基于PLUS模型的忻州片区土地利用变化及驱动力分析

Change of Land Use and Its Driving Forces inXinzhou District Based on PLUS Model

分析太忻一体化经济区忻州片区土地利用变化及其驱动力,可以为研究区开展土地开发与管理提供科学依据。基于1990、2000、2010、2020年的4期Landsat影像数据,运用动态度、PLUS模型等方法,探究了1990-2020年土地利用的时空变化状况及其主要影响因子。结果表明:草地、耕地、林地是主要用地景观;建设用地景观面积持续增加,其他土地利用类型的景观面积均呈波动变化;土地利用景观变化速率差异明显,建设用地的变化速率最大,建设用地和未利用地动态度为正向变化;研究区土地利用景观变化的主要驱动力是社会经济因素。

The analysis of the land use changes and driving forces in the Xinzhou area of the Tai-Xin Integrated Economic Zone can provide a scientific basis for land development and management in the study area.Using four Landsat images from 1990,2000,2010,and 2020,dynamic index and PLUS models were used to explore the spatiotemporal changes in land use and its main influencing factors from 1990 to 2020.The results showed that grassland,farmland,and forestland were the main land use landscape types,while the area of construction land continued to increase and the landscape areas of other land use types fluctuated.The rate of landscape changes in land use varied significantly,with the highest rate of change observed in construction land,and the dynamic index of construction land and unused land showed a positive trend.The main driving force of land use landscape changes in the study area was socioeconomic factors.
