重庆市渝北区土地利用/覆被变化的遥感分析

An study on the land use/cover change of Yubei District based on the Remote Sensing

利用渝北区四期的遥感影像数据,借助ENVI遥感软件,获得研究区四期的土地利用/覆被分类图,运用ARCGIS和Excel的运算功能,分析各土地利用类型的相互转化关系,并探讨其用地变化原因。结果表明:27年间,区内林地、水域和建设用地的面积有所增加;耕地、草地和未利用地面积减少;土地利用/覆被综合动态度为0. 55%,表明区域土地利用变化对该区的土地性质产生的影响还较为合理。

Using Yubei district four remote sensing image data,and with the help of a software environment remote sensing research area in the four periods of land use/cover classification figure,using ARCGIS and the operation of the Excel function,analysis of mutual transformation between different land use types,and explore its land use change. The results showed that the land area of woodland,water and building increased in 27 years. Reducing the area of cultivated land,grassland and unused land;The comprehensive dynamic attitude of land use/cover is 0.83%,indicating that the land use change has an unreasonable influence on the land nature of the area during the study period.
