| 摘 要： | 土地利用/土地覆盖是生态环境系统的组成部分,它的变化是区域生态环境演变的直接反映和结果,它是区域生态环境演变的一个重要因素。运用RS/GIS技术,采用土地利用类型覆盖率作为评价因子,参考国际和国内各省的土地利用类型覆盖率制定评价标准,对伊犁河谷生态环境进行模糊综合评价。得出伊犁河谷生态环境质量属"优"的面积覆盖率占伊犁河谷总面积的73.2%;生态环境质量为"良"的县市面积覆盖率占伊犁河谷的26.3%。伊犁河谷生态环境总体较好,局部较差。伊犁河谷各县市的耕地面积覆盖率、建设用地覆盖率和草地面积覆盖率是各县市生态环境状况差异的主要原因。该方法与其他方法比较,所得的评价结果比较一致,结论符合实际状况,且有计算简便快捷等优点,方法可行,具有一定的可靠性和理论价值。

| Abstract: | Land use and land cover are parts of eco-environment system and important factors of eco-environmental evolvement,so as to their transformation are the direct response and results to region ecological changes.According to the evaluation standards of landuse coverage rate reference to overseas and inland coverage rate,a fuzzy comprehension evaluation to the eco-environment of Ili river valley are carried out by taking the landuse coverage rate as estimate factors and using RS/GIS techniques.The results show ... |
