摘要
土地利用强度指数能够反映土地利用变化的深度和广度,是探测人地关系的重要量化指标。以昆明市呈贡区为研究对象,运用GIS数量分析方法对研究区内各种类型土地进行数据统计分析,以土地利用动态指数和用地强度指数定量地研究土地利用变化的人类活动强度影响。结果表明:1)呈贡区的土地利用强度指数差异巨大。从时间序列看,2013—2017年用地强度指数的增加迅速,土地平均利用强度指数由206.82增长到240.81,土地利用强度增长14.11%;从空间上看,呈贡区用地强度指数呈现西高东低的态势。2)呈贡区土地利用强度主要受到房地产开发、道路建设等城市用地的影响和驱动,而受到农业生产等人类活动的影响较低。
Land use intensity index is a measurable indicator that detects the man-land relationship since it could characterize the depth and breadth of land use changes.Taking Chenggong of Kunming city as study area,this paper computes the land use changes by using GIS quantitative analysis method and statistical analysis method,and then studies how the human activities effects the land use changes based on land use intensity index and land use dynamic index.The results show that:1)the land use intensity index instudy area is very different on spatial-temporal scale.From the perspective of time series,the land use intensity index increased rapidly from 2013 to 2017,with the average value increasing from 206.82 to 240.81 and the increase is 14.11%.From the perspective of space,the land intensity index of Chenggong area presents a trend of high in the west and low in the east.2)The intensity of land use in Chenggong district is mainly influenced and driven by urban land use such as real estate development and road construction,but is less affected by human activities such as agricultural production.
