摘　　要：基于GEE(Google Earth Engine,GEE)、山东省统计年鉴、菏泽市基础地理信息数据,借助GIS空间分析功能和统计分析功能,对菏泽市2001—2022年生态环境质量状况进行综合评价、研究。结果表明:(1)菏泽市生物丰度、植被覆盖较好,但水网密度较低(均值2.867),土地胁迫呈现出逐年升高的趋势,污染负荷较高(均值为241.649)。(2)菏泽市生态环境质量状况总体处于一般等级(35≤EI<55),个别年份属于低等级的良等级(55≤EI<75)。菏泽市生态环境质量状况较为适合人类生活,但具有制约人类生活因子出现。基于此,参考国内典型案例,总结菏泽市水环境质量恶化、污染负荷严重等原因,并从生态工程修复、生态环境质量提升、深化黄河流域各城市间协作等方面提出合理策略。Based on GEE,statistical yearbook of Shandong Province and basic geographic information data of Heze,with the help of GIS spatial analysis function and statistical analysis function,the ecological environment quality of Heze from 2001 to 2022 was comprehensively evaluated.the results show that:Firstly,Heze had good biological abundance and vegetation coverage,but its water network density was low(average 2.867).Land stress showed an increasing trend year by year,and the pollution load was high(average 241.649).Secondly,the overall quality of the ecological environment in Heze was at a general level(35≤EI<55),and in some years it belongs to a low level of good grade(55≤EI<75).The quality of the ecological environment in Heze was more suitable for human life,but there were factors that restrict human life.Thirdly,referring to typical domestic cases,this study summarized the reasons for the deterioration of water environment quality and severe pollution load in Heze,and proposed reasonable countermeasures from the aspects of ecological engineering restoration,improvement of ecological environment quality,and deepening cooperation among cities in the Yellow River Basin.
