Strategy for Synchronous Economic Development and Aqua-Environmental Protection: Realizing Quasi-non-pollution Release in a Possible Least Catchment, Starting from the Upper Reaches

Growing population and rapid economic development lead to increasing pollution loading and lowering water quality. Protection of water environments is our glory target; The key strategy is: combining management of the land-water system in catchment and realizing the quasi-non-pollution release in an as small as possible catchment area.”; developing the high technology for realizing this target in an as small as possible catchment in the lower part behind the upper input of the area.;The key techniques are: 1) Centralized processing solid and domestic wastewater at each resident point; 2) Reconstruction of wetlands in mouths of inflows into lake/reservoir; 3) Development of green agriculture in lake/reservoir by using various types of floating ecological islands and microorganism technology; 4) Construction of Physic Ecological Engineering (PEEN) at the point of drain off water from the reservoir.
