【Abstract】 Baiyang Lake is one of the inland lakes in North China. It has a good aquatic ecosystem and comprehensively developed fishery, reed-growing, farming and shipping. The unstable water level, especially the drying up of the lake may crushingly destroy the aquatic biotic resources and result in the change from an aquatic ecosystem into a terrestrial one. Artificially controlling and stabilizing the water level of Baiyang Lake, actively restroing and developing aquatic biotic resources and keeping the good circulation of the aquatic ecosystem are the strategic measures to delay or avoid the clogging up of the lake and to make the most of the ecological, economic and social benefits.更多还原
