The spatial variability and distribution of NO3- N in shallow groundwater in Huang-Huai-Hai Plain were studied by means of GPS and GIS technology. The results indicated that it did not show a spatial structure at the sampling density of 35～50 km in shallow groundwater. The spatial variability of NO3-N content belonged to high intensity. The area of NO3—N concentration over 20 mg· L-1 was about 10% of the whole Huang-Huai-Hai Plain, and was mainly distributed in the zone from Tianjin to Jinan and Xincai, Fuyang and Bengbu in the Huaihe River Basin. The area of NO3-N content in the range of 10—20 mg·L-1 was distributed in the region from Xuzhou to Lianyungang in Jiangsu Province and Weifang,in Shandong Provence, which was about 11.5% of the Huang-Huai-Hai Plain. The NO3—N concentration in the shallow groundwater was related to the groundwater depth. The NO3-N concentration was usually over 20 mg·L-1 when the groundwater level was less 3 m, while the NO3—N content was less 10 mg·L-1 when the groundwater level was over 10 m. It implied that the affecting depth of the nitrate leaching on the groundwater was less than 10 m. These results were beneficial to making decision for increasing water and fertilizer utilization efficiency and to the sustaining agricultural development in Huang-Huai-Hai Plain.

The author applies covertly and macroscopically the SPAC theory model to the water saving system of well irrigation rice in Sanjiang Plain. Several sub-systems have been taken as a whole large system, such as groundwater, machine well, sunning water pool, channel, field, environment and so on. Through applying modern building models and optimization technique, the author analyzes the mechanism and theory of each subsystem, some mathematical models about groundwater, sunning water pool, channel, water production function, water requirement and available rainfall have been built. At last, through designing the typical demonstration area, the author combines several water-saving techniques into a whole system. Thus, the goal of raising water temperature 5～15℃ , saving water 17.1% and increasing yield 700 ～1 000 kg/hm2 canbe reached.

Comparing the total pollution load into rivers in 2005 with the one in 2000, the analysis suggests that the percentage of point sources in total kept reducing year by year, and the non-point sources increased significantly, especially total phosphorus (TP) whose amount of pollution from non-point sources have already exceeded that from point sources. The total amount of pollution from non-point sources was almost equal, but its composition changed. The pollution from rural domestic sewage ranks first and the pollution from aquaculture and fields ranks second in the total amount of pollution from non-point sources. Based on the analysis of causes of non-point sources pollution, this essay gives some suggestion on the control of non-point sources pollution in plain river network of Taihu Basin.

Taking a multi dimensional perspective of economic development, carbon dioxide,industrial pollutant emission and resource consumption in the case study of Shenyang City, the resource consumption and environmental impact in the process of urban economic development and low carbon transition were analyzed. The emission reduction potential and scenario of various technologies were evaluated. The results showed that the city played a key role in global low-carbon economic construction, and emission reduction technologies in urban scale can reduce total amount of carbon emission in substantial degree. From the aspect of future development, the input of technology and economic growth pattern should be strengthened to realize economic development and total amount reduction of pollutant emission.

An energy-water coupling model is established in this paper based on long-range energy alternatives planning (LEAP)
and water evaluation and planning (WEAP), scenarios are then designed to explore the energy- and water-saving effects of different
policies in Beijing in the future and their coupling effects, and sensitivity analysis of the results is also conducted. Results show that the total energy consumption in Beijing will grow gradually by year, while water shortage is unlikely to occur. During the 13th Five-Year Plan, the total energy-saving amount owing to water-saving policies is 1.003 million tonnes of standard coal, and the total water-saving amount owing to energy-saving policies has reached 276 million cubic meters. The energy demand and water demand by residents’living, the service industry, the construction industry, and the traditional manufacturing industry are correlated, as they are critical energy-water coupling sectors. In terms of energy- and water-saving effects in different scenarios and periods, the industrial structure optimization policy shows great energy-saving potentials in the short term, while irrigation technology innovation and planting structure optimization in the agricultural sector have both good energy- and water-saving effects in the short term. A coordinated energy- and water-saving effect can be found in energy-saving scenarios in the service industry and the industrial sector. As for policies in the same sector, regulation on energy use intensity can achieve an obvious coordinated energy- and water-saving effect.

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.

The river networks in the plains of China are in low-lying terrain with mild bed slopes and weak hydrodynamics conditions. Filled with intense human activities, these areas are characterized by serious water security problems, e.g., frequent floods, poor water self-purification capabilities, and fragile water ecosystems. In this paper, it’s found that all these problems are related to hydrodynamics, and the spatiotemporal imbalance of river network hydrodynamics is identified as the common cause of these water-related problems. From this, a theory for the hydrodynamic reconstruction of plain river networks is proposed. In addition to the importance of the flow volume, this theory highlights the role of hydrodynamics and limited energy in improving the ecological water environment. The layout of water conservancy project systems (e.g., sluices and pumping stations) is optimized to fully tapping the potential integrative benefit of projects. The optimal temporal and spatial distributions of hydrodynamic patterns is reconstructed in order to meet the needs of the integrated management of complex water-related problems in river networks. On this basis, a complete theoretical method and technical system for multiscale hydrodynamic reconstruction and multi-objective hydraulic regulation in plain river networks with weak hydrodynamics is established. The principles of the integrated management of water problems in river network areas are put forward. The practical application and efficacy of the theory are demonstrated through a case study aiming to improve the water quality of the river network in the main urban area of Yangzhou City.
