Land-use Transformation of Production-Living-Ecology Space along Yellow River in Henan Province:Eco-environment Effect and Driving Factors
From the perspective of production-living-ecology space,this paper elaborated on the measuring the eco-environ-mental effect of multi-scale land-use transformation in eight cities and prefectural towns along the Yellow River in Henan Province during 2000-2020 by means of eco-environmental quality index and ecological contribution rate,and the geo-detec-tor model to reveal the driving factors of eco-environmental quality change was used in the meantime.Consequently,it was showed that the spatial structure in the areas along the Yellow River in Henan Province during 2000-2020 showed a land-use trend featuring overall decreases of productive and ecological areas of land,and meantime a continuous increase of land-use areas for living;the increases of various land-use areas for living and industrial/mining production,and the decline of land-use areas of agricultural production were notable in particular.Comprehensively affected by the positive and negative eco-en-vironmental circumstances during 2000-2020,the status of eco-environment quality in the study areas presented a U-shaped characteristics,i.e.,firstly decreased and then increased;the transformation of agricultural arable land into ecological land was the major reason of the improvement of ecological environment,and the spatial variation pattern spots showed an evident aggregation status,the positive contribution pattern spots distributed mainly along the River stem,but on the other hand,the pattern spots in cities of Zhengzhou and Sanmenxia showed negative contribution,and the contribution rate of Jiyuan City had experienced a change from positive to negative,while cities of Kaifeng and Luoyang had experienced a change from being negative to positive in terms of contribution rate,and the contribution rate of other cities has no qualitative change;and the night lights,the level of economic development and the population density were the main driving factors which affected the quality of ecological environment,and as to the eco-environmental effects,the influence of the interaction of factors was greater than that of single factors,and the interaction between night light and carbon oxide emission was most remarkable.It is expected that the research achievement could provide references for the overall social and economic development and eco-environmental protection in Henan Province's areas along the Yellow River.
