基于“三生”功能的晋中市土地利用转型时空特征及驱动因素分析

Analysis on the spatiotemporal characteristics and driving factors of land use transition in Jinzhong based on“production-living-ecological”functions

以“三生”功能为视角,定量分析山西省晋中市土地利用转型特征及其驱动因素,探究市域土地利用转型规律。运用地学信息图谱、多指标综合指数法探究晋中市2000—2020年土地利用转型图谱特征和隐性形态时空格局特征,运用地理探测器分析转型驱动因素。结果表明,2000—2020年晋中市处于高强度的土地利用转型状态。2000—2010年图谱单元变化最为明显的是农业生产用地向绿地生态用地和农村生活用地的转换,2010—2020年图谱单元类型以农业生产用地与绿地生态用地之间的相互转换为主。晋中市各区县转型指数呈持续上升趋势,2020年在晋中市东北部形成“Z”字形空间集聚特征。榆次区、平遥县与其周边的寿阳县、太谷区、祁县和榆社县共同形成“T”字形高速发展区。土地利用转型是自然环境、交通区位、社会经济共同作用的结果。自然环境和交通区位对土地利用显性转型的驱动力较大,交通区位和社会经济因子对隐性转型的驱动力较大。

The characteristics of land use transition and its driving factors in Jinzhong City,Shanxi Province from the perspective of the“Production-Living-Ecological”functions were quantitatively analyzed,to explore the laws of land use transition in the city were explored.The geo-information atlas and multi-indicator comprehensive index methods were used to explore the geographic features of land use transition and the spatial-temporal patterns features of recessive forms in Jinzhong City from 2000 to 2020,and the geodetector was used to analyze the drivers of transition.The results showed that during the study period,Jinzhong City was in a state of high�intensity land use transition,and the most significant change in atlas units from 2000 to 2010 was the conversion of agricultural production land to greenland ecological land and rural living land.From 2010 to 2020,the main type of atlas unit was the conversion between agricultural production land and greenland ecological land.The transition index of all districts and counties in Jinzhong City showed a continuous upward trend,forming a“Z”shaped spatial agglomeration in the northeastern part of Jinzhong in 2020.Yuci District,Pingyao County,and its surrounding Shouyang County,Taigu District,Qi County,and Yushe County together formed a“T”shaped high-speed development area.The transition of land use was the result of the combined effects of the natural environment,transport location,and social economy.The natural environment and transportation location had a greater driving force for the explicit transition of land use,while transportation location and socio-economic factors had a greater driving force for the recessive transition.
