【摘要】 以新疆阜康市域的生态敏感性问题为研究对象,选取土壤侵蚀、土地沙漠化以及土壤盐渍化等作为关键因子,运用ArcGIS软件分别采取单因子评价和多因子综合评价的分析方法,对研究区进行生态敏感性评价.结果表明,评价区内约99.7%的面积存在生态敏感性问题.从单因子角度看,以土地沙漠化的生态敏感性最为突出,有96.49%的区域对土地沙漠化存在着敏感性,其中高度和中度敏感性分别占46.34%和37.80%.在评价的基础上,辨别出不同生态敏感区域存在的潜在生态问题,并提出加强生态保育和生态建设的具体对策.更多还原

【Abstract】 With the eco-sensitive problems of Fukang City in Xinjiang as a research object,factors and indices,such as soil erosion,land desertification and soil salinization,are chosen to carry out single factor appraisal and integrated appraisal of eco-sensitivity with ArcGIS software.The research results show that about 99.7% of study area is sensitive to be degraded.From the viewpoint of single factors,the desertification sensitivity is the most outstanding among all the ecology sensitivity problems,about 96.49% of the area is of potential desertification sensitivity,46.34% of which is in high sensitivity and 37.80% in mid-sensitivity.On the basis of appraisal,the potential ecological problems of every sensitivity zone are distinguished and the strategic measures for environmental protection and ecological construction are put forward.更多还原
