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.

Far Future

The South-to-North Water Diversion project (SNWD project) is a mega water project designed to help solve water shortages in North China. The project’s management and operation are highly influenced by runoff change induced by climate change in the water source areas. It is important to understand water availability from the source areas in the context of global warming to optimize the project’s regulation. Based on the projections of nine GCMs, the future runoff in the water source areas of the three diversion routes was simulated by using a grid-based model RCCC-WBM (Water Balance Model developed by Research Center for Climate Change). Results show that temperature will rise by about 1.5°C in the near future (2035, defined as 2026–2045) and 2.0°C in the far future (2050, defined as 2041–2060) relative to the baseline period of 1956–2000. Although GCM projections of precipitation are highly uncertain, the projected precipitation will likely increase for all three water source areas. As a result of climate change, the simulated runoff in the water source areas of the SNWD project will likely increase slightly by less than 3% relative to the baseline period for the near and far future. However, due to the large dispersion and uncertainty of GCM projections, a high degree of attention should be paid to the climate-induced risk of water supply under extreme situations, particularly for the middle route of the SNWD project.

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.

The Impact

Abstract. With dramatic changes in climate and land-cover patterns around the world, it is of great significance to evaluate the corresponding influence on runoff change as water resources have become a strategic resource. We analysed the runoff change driven by landscape change and climate variation in Hanjiang River basin, which is the water source area of the central route of the South-to-North Water Diversion Project in China. Results show that the runoff decreased greatly from 1960 to 2012 in all the six selected sub-catchments. Attribution analysis results show that reduction of precipitation contributed to the catchment runoff decrease by 39.5–64.9% and landscape change, represented by increase of the parameter in the mathematical Budyko function contributed to the runoff decrease by 34.4–63.3%, while potential evapotranspiration change had a slightly negative contribution. In addition, the contribution is spatially variable from downstream to upstream. We conclude with a qualitative description about how water availability changes under changing landscape and climate conditions, and focus on the impact of vegetation cover change.
