随着经济社会的高速发展,目前我国湖泊生态系统遭到严重破坏,导致湖泊面积严重萎缩,植被严重衰退。对洱海进行生态需水量、生态径流量的理论和评价方法的研究,在研究过程中将生态需水量分为内生态需水量和外生态需水量两部分。结果表明,不同季节适宜生态径流均可以使洱海生态环境状况达到最佳,研究结果对区域水资源的合理配置和科学制定生态方案有着重要意义。
With the rapid economic and social development, the lake ecosystem in our country has been seriously damaged, resulting in a serious decline in the area of lakes and a serious decline of vegetation. The research on the theory and evaluation methods of ecological water requirement and ecological runoff in Erhai Lake is divided into two parts: ecological water demand and external ecological water demand. The results showed that the suitable ecological runoff in different seasons can all achieve the best ecological environment in Erhai Lake. The research results are of great significance for the rational allocation of regional water resources and the scientific development of ecological solutions.
