摘要
基于GEE平台的MODIS遥感影像,计算并分析了2000-2020年云南省生态环境质量的演变过程;利用GWR模型,分析了自然条件和社会经济对生态环境质量的影响,并对云南省生态环境质量演变的驱动力进行分析。结果表明:云南省生态环境质量总体呈现稳步增长趋势,空间上呈西高东低的分布格局;2010年为典型年份,受极端干旱影响,生态环境质量下降。2000-2020年生态环境质量全局莫兰特指数均高于0.7,云南省生态环境质量空间异质性较大,表现在高寒山区和石漠化地区,其中滇西北地区表现为高值聚类,滇东石漠化地区表现为低值聚类。生态环境质量与降水呈正相关,与人类活动呈负相关,与气温、海拔、GDP、城镇化既有正相关,亦有负相关。云南省生态环境质量呈现出复杂性,应重视滇西北高寒地区的生态系统稳定性和滇东地区的石漠化治理,保护生态环境和减少人类活动对生态环境的破坏。
Based on the MODIS data of GEE platform,the ecological environment quality of Yunnan from 2000 to 2020 was calculated and its evolution process was analyzed;the GWR model was used to analyze the im-pact of natural and social economy on the ecological environment,and we also looked into the factors that drive changes in environmental quality in Yunnan.The results show that the overall ecological environment quality of Yunnan has been steadily increasing,and the spatial distribution pattern is high in the west and low in the east;2010 is a typical year,affected by extreme drought,the overall quality of the ecological environment declined.From 2000 to 2020,the global Morant index of ecological environment quality was greater than 0.7,and the spa-tial heterogeneity of ecological environment quality in Yunnan was large,mainly in alpine mountainous areas and rocky desertification areas.The northwestern Yunnan region showed high-value clustering,and the rocky deserti-fication area in eastern Yunnan showed low-value clustering.The quality of ecological environment is positively correlated with precipitation,negatively correlated with human activities,and polarized with temperature,altitude,GDP and urbanization.The ecological environment quality of Yunnan is complex.We should pay attention to the stability of the ecosystem in the alpine region of northwest Yunnan and the control of rocky desertification in east-ern Yunnan,protect the ecological environment and reduce the damage of human activities to the ecological environment.
