基于遥感与GIS技术的苏州市土地利用动态变化研究

STUDY ON DYNAMIC CHANGE IN LAND USE IN SUZHOU BASED ON REMOTE SENSING & GIS TECHNIQUES

摘要:

利用1984年和1994年秋季1:10万TM假彩色影像,分析了苏州市10年间土地利用的动态变化。结果表明:该期间苏州市土地利用状况变化巨大,主要表现在耕地的减少以及建设用地和水产养殖用地的增加。提高耕地质量,有计划的退耕还湖,加强土地整理,合理控制建设用地规模是切实可行的土地利用对策。

Abstract:

Dynamic change in land use in Suzhou between 1984 and 1994 were studied with the aid of remote sensing & GIS techniques. The results showed that great changes took place in land use, particularly reflected by the noticeable decrease in area of cultivated land and increase in non-agricultural landuse (e.g. urbanization, highways, industry, and fishing ponds, etc.). Building up farmland quality, yielding-farmland to lakes, intensifying land arrangement, and reasonably controlling scales of landuse for construction are regarded as workable countermeasures for addressing the issue of land use in Suzhou.
