摘  要：
以GIS数据和统计年鉴数据为基础,采用非参数Kruskal-Wallis卡方(χ2)检验确定指标权重,基于"先分级后加权"的思路,结合RS/GIS软件对广东省惠东县的生态环境质量进行评价,研究生态环境质量评价指标体系的构建方法和权重确定方法,构建出移植性较强的生态环境质量评价模型,并以县域、乡镇行政区和栅格为评价单元进行评价。县域尺度结果表明,惠东县的生态环境质量整体较好,其生态环境质量指数(eco-environmental quality index,EQI)值达到3.6;乡镇尺度结果表明,高潭镇生态环境质量最优,其EQI值达到4.26,港口管委会生态环境质量最差,其EQI值仅为2.64;栅格尺度结果表明,西南沿海的经济发达地区的生态环境质量一般或较差,所占面积比例分别为21%和23%,东北山区的经济欠发达地区的生态环境质量优良,所占面积比例约为56%。

摘  要：
Based on the GIS data, statistical yearbook data, and the idea of "classifying indices first and weighting each index then", by adopting Kruskal-Wallis (χ2) test to confirm index weight, and in combining with RS/GIS software, this paper evaluated the eco-environmental quality of Huidong County, Guangdong Province of South China, aimed to approach the construction method of eco-environmental quality assessment index system and the method of confirming weight, and to establish an easily transplanted eco-environmental quality assessment model at county, town, and raster scales. The assessment at county scale showed that the overall eco-environmental quality of Huidong County was good, with the eco-environmental quality index (EQI) being 3.6. The assessment at town scale showed that Gaotan Town had the best eco-environmental quality (EQI=4.26), while Port Management Committee had the worst one (EQI=2.64). The assessment at raster scale showed that the eco-environmental quality of the economically developed region in southwest coast of Huidong County was fair or poor, with an area accounting for 21% or 23% of total area, respectively, while that of the economically undeveloped region in northeast mountains of Huidong County was good, with an area accounting for 56% of the total.
