摘要:
基于GIS和RS技术生成土地利用变化图谱，对图谱单元分析，更为简单直观地显示分析土地利用格局变化。以2000年和2005年重庆市长寿区TM遥感数据为基础数据，对遥感数据进行预处理，并对其进行遥感解译，最终利用解译结果合成土地利用变化图谱，通过分析图谱单元得到重庆市长寿地区的土地利用格局变化。研究表明：（1）耕地始终是主要土地利用类型，但由于城镇化建设，耕地面积有所减少；（2）居民点和交通用地面积增加明显，人多地少的问题愈加明显；（3）退耕还林工程的实施效果在靠近山区的部分比较显著，但仍然有少数天然林砍伐现象的存在。
Abstract:
This land use map is based on GIS and RS technology,on the map unit analysis,a more simple and intuitive display of the analysis of land use change.Based on the 2000 and 2005 TM of remote sensing data of Changshou District,preprocessing the remote sensing data,and interpreting remote sensing,the final results of interpretation were used to generate maps of land use change.The change of land use pattern in Changshou was obtained by analyzing the map unit.The results show:(1) Farmland is the main type of land use all the time,but the area of cultivated land decreased rapidly because of extension of town and township;(2) The residential area and traffic area increased greatly.The conflic between fast growth of population and limited farm land is very significant;(3) The effect of returning farmland to forest is obvious in the part of mountain.But there is minority phenomenon of deforestation.
