广东省生态环境时空演化分析及美丽广东建设建议

通过深入解析广东省生态环境的时空分异特征,为广东省生态环境保护工作持续走在全国前列、为其他地区提供示范样板和经验提供依据。采用统计分析、GIS空间分析等方法分析1990—2021年广东省污染物排放情况、环境质量情况和生态状况,结果显示:广东省污染物产生量逐年增加,比如工业固体废物;得益于近年来持续深入打好污染防治攻坚战和“三废”处理能力的增强,排放量表现出增加—下降的过程;水环境质量整体较好,部分地市有待提高;大气环境质量东西两翼较好,中部城市有待提升;森林等自然资源条件处于国内中等偏上水平,投入管理有待加强。

Through in-depth analysis of the temporal and spatial differentiation of ecological environment in Guangdong Province,it provides a basis for the ecological environmental protection work in Guangdong Province to continue to walk in the forefront of the country and provide a model and experience for other regions.Statistical analysis,GIS spatial analysis and other methods were used to analyze the pollutant discharge,environmental quality and ecological conditions in Guangdong Province from 1990 to 2021.The results showed that the production of pollutants in Guangdong Province increased year by year,such as industrial solid waste;thanks to the continuous and in-depth fight against pollution prevention and control in recent years and the enhancement of the"three wastes"treatment capacity,emissions showed a process of increase-decline;the overall water environment quality is good,and some cities need to be improved;the air environment quality is better in the east and west,and needs to be strengthened in the central city;the condition of natural resources such as forest is above the medium level in China,but the input management needs to be strengthened.
