Abstract
From the angle of ecological environment balance of the river basin,the connotation of ecological environment water requirement conforming to the ecological environment of the Gansu section of the Yellow River was discussed.Based on that,a model for calculating the eco-environmental water requirement outside the river and the eco-environmental water demand model based on the water grammar method was built.The riverine basic ecological and environmental water demand,river sediment transport and sludge water demand and the eco-environmental water requirement of reservoir and lake system were calculated respectively.The results showed that the ecological environment of the Yellow River Gansu section of the total water demand was 31 billion 260 million m3,accounting for about 52％ of the annual runoff,the results far beyond the internationally recognized surface water resources reasonable development degree for the 30％ threshold,indicating that the ecological environment of the regional water demand and total watershed runoff has some conflicts in environmental protection and economic development.关键词
