摘　　要：当前对区域生态环境质量评价的研究工作尚处于探索之中。在景观生态学理论与方法得到长足发展的今天,从景观生态角度对其进行综合评判有着一定的科学依据。在探讨基于景观的生态环境质量评价理论方法基础上,以新疆塔里木河中下游典型区域作为研究案例,利用选建的评价指标体系和相应评价方法综合评判了该地区2000年生态环境质量状况。研究认为,2000年该区域生态环境质量总体上处于一般状态,但有向良性化发展趋势,而恶劣的自然条件,特别是水资源贫乏是制约该区域生态环境质量良性演化的主要因素。Study on regional eco-environment quality is now in the course.As theory and method of landscape ecology has obtained quite great progress,it has scientific basis for synthetic assessing it through the angle of landscape ecology.The authors study the typical area in the lower and middle reaches of the Tarim River,based on exploring theory and method of regional eco-environment quality assessing,and synthetically assess the region's eco-environment quality.It concludes that eco-environment quality there is on general stage as a whole in 2000.However, it tends to turn better,and the major restricting factor is bad physical conditions there, especially the shortage of water resource.
