黄河水量10年调度对生态环境影响评估

摘要

应用遥感技术、水文水质数据和调查资料，从水量调度的角度对黄河主要断面的水环境质量、湿地类型及面积、水生生物多样性等方面进行分析，科学评价黄河水量10年统一调度对生态环境的影响。结果表明，黄河水量10年调度初步改善了黄河干流水环境，修复了黄河三角洲的淡水湿地，促进了河口生态系统的良性发展，在一定程度上增加入海营养盐通量，提高了近海鱼类的种类和数量。%Remote sensing technology, hydrological and water quality data , and investigation data were used to evaluate the ecological benefits of ten-year integrated water regulation of the Yellow River in terms of four aspects:the water environment, the type and area of wetlands, and the aquatic biodiversity.The results show that the integrated water regulation of the Yellow River has improved the water environment in the main stream of the river , restored the freshwater wetlands of the Yellow River Delta , promoted the sound development of estuarine ecosystems, increased the flux of nutrients into the sea to a certain extent , and improved the species diversity and quantity of offshore fish.
