根据生态因子的主导性、代表性、可计量性、可比性和易获取性原则, 选取有效灌溉面积比率、单位面积SO_2排放量、污水排污达标率、人口密度、单位面积化肥施用量、建成区比例、湿地比例、林地比例、水土流失率9个生态敏感性因子, 运用层次分析法AHP计算各因子权重, 建立生态敏感性模型, 计算武汉城市圈各地区生态敏感性评价值, 结果表明: 武汉城市圈范围内鄂东北、鄂东南低山丘陵地区生态敏感度较高; 武汉地区敏感度一般; 沿江平原地区生态敏感度较弱; 研究区生态敏感性程度整体较高

According to the leading character, representation, measurability, comparability and accessibility of ecological factor, this paper chose 9 ecological sensitivity factors, such as Irrigation Area, per Unit Area of SO2 emission, blowdown standard, population density, per unit area of fertilizer consumption, built-up area, wetland area, forest land area and water loss rate. Using AHP method to count the weight of each factor, it established ecological sensitivity model to calculate evaluation value in each area of Wuhan metropolitan. The results ...
