摘　　要：本文利用2000年与2017年两个时期的卫星遥感影像,研究热带雨林区昆曼公路沿线土地利用变化特征。结果表明,研究路段10km缓冲区内建设用地与裸地总面积增加,植被与水体总面积减少,土地利用变化主要表现为建设用地与裸地以及植被覆盖的相互转化,但各类型土地利用变化幅度不大,研究区生态环境基本保持良好。利用综合土地利用动态度以及各类型土地利用动态度分析结果,发现研究路段对周边区域5km范围的土地利用变化有影响,距道路越远影响程度越小。This paper aims to study the characteristics of land use change of tropical rain forest along the Kunming-Bangkok highway using remotely sensed imagery acquired on2000and2017.The results indicated that the total area of built-up land and bare land increase within10km buffer zone around the highway,while the total area of vegetation and water body decreases.The mutual conversion of land use between built-up and bare land and vegetation were the main land transformation types.However,the variability of land change is relatively small,indicating that the ecological environment remains generally good in the study area.Analysis on the dynamic of land use demonstrates that the influences of Kunming-Bangkok highway on land use change is much greater within the5km buffer zone around the highway.In general,the further from the highway,the smaller the influence.
