摘    要:瀛湖是南水北调丹江口水库重要的水源涵养区,承担着丹江口水库60%的供水量,又是沿线乡镇和安康市城区饮用水水源地。在充分调查的基础上,采用综合健康指数法对1986—2012年之间瀛湖的水生态系统健康状况进行了评估,结果表明,1986—2005年,瀛湖水生态系统健康指数呈逐渐下降趋势,健康状态由健康降至一般病态;2005—2012年之间,瀛湖水生态系统健康指数总体呈上升趋势,健康状态除2010年为一般病态外,其余均为亚健康状态。

关 键 词:瀛湖  熵权  综合指数法  水生态系统健康

Abstract:Yinghu is the water conservation area of Dan Jiang Kou reservoir in South-to-North water transfer project.It supplies over 60% of water supply of Dan Jiang Kou reservoir and it is the drinking water source for An Kang city and surrounding towns. Based on the sufficient investigation,during the period of 1986 to 2012, the water ecosystem health of the Yinghu was established by using entropy weight comprehensive health index method. The results showed that during the period of 1986 to 2005 the comprehensive health index of the water ecological system of Yinghu revealed a declined trend and the aquatic health level dropped from health to morbidity. During the period of 2005 to 2012 the comprehensive health index of the water ecological system of Yinghu revealed a rising trend and the aquatic health level was sub-health except that was morbidity in 2010.
Keywords:Yinghu  entropy weight  comprehensive index method  water ecosystem health
