摘　　要：为探究区域土地利用转型下的生态环境效应演变规律,基于重庆市中心城区2000~2020年土地利用遥感监测数据,结合气泡图谱、生态贡献率、地理探测器等方法进行研究。结果表明:重庆市中心城区以生产和生活空间为主;生产和生态空间重心均位于南岸区,生活空间重心位于江北区;2000~2020年,生活空间范围不断扩张,面积增加376.42km^(2),生产空间面积减少374.70km^(2),生态空间面积总体变化不大;研究区生态环境质量水平呈现“中间低四周高”的空间分布特征,低质区以都市核心区为中心逐年向四周扩散,农业生产空间转换为工矿生产空间是导致该区域生态环境不断恶化的主要土地利用转移类型;自然和经济因素是影响研究区生态环境质量的主要因素,且经济因素的影响作用逐渐增强。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 environment 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 agricultural 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.
