| Abstract: | We tried to construct a comprehensive evaluation system on constructive land use intensity from the perspectives of inputs and outputs efficiency,land use structure,strength and trends of land size ,etc. Based on the reality of broadening difficulties of Longnan,with land use changing data and the second land survey data, we applied factor analysis to evaluate the intensive level of constructive land,analyzed its temporal changing trend and spatial differences,also clarified the reasons to provide reference... |
