摘要:
借助GIS技术手段，根据徐州地区的本底环境特征选用了7个因子，采用取最大值法对徐州地区生态敏感性及其空间分布进行了定量化分析，按生态敏感性的高低将研究区划分为5级：极高敏感区、高敏感区、中敏感区、低敏感区和非敏感区，可为研究区的开发建设和规划提供依据及参考。结果显示：高敏感区和极高敏感区占研究区面积的17.29%，中敏感区占9.85%，非敏感区和低敏感区占72.85%；表明徐州地区的生态敏感性总体上较低。
Abstract:
In this paper, with GIS technology, using maximum of the factor-overlay method, ecological sensitivity and its distribution are thoroughly analyzed by selecting regionally representative factors according to environmental background in Xuzhou. Five classes of ecological sensitivity ranging from extreme to low were generated:extreme sensitivity zone, high sensitivity zone, moderate sensitivity zone, low sensitivity zone and non-sensitivity zone, in order to provide valuable references for the development and planning. The results indicate that:17.29% of the study area was upper moderate ecological sensitivity zone, 9.85% of the study area was moderate ecological sensitivity zone and under moderate ecological sensitivity zone accounts for 72.85%, which shows that ecological sensitivity in Xuzhou is generally low.
