A Study on the Evolution of Ecological Environment Effect Based on"Production-Living-Ecological Spaces":A Case Study of Central Urban Area in Chongqing
To explore the evolution of ecological and environmental effects under the regional land use transformation,the study is based on the remote sensing monitoring data of land use in the central urban area of Chongqing from 2000 to 2020,combined with the methods of bubble mapping,ecological contribution rate,and geo-detector.The results show that:1.The central urban area of Chongqing is dominated by production and living spaces;the center of gravity of production and ecological spaces is located in Nan'an District,and the center of gravity of living space is located in Jiangbei District.2.From 2000 to 2020,the scope of living space continued to expand,with an increase in area of 376.42 square kilometers,whereas the area of production space decreased by 374.70 square kilometers.The area of ecological space remained unchanged.3.The level of ecological envi-ronment quality in the study area shows a spatial distribution characteristic of"low in the middle and high in the surroundings".The low-quality zones,centered around the urban core area,have been spreading outward year by year.The conversion of the a-gricultural production space into the industrial and mining production space is the main type of land-use transfer that leads to the deterioration of the ecological environment in this area.4.Natural and economic factors are the main factors affecting the quality of the ecological environment in the study area,with the impact of economic factors gradually increasing over time.
