Abstract Reasonable eco-compensation standards are conducive to increasing the enthusiasm of residents in the water source area of the water diversion project for ecological environmental protection and maintenance and for improving the water quality security of the water receiving area. In this paper, a comparative analysis of calculation mechanisms, formulas, and results of 7 types of eco-compensation standard methods for the Middle Route Project of the South-to-North Water Diversion Project in China is conducted. The research shows that the calculated results for the 7 types of methods differ greatly and considers that the cost and ecological service value methods are appropriate. Using this as the basic method to consider introducing market value of water resources, internal income of water source area, and government financial support for method improvement, the results show that the improved methods can reduce the gap between the per capita income of the water source area and the reference area, increase the satisfaction of both the water receiving area and the water source area, and provide support for overall socioeconomic development.

Beijing is located in a semiarid region, and water shortage is a common problem in the city. Along with the rapid increase in water demand, due to fast socioeconomic development and an increase in population, a shortage of water resources and a deterioration of the water environment have become obstacles to sustainable socioeconomic development in Beijing. In the long run, sustainable water resources management, water conservation, and completion of the south to north water diversion project will solve the problem. This paper introduces the water resources situation in Beijing; analyzes future water demand; and discusses the actions of water saving, nontraditional water resources exploitation, wetland construction, and water environment protection. The paper also explains the importance of the south to north water diversion project and the general layout of the water supply strategy, water distribution system, and methods to efficiently use the diverted water in Beijing.Key words: water resources, water supply, water saving, water recycling, water diversion.

The quantitative estimation of non-point source (NPS) pollution provides the scientific basis for sustainability in ecologically sensitive regions. This study combined the export coefficient model and Revised Universal Soil Loss Equation to estimate the NPS nitrogen (NPS-N) and NPS phosphorus (NPS-P) loads and then evaluated their relationship with Primary Industrial Output Value (PIOV) in the water source area of the middle route of South-to-North Water Diversion Project (SNWDP) for 2000–2015. The estimated results show that: (1) dissolved nitrogen (DN) load increased 0.55%, and dissolved phosphorus (DP) load decreased 4.60% during the 15 years. Annual loads of adsorbed nitrogen (AN) and adsorbed phosphorus (AP) increased significantly before 2005 and then decreased after 2005. Compared with 2000, AN and AP loads in 2015 significantly decreased by 32.72% and 30.81%, respectively. Hanzhong Basin and Ankang Basin are key areas for controlling dissolved pollution, and southern and northern regions are key areas for adsorbed pollution. (2) From 2000 to 2005, NPS pollutants and PIOV showed weak decoupling status. By 2015, NPS pollutants had strong decoupling from PIOV in most counties. (3) Land use has been the main source of NPS-N and NPS-P pollution, accounting for about 75% of NPS-N and 50% of NPS-P based on the average value over the study period. In the future, various measures—such as returning cropland to forest and reducing the number of livestock—could be adopted to reduce the risk of NPS pollution. NPS pollution caused by livestock was grown over the past 15 years and had not yet been effectively controlled, which still needs to be urgently addressed. Collecting ground monitoring data and revising parameters are effective means to improve the accuracy of simulation, which deserve further study. The results will also provide scientific support for sustainable development in similar regions.

The South–to–North Water Diversion project provides water mainly for Henan and Hebei province , Beijing and Tianjin city . So the ecological environment protection in the water source areas is very important. But the ecological environment of water source areas of the middle route project is damaged becsuse a large amount of fertilizer and pesticide are used in the field, the pollution is heavy, and some lakes are turned into fields at some area. The systematic ecological circulation circles have not been established. This paper puts forward the countermeasures and methods of establishing the ecological circulation circle in the water rource areas of the middle route project after it illustrates the importance of establishing the ecological circulation circle in the water source areas , and analyzes the problems of the ecological circulation circle in the water source areas.
