Ecological Water Demand by River System in East Liaohe River Bas in
摘要
Abstract
The ecological water demand by the river system is the leastwater whic h maintains the natural ecological structure and the function of the river, havi ng the characteristics of spatially and the timely evolution. It includes the wa ter demand by the watercourse system (including the water transferring sand and the evaporation from water surface) and by the floodplain land. The ecological w ater demand by the water course system is 44.43% of average yearly runoff an d the ecological water demand by the floodplain land is 1.687 billion being 28 .02% of the total precipitation. The effective countermeasures must be planed to contr ol the exploitation of the water in east Liaohe river basin.关键词
