摘    要: 在总结国内外对生态敏感性研究的基础上,应用生态因子评分方法和GIS技术对广州市城市生态系统进行敏感性区划,将广州市划分为最敏感区、敏感区、弱敏感区和非敏感区4个等级,其中北部林区多属于最敏感区,大部分园地属于敏感区,和水源相邻的耕地属于弱敏感区,其他分散的林地和未利用土地则属于非敏感区.并提出了相应的保护对策,为该市今后产业合理布局,区域生态环境保护提供科学依据.

关 键 词:城市生态系统  生态敏感性评价  保护对策

Abstract:Based on the summary of internal and external ecosensitivity studies and using of eco-factors-valuing method and GIS technique, the spatial distribution of the Guangzhou City ecosystem ecosensitivity has been assessed; and the distribution is classified into four different grades (best sensitivity region, sensitivity region, weaker sensitivity region, non-sensitivity region). As a result, the north forest belong to best sensitivity region, most of garden plot belong to sensitivity region, the farm near to the waterhead belong to weaker sensitivity region, the dispersive forest and unutilized soil belong to non-sensitivity region. And the corresponding protecting policies are put forward, thus providing scientific foundation for rational urban industry distribution and regional eco-environment protection in future.
Keywords:urban ecosystem  ecosensitivity assessment  protection policy
