Research On The Transformation Of "Production-living-ecological" Land Use And Its Eco-environmental Effects In The Central Plains Urban Agglomeration

Rapid urbanization and frequent human activities have led to the transformation of land use,resulting in landscape fragmentation,ecological environment degradation,and reduced ecosystem service value.The transformation of regional “production-living-ecological” land use and its ecological effects on the rational allocation of regional land were analyzed.and ecological civilization construction is of great significance.This paper uses the Gini coefficient,land use dynamics,degree,transition matrix,gravity center migration and other models to analyze the temporal and spatial variation characteristics of the “production-living-ecological” land in the Central Plains urban agglomeration from 2000 to 2018.Using the regional ecological environment quality index（EV）and ecosystem Two methods of service value（ESV）explored the ecological and environmental effects of the transition of “production-living-ecological” land use,and analyzed the driving factors of the transition of ecological and environmental effects with the help of geographic detectors and geographic weighted regression models.research shows:（1）From 2000 to 2018,production land shrunk,living land expanded,and ecological land changed little;the comprehensive dynamic degree of land use first rose and then dropped;In terms of spatial distribution,production land is particularly balanced,living land is relatively balanced,and ecological land is unreasonable;except for other ecological land,the center of gravity migration distance is small.（2）From 2000 to 2010,the conversion of farmland production land to water and woodland ecological land was the dominant factor in the increase of EV in the study area;from 2010 to 2018,the conversion of forest land and grassland ecological land to cultivated land production land was the main reason for the reduction of EV.The ESV of production and living land in the Central Plains urban agglomeration decreased,while the ESV of ecological land increased;in 2018,the ecological and economic coordination degree of the study area was-0.0057,which was at a low level of conflict;the main factor for the increase of ESV in the study period was the conversion of cultivated land to ecological land;The main reason is that construction land encroaches on cultivated land and forest land.The two evaluation results were similar.The overall EV and ESV in the study area showed a downward trend in time and a trend of “high in the west and low in the east” in space.（3）The main factors affecting the evolution of ecological environment effects in the study area are population density,per capita fiscal expenditure,precipitation,altitude,per capita GDP and temperature;the contribution rate of natural factors to EV is greater than that of socioeconomic factors;the contribution rate to ESV On the contrary;altitude has a significant positive impact on the ecological environment,precipitation has a negative impact on EV,a positive impact on ESV,and the other four have a negative impact.（4）According to the evaluation results,put forward countermeasures and suggestions to improve the ecological environment quality and ecosystem service value of the Central Plains urban agglomeration,and promote the coordinated development of the “production-living-ecological” land and the ecological environment of the Central Plains urban agglomeration.
