基于GIS的玉溪市红塔区土地利用动态变化分析
Dynamic Change Analysis of Land Use in Hongta District of Yuxi City Based on GIS

本研究借鉴了以往的理论成果和实际工作经验，对玉溪市红塔区的土地利用现状及动态变化进行分析探讨。通过利用GIS技术对2000年和2020年的土地利用现状图进行了分析，并应用土地利用动态度和土地利用转移矩阵方法，研究了该区近20年来土地利用动态的变化。研究结果表明，在研究期内，林地和耕地是红塔区最主要的土地利用类型，耕地、草地和水域面积有所减少，建设用地和林地则呈现不同程度的增加。在所有土地利用类型中，建设用地的变化率最高。
The current land use situation and dynamic changes in Hongta District of Yuxi City were analyzed and discussed based on previous theoretical findings and practical work experience. Utilizing GIS technology, the land use status maps for 2000 and 2020 were examined, and the land use dynamic trend and transfer matrix were employed to study the evolving patterns of land use in this area over the past two decades. The findings indicate that during this period, forest land and cultivated land are the primary types of land use in Hongta District, there has been a decrease in cultivated land, grassland, and water areas while construction land and forested areas have shown varying degrees of increase. Among all types of land use, construction lands have experienced the highest rate of change.
