| 摘 要： | 土地利用遥感动态监测能够快速提取土地利用变化信息,更新土地利用现状图,对于土地资源合理利用、科学管理具有重要的意义.以不同时相遥感影像为主要数据源,结合其他多种数据,探讨了土地利用遥感动态监测的技术流程.以1989年和2000年石河子垦区及周边地区TM影像为基础,分析了该区域土地利用的变化趋势.研究区内的土地利用变化总体趋势是耕地(农田)面积大幅度增加,以草(林)地向耕地(农田)的转化最为显著,各种土地利用类型处在相互转化中.

| Abstract: | Dynamic monitoring of land use based on remote sensing can extract the information of land use change rapidly, update the current land use map. It is of great significance for using land resources rationally and scientific management. Taking different time image as main source of data, and combining with other data, the technology route of land use dynamic monitoring by remote sensing was studied. Based on TM image of 1989 and 2000 in Shihezi Reclamation and the surrounding areas , land-use change trend in this area was analyzed. As a result,the land-use change trend is that farmland is increasing dramatically,grass land and forest land transmitted to farmland significantly. In general, the various types land converse each other. |
