摘要:
川西高原地处我国第一、二阶梯过渡带，生态类型复杂，生态敏感性评价对川西高原环境保护决策、全国生态敏感性区划有重要意义。采用多因子综合分析法，选取水力侵蚀敏感性、冻融侵蚀敏感性、沙漠化敏感性、石漠化敏感性指标作为川西高原生态敏感性评价的依据，对川西高原进行精细化的生态敏感性评价。结果表明：（1）川西高原水力侵蚀中度及以上敏感区面积约为14 312.62 km2，主要分布在凉山州中部、甘孜州南部；（2）冻融侵蚀中度及以上敏感区总面积约为46 250.68 km2，主要分布于甘孜州西北部、阿坝州南部；（3）沙漠化中度及以上敏感区面积约为1 956.49 km2，主要分布在甘孜州西北部、凉山州中部；（4）石漠化极度、高度、中度敏感区总面积约为765.88 km2，主要分布于阿坝州南部、甘孜州东缘、西南。这些敏感性等级较高的地区，也是生态环境恶化的地区，应引起足够重视，及时采取有效措施预防、制止生态环境恶化。
Abstract:
Chuanxi Plateau is located in transition zone from the first to the second step, its ecological type is complex and its ecological sensitivity evaluation is crucial to environmental protection decision of Sichuan Province and ecological function zoning of China. Using the multifactor comprehensive analysis method, the sensitivity of water erosion, freeze-thaw erosion, desertification sensitivity, sensitivity of rocky desertification were selected as the basis of ecological sensitivity evaluation of the West Sichuan Plateau. The results showed that: (1) moderately water erosion sensitive area in Chuanxi Plateau is 14 312.62 km2, mainly distributes in central Liangshan State, south of Ganzi State; (2) moderate and above freezing thawing erosion sensitive area in Chuanxi Plateau is 46 250.68 km2，mainly distributes in northwest of Ganzi State，south of Aba state; (3) moderate desertification sensitive area in Chuanxi Plateau is 1 956.49 km2，mainly distributes in northwest of Ganzi State，central Liangshan State; (4) moderate and above stony desertification sensitive area in Chuanxi Plateau is 765.88 km2，mainly distributes in south of Aba State，east and southwest of Ganzi State. These high sensitivity areas are also the ecological deterioration areas，should be paid enough attention and effective measures should be taken to prevent environmental degradation.
