黄河流域河南段生态环境质量时空演变及驱动因素分析OA

The planning and construction of the central economic zone and urban agglomerations pose certain challenges and pressures on the ecological environment of the Yellow River Basin(in Henan Province).It is of great significance to evaluate the spatial and temporal evolu-tion of the ecological environment quality and explore the key influencing factors to promote the sustainable development of the region.This paper used multi-category of remote sensing data and social statistical data as data sources,and used Ecological Index(EI)and Remote Sensing-based Ecological Index(RSEI)to analyze the spatial and temporal evolution of ecological environment quality and driving factors in the study area from 2010 to 2021,and analyze the trend of ecological environment quality change in each prefecture-level city.The results show that:The ecological environment quality in the study area has shown an upward and downward trend in 12 years,with overall control and relative stability;Spatially,the ecological environment quality shows the characteristics of high in the west and northwest and low in other areas.The combined effect of multiple factors on ecological environment quality is higher than the influence of any single factor,and the key factors for controlling ecological environment quality in the study area are vegetation coverage and land use.All prefecture-level cities show a trend of improving ecological environment quality.Among them,Zhengzhou City and Xinxiang City are relatively stable and the trend of improving ecological environment quality is not obvious.The trend of improvement in Jiyuan City,Luoyang City and Sanmenxia City is obvi-ous.
