摘　　要：针对重点生态功能区的生态重要性,利用地形、地貌、气候等数据和生态环境状况,运用层次分析方法,选择荔波县为研究区,在GIS空间叠加技术的支持下对其进行生态敏感性评价。结果表明:荔波生态敏感性较高,其中不敏感区域面积最小,仅占8.76%,轻度和中度敏感地区面积总和约占区域总面积1/2,二者比例分别为25.63%、26.13%,高度敏感地区占区域总面积的21.15%;极度敏感区面积较大,占总面积的18.33%;荔波生态敏感性在很大程度上与石漠化相关。总体上,研究区内生态环境虽然良好,但在敏感性高的区域易产生生态环境问题,是生态环境恢复与保护的重点地区。We investigated the ecological importance of significant eco-function areas, using the initial information on terrain data and ecological environment, etc, applying to Analytic Hierarchy Process （AHP）, with the support of GIS space technology to evaluate ecological sensitivity of Libo County. The results showed that Libo was high ecological sensitivity of the area, in which the smallest non-sensitive regions brinh only 8.76%; slight and moderate sensitive area being about 1/2, in which the percentages were 25.63% and 26.13% respectively. Highly sensitive areas accounted for 21.15% of the total area, and the extremely sensitive area was larger, accounting for 18.33%. Libo ecological sensitivity was largely associated with the rocky desertification. As a whole, it was a good ecological environment of the study area, but high sensitive areas had ecological environment problems easily, and they are the key area of ecological environment recovery and protection.
