| 摘 要： | 基于GIS技术,在分析水土流失敏感性影响因子机理的基础上,选取降水侵蚀力、土壤质地、坡度和植被类型等作为水土流失敏感性的评价指标,对临汾市水土流失敏感性进行综合分级分区评价,并针对各区提出相应的整治对策.结果表明,临汾市水土流失敏感性区域分布较广,中度以上敏感区占研究区面积的71.1%.研究结果可以为区域生态建设和相关政策的制定提供依据.

| Abstract: | Based on GIS technology and the formation mechanisms of soil erosion, rainfall erosivity, soil texture, slope and vegetation type are as the indicators of the evaluation of soil erosion sensitivity in Linfen City. After evaluating comprehensively and zoning classification of soil erosion sensitivity. The regional distribution of soilerosion sensitivity is wider, and the moderately sensitive area exceeds 71.1% in the study area. These results provide basis for ecological construction and formul-lation of relevant policies in Linfen city. |
