基于层次分析法的广西金秀地区生态环境质量综合评价

Comprehensive Assessment of Ecological Environment Quality in Jinxiu Area Based on Analytic Hierarchy Process

  • 摘要: 2015年8月对广西金秀进行实地考察和相关参数监测,构建了生态环境质量综合评价体系,采用综合评价指数(EI)对其生态环境质量进行评价。结果表明:广西金秀地区生态环境质量综合评价指数EI=76.19,等级为良,生态环境质量较好,适宜发展生态旅游、养生旅游; 25个评价指标中影响程度在0.04以上的有13个,说明广西金秀地区环境状况处于较好水平地区,生态要素构成合理,绿化率较高; 得分较低的是水土流失率(56.00)和荒漠化面积比重(40.00),介于达标值边缘的有城镇污水处理率(62.66)、生态垃圾无害化处理率(61.33)、风寒指数年平均值(62.46),说明城市应加强水土流失和土地荒漠化的治理力度,增强城市污水和生态垃圾无害化处理能力。

     

    Abstract: The comprehensive evaluation system of ecological environment quality was constructed by field investigation and related parameters monitoring in Jinxiu, Guangxi in August 2015. The eco-environmental quality was evaluated by comprehensive evaluation index (EI). The results show that the comprehensive evaluation index of ecological environment quality in Jinxiu area of Guangxi is EI=76.19, the grade is good and the quality of ecological environment is good, which is suitable for the development of ecotourism and health tourism. There are 13 influencing factors in 25 evaluation indexes ofinfluence degree is above 0.04, indicating that the environmental condition in Jinxiu area of Guangxi is good, the ecological factors are reasonable and the greening rate is high; The soil erosion rate (56.00) and the proportion of desertification area (40.00) get the low score, the sewage treatment rate (62.66), ecological garbage treatment rate (61.33), the average annual cold index (62.46) were with the edge of the standard value, indicating that the city should strengthen the soil erosion and land desertification control efforts to enhance the urban sewage and ecological waste harmless treatment ability.
