基于RS和GIS的土地利用动态变化分析——以巴宜区为例
|
摘要
根据1998年的Landsat 5遥感影像和2018年的Landsat 8遥感影像为数据源,分别进行了遥感监督分类后得到巴宜区近20年的两期土地利用现状图,并采用了GIS空间分析技术,将定量和定性的方法相结合起来,还通过引入转移矩阵、变化动态度指数等描述土地利用空间动态变化的指标,对巴宜区的土地利用变化进行了深入的时空变化过程分析。研究表明,1998～2018年,巴宜区土地利用发生了显著的变化,其中城镇村及工矿用地和耕地呈现大幅度增长的趋势;林地和水域及水里设施用地面积也在逐年增加,尽管涨幅不太明显;只有草地和未利用地出现了减少的情况。总体而言,巴宜区的土地利用符合城镇化发展要求,未来巴宜区的生态环境和土地利用也将会是良性发展。
Based on the Landsat 5 remote sensing image in 1998 and the Landsat 8 remote sensing image in 2018 as the data sources, two land-use status maps of Nyingchi County in recent 20 years were obtained by means of remote sensing supervision and classification, and the spatial analysis technology of GIS was adopted.In this paper, the quantitative and qualitative methods were combined to analyze the spatial and temporal processes of land use change in Nyingchi city by introducing the transfer matrix, changing dynamic index and other indicators to describe the spatial dynamic change of land use.The research shows that the land use of Nyingchi County has changed significantly from 1998 to 2018, in which the urban villages, industrial and mining land and cultivated land show a large increase trend. The area of woodland and water facilities has also increased year by year, though not significantly; only grassland and unused land have decreased. Overall, the land use of Linzhi County conforms to the requirements of urbanization development, and the ecological environment and land use of Linzhi County will also be benign development in the future.
