利用ArcGIS9.3的空间分析模块对深圳梧桐山风景区的生态敏感性进行单因子分析和综合评价,以期为该区的生态规划设计和生态环境保护提供科学依据。研究结果表明:不同单因子的生态敏感性分析结果基本相同;项目区内以敏感区和高敏感区的面积最大,占总面积的89%,低敏感区占10%,不敏感区仅占1%。由此可见,项目区极易受外界干扰而发生水土流失等生态环境问题,目前应以生态保护和恢复为主,尽量减少或避免开发性的人为活动。
利用ArcGIS9.3的空間分析模塊對深圳梧桐山風景區的生態敏感性進行單因子分析和綜閤評價,以期為該區的生態規劃設計和生態環境保護提供科學依據。研究結果錶明:不同單因子的生態敏感性分析結果基本相同;項目區內以敏感區和高敏感區的麵積最大,佔總麵積的89%,低敏感區佔10%,不敏感區僅佔1%。由此可見,項目區極易受外界榦擾而髮生水土流失等生態環境問題,目前應以生態保護和恢複為主,儘量減少或避免開髮性的人為活動。

In order to provide scientific basis for ecological planning&designing and environmental protection about Wutong Mountains Scenic Area in Shenzhen City , the single-factor analysis and comprehensive evaluation were con-ducted for the ecological sensitivity by using the spatial analysis module of ArcGIS 9.3.The results showed that ecologi-cal sensitivity was mostly the same by the method of different factor analysis .The zones of sensitivity level and high sensitivity level covered the largest areas in the project region , accounting for 89%of the total land areas .Lower sensi-tivity zone accounted for 10%and non-sensitivity area was only 1%of the total areas .This shows that the project re-gion is easily affected by the outside interferences that would result in the eco -environmental problems such as soil e-rosion.At the moment, high priority should be given to the ecological protection and restoration and the human inap -propriate activities should be reduced or avoided in Wutong Mountains Scenic Area .
