resources, land resources, and environmental conditions. It analyzed the agricultural production conditions, types of resources and their different combinations, environmental production conditions, and existing problems in these zones. This study proposed the strategies of “optimizing the spatial layout of eastern, central, and western regions” and “improving Northeast China, regulating North China, and recovering South China”. Twenty-seven second-level zones, undertaking the supply of major agricultural products in China, were identified and labeled as “major agricultural developing regions in China”. The development direction and construction measures of the major agricultural developing regions in China were suggested to maintain and improve the health and sustainability of China’s agricultural production system.

With the rapid development of Chinese economy, a large number of pollutants have entered the environment of agricultural producing areas and gradually exceeded its capacity limits, leading to substantial environmental problems and pollution incidents, as well as decline in output and quality of agricultural products, which has seriously impacts on the sustainable development of China’s agricultural production and rural economy. Urbanization in Southern China started early and developed rapidly, initially at the expense of the environment. Consequently, the problem of heavy metal pollution of soil becomes prominent and is aggravated by the widespread acid rain pollution in Southern China. This paper focuses on main agricultural producing areas along the Yangtze River and systematically discusses quality conditions of various environmental elements such as water, soil, and air. In addition, it investigates the causes of pollution from the aspects of natural factors and influences of human activities, and ultimately provides prevention and control strategies for the pollution, which can be of great significance in promoting the scientific nature of environmental pollution control in the agricultural producing areas in Southern China, ensuring agricultural sustainable development, quality safety of agricultural products, and ecological environment safety, and guaranteeing people’s health and safety.

As the two largest “granaries” in China, the Northeast and Huang-Huai-Hai Plains are the main agricultural producing areas in North China, and the soil environmental risk management and control of these areas are vital to the national food security supply lifeline. This study analyzed the soil heavy metal pollution risks of main agricultural producing areas in North China by the potential ecological risk index method. The high-risk areas of Cd pollution are mainly distributed in Shenyang City in the east of Liaohe Plain, Jinzhou City and Huludao City in the south of Liaohe Plain, Shuangyashan in the Sanjiang Plain, Tianjin City in the Haihe Plain, and Xinxiang City in the southwest of the yellow river flood plain; Hg pollution high-risk areas are mainly distributed in Beijing and Tianjin of the Haihe Plain, and around the Shenyang City of the Liaohe Plain. The chemical industry, followed by the livestock and poultry industry, as well as the metal smelting and processing industry, is the major potential source of heavy metal pollution of soil in the Northeast and Huang-Huai-Hai Plains. This study proposed the “one area, one policy” pollution prevention strategy and key environmental protection projects from the aspects of environment monitoring and warning of agricultural products producing areas, clean production of industrial and mining enterprises, and comprehensive treatment of livestock and poultry pollution, which is based on local conditions and classification guidance. This study can provide important references for the strategic planning of sustainable development of the ecological environment of major agricultural producing areas in North China.

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 3, Pages 342-352 doi: 10.1631/FITEE.1800601
Recognizing and predicting the movement and intention of the wearer in control of an exoskeleton robot is very challenging. It is difficult for exoskeleton robots, which measure and drive human movements, to interact with humans. Therefore, many different types of sensors are needed. When using various sensors, a data design is needed for effective sensing. An electromyographic (EMG) signal can be used to identify intended motion before the actual movement, and the delay time can be shortened via control of the exoskeleton robot. Before using a lower limb exoskeleton to help in walking, the aim of this work is to distinguish the walking environment and gait period using various sensors, including the surface electromyography (sEMG) sensor. For this purpose, a gait experiment was performed on four subjects using the ground reaction force, human–robot interaction force, and position sensors with sEMG sensors. The purpose of this paper is to show progress with the use of sEMG when recognizing walking environments and the gait period with other sensors. For effective data design, we used a combination of sensor types, sEMG sensor locations, and sEMG features. The results obtained using an individual mechanical sensor together with sEMG showed improvement compared to the case of using an individual sensor, and the combination of sEMG and position information showed the best performance in the same number of combinations of three sensors. When four sensor combinations were used, the environment classification accuracy was 96.1%, and the gait period classification accuracy was 97.8%. Vastus medialis (VM) and gastrocnemius (GAS) were the most effective combinations of two muscle types among the five sEMG sensor locations on the legs, and the results were 74.4% in pre-heel contact (preHC) and 71.7% in pre-toe-off (preTO) for environment classification, and 68.0% for gait period classification, when using only the sEMG sensor. The two effective sEMG feature combinations were “mean absolute value (MAV), zero crossings (ZC)” and “MAV, waveform length (WL)”, and the “MAV, ZC” results were 80.0%, 77.1%, and 75.5%. These results suggest that the sEMG signal can be effectively used to control an exoskeleton robot.

Based on perception characteristic of human ear, this paper proposes synchronization multi-band maximum likelihood linear regression algorithm for robust speech recognition under noisy condition. The algorithm utilizes maximum likelihood as estimation criteria to compensate the effects of noisy condition with multi-band synchronization model and noise corruption assumption. The tests show that the proposed algorithm improves the performance of recognition system effectively.
