摘要
利用福建省2002-2007年土地利用变更调查数据,采用改进的TOPSIS方法对福建省土地利用结构合理性、土地利用动态度以及土地利用结构合理性和土地利用类型相关性进行了分析,结果表明：①2002-2007年期间福建省土地利用结构合理度总体较高,在时间上的变化呈波动趋势,2003年土地利用合理性最高;②耕地面积减少量最大,居民点工矿面积增加量最大,年变化速率最快的是交通运输用地;③不同土地利用类型的变化对土地利用结构的合理性影响不同。
The rationality of land use structure,land use dynamic degree and the correlation between the rationality of land use structure and land use type were assessed by using the improved TOPSIS method in accordance with the changing data of land use from 2002~2007 in Fujian Province.The results show that： ① The rationality of land use structure during 2002~2007 in Fujian Province was generally high,appearing the wave trend following the time changes,that achieved highest score in 2003;② The area for farmland decreased most,while the area for settlement and industry and mining increased most,and the area for transportation changed the fast annually;③The change of different kinds of land use type had different effect on the rationality of land use structure.
