Abstract: Starting with the analysis of the man-land relationship in the course of land use,this paper explains the system of PSR conception about sustainable land-use and puts forward the index system to make a study of the sustainability of region al land use.Some methods for the assessment of sustainability are proposed as follows:weight is determined by Delphi method;effect function is used to measure the value which is contributed by every factor;and coordinative function and secondary integrated evaluation are applied to make certain the degree and phase of the regional sustainable land-use.Dynamic pattern such as evaluation-regulation-reevaluation-reregulation is put forward to make land-use sustainable.The models and indicators made up are applied to evaluate synthetically the status of land use in Yujiang county of Jiangxi Povince.The result indicates that the status of land-use in Yujiang is at the beginning of sustainable use stages and there are lots of problems on socio-economy,resources and environment,therefore countermeasure s in connection with the problems are put forward in this paper.

Key words: PSR model of land use, index system, sustainable land use, dynamic evaluation
