【摘要】 本文采用综合指数评价法 ,以RS/GIS技术解译的土地利用 /土地覆盖数据为信息源 ,对天山北坡经济带生态环境质量进行评价、排序及分级。结果得出 :乌鲁木齐市、乌苏市、呼图壁县生态环境质量良好 ,沙湾县、石河子市、奎屯市、玛纳斯县生态环境质量一般 ,米泉市、阜康市、克拉玛依市、昌吉市生态环境质量较差 ;良好、一般及差的县市区域面积分别占研究区面积的 39 8%、2 7 89%和 32 2 9%。这种生态环境质量分异特征主要是由自然环境条件、人类经济活动、土地利用方式决定的。更多还原

【Abstract】 Using the comprehensive evaluation index method,the paper makes an appraisal and ordination of eco-environmental quality for 11 conties in northern slope economic zone of Tian mountains.The result shows that the areas with the relatively good,moderate and relatively poor ecological environments occupy 39.82%,27.89%,and 32.29% of the total area of Xinjiang respectively.It also shows that the eco-environmental situations of Urumqi,Wusu and Hutubi are in relatively good states,the eco-environmental situations of Shawan,Shihezi,Kuitun and Manasi are in moderate states,the eco-environmental situations of Miquan,Fukang Kelamayi,and Changji are in relatively poor states.The difference of eco-environmental quality was mainly caused by natural environmental characteristics,human economic activities and the ways of land resources used.更多还原
