摘要
土地利用主要应用遥感技术监测土地利用动态变化过程,本文应用GIS技术对牙克石市2000-2020年遥感影像进行栅格计算、掩膜提取等操作,获取了牙克石市2000、2010、2020年3个时段土地利用类型面积数据。在此基础上,运用土地利用转移矩阵分析了牙克石市土地利用的特点及变化规律。研究结果表明,2000-2020年牙克石市以林地和草地两种土地利用类型为主,合计占比约为93%,面积变化量最大的土地类型是草地,变化率变化最大的是人造地表,其中2010-2020年变化更为显著。
Research on land use cover change predominantly utilizes remote sensing technology to monitor the dynamic change process of land use.This study employed GIS technology to conduct grid-based calculations and mask extraction on remote sensing imagery of Yakeshi City for the years 2000,2010,and 2020,obtaining area data of land use types in Yakeshi City across these three time periods.Building upon this,the land use transfer matrix was used to analyze the characteristics and changes of land use in Yakeshi City.The data showed that from 2000 to 2020,woodland and grassland were the dominant land use types in Yakeshi City,accounting for approximately 93%of the total land area.Among them,grassland exhibited the largest area change,while artificial surface demonstrated the highest rate of change.The most significant transitions occurred during the 2010-2020 period.
