摘　　要：结合生态环境状况指数和修正后的"压力-状态-响应"(PSR)模型,从环境质量状况以及生态安全两个角度分析出发,分别考虑自然影响以及自然、经济、社会三者的协同作用,构建了适用于描述南水北调中线主干渠沿线地区生态环境状况的综合评价指标体系。研究结果表明:评价期内环境质量状况评价等级中,只有鲁山县处于"良",安阳市"较差",其他县区均为"一般";生态安全评价方面,只有淅川县处于较安全状态,其他处于预警和中度预警状态,占研究区总面积的97.54%,中度预警占16.28%。总的来看,2014年研究区生态环境质量整体水平一般,综合生态安全形势不容乐观,需要政府部门加大对主干渠沿线输水地段人类活动的监管力度。Based on the ecological index and modified press-state-response model and beginning with environmental quality andecological security,this paper has successfully constructed the synthetic evaluation index system which can be used to evaluate the eco-environmental situation in areas along the main canal of Middle Route of South to North Transfer Project after respectivelyconsidering the natural influence and the combined influence of nature,economy and society.The results indicated that in the assessmentof environmental quality levels during the entire evaluation,only the Lushan County w as"better"and Anyang City was"worse"with others in the ordinary levels.Besides,in the ecological security Assessment,Xichuan County was the only one in relativ elysecure state while97154percent of all the study area was in the early or moderate warning states with the moderate warning areas accounting for16.28%.As a whole,eco-environment quality in-004was generally in an ordinary level,and ecological secur-ity situation was worrying,so the government should improve supervision to limit human activities in the study area.
