Land use pattern change and its social and economic driving forces in Poyang lake region from 1985 to 2000 Ⅱ.driving forces analysis of land use pattern change

利用鄱阳湖地区21个县市1985和2000年的两期土地利用类型图,借助偏最小二乘回归模型定量诊断该地区土地利用格局变化的社会经济驱动力,确定了耕地、林地、草地、水域、建设用地和未利用地等6类变化的主要社会经济驱动力。

Based on two periodic land use coverages of 21 counties in 1985 and 2000, this thesis analyses social and economic driving forces of the changes of land use pattern in Poyang lake region by partial least-squares regression （PLS）. Furthermore, the major social and economic driving forces of the change of 6 land types including cultivated land, forest land, water area, built-up land and unused land are identified.
