摘要
利用1995年和2005年的Landsat5卫星遥感数据提取反映生态环境的植被覆盖度、土壤指数等因素,在软件ERDAS和Arcgis10.2支持下建立生态环境质量评价模型,评价了辉腾锡勒风电场区域1995-2005年近10a的生态环境变化。结果表明:生态环境质量"差"级面积增加了0.003%,"较差"级面积增加了0.045%,"优"级面积减少了0.82%,"良"级面积减少了6.359%,"中"级面积增加了7.130%,说明十年间辉腾锡勒风电场区域生态环境质量总体上趋于变差。
Factors such as vegetation coverage, soil index which could reflect ecological environment came from Landsat5 satellite remote sensing data in1995 and 2005, so the quality evaluation model on the ecological environment was established by the software ERDAS and Arcgisl 0.2 in order to evaluate the ecological environment change in Huitengxile Wind Farm from1995 to 2005. The results show that the ecological environment quality "bad" class area increased by 0.003%, and "poor" class area increased by 0.045%, "optimal" level area is reduced by 0.82%, "good" level area is reduced by 6.359%, and "medium" level area increased by 7.130%. It indicates that ecological environment quality in Huitengxile Wind Farm area from1995 to 2005 in general tends to be deteriorated.
