衡水湖自然保护区是华北地区第一个内陆淡水湿地国家级自然保护区,具有独特的自然景观,生物资源十分丰富,但近年来区内的人类活动对其生态环境产生了严重影响。应用生态因子评分方法对保护区进行生态敏感性分析,首先将保护区划分为13个生态单元,依据原则(科学性、代表性、可行性以及定量性等原则)并结合实际选择出评价因子,然后进行各生态单元的自然因素生态敏感性分析和社会因素生态敏感性分析,在此基础上进行保护区的生态敏感性综合分析。依据计算结果,将保护区中各生态单元划分为最敏感区、一般敏感区和弱敏感区3个等级,明确了生态敏感性的区域分异特征,为该区今后合理的产业布局、区域生态环境保护提供了科学依据。
衡水湖自然保護區是華北地區第一箇內陸淡水濕地國傢級自然保護區,具有獨特的自然景觀,生物資源十分豐富,但近年來區內的人類活動對其生態環境產生瞭嚴重影響。應用生態因子評分方法對保護區進行生態敏感性分析,首先將保護區劃分為13箇生態單元,依據原則(科學性、代錶性、可行性以及定量性等原則)併結閤實際選擇齣評價因子,然後進行各生態單元的自然因素生態敏感性分析和社會因素生態敏感性分析,在此基礎上進行保護區的生態敏感性綜閤分析。依據計算結果,將保護區中各生態單元劃分為最敏感區、一般敏感區和弱敏感區3箇等級,明確瞭生態敏感性的區域分異特徵,為該區今後閤理的產業佈跼、區域生態環境保護提供瞭科學依據。

Heng-shui Lake Nature Reserve, the first inland freshwater wetland national nature reserve of north China, has unique natural landscape and rich biological resources; However, human activities within the area have imposed serious impact on the ecological environment in recent years. Using eco-scoring methods to ecological sen- sitivity analysis, first, we divided the reserve into 13 ecological units and selected ecological sensitivity evaluation factors on the ground of principles (scientific, representative, and feasible, as well as quantitative, et al. ) and Jfacts. Then, based on ecological sensitivity analysis on natural factors and social factors, we conducted a comprehensive analysis of the ecological sensitivity. According to the calculation results, the ecological units in the district are divided into three regions of different degrees of sensitivity : the best sensitive area, the generally sensitive area and the weaker sensitive area. And the spatial distribution of ecological sensitivity is characterized, thus providing scientific foundation for rational industry distribution and regional eco-environment protection in future.
