基于RS与GIS的福建省土地利用动态变化研究

Dynamic Change of Land-use in Fujian Based on RS and GIS

利用1996年和2001年2期1∶10万TM假彩色影像资料,采用人机交互目视解译方法,分析了福建省5年的土地利用动态特征。结果表明,土地利用的变化主要表现在林地、耕地的减少和草地、城镇建设用地的增加;5年间,城镇建设用地的年变化率最大,因此,加强林地保护,提高耕地质量,合理控制建设用地规模是切实可行的土地利用对策。

Dynamic change of land - use in Fujian between 1996 and 2001 were studied with the aid of remote sensing ＆ GIS techniques. The data were extracted from LANDSAT TM image. The results showed that great changes took place in land use, particularly reflected by the noticeable decrease in area of forest land and cultivated land, and increase in grass land and construction land. In 5 years, the change rate of the construction land was most high. Intensifying forest protection, building up farmland quality, and reasonably controlling scales of land use for construction were regarded as workable countermeasures for addressing the issue of land use in Fujian.
