Temporal-spatial characteristics of land use in Xinjian County,Jiangxi Province

Abstract

Abstract: With the support of RS and GIS,and using a series of indices in characterizing the dynamics of land use,this paper studied the temporal-spatial characteristics of land use in Xinjian County,Jiangxi Province,between 1991 and 2000.The results indicated that among single land use types,the area for construction changed mostly.The annual change speed of comprehensive land dynamic index between 1991 and 1995 was 0.5 times higher than that between 1996 and 2000,and the utilization grade in 1991,1996 and 2000 was 243.7,44.1 and 244.9,respectively,being a little higher than the national average grade.The land inflow and outflow in 1996~2000 was lower than that in 1991～1995,and the land use change was from bilateral dynamics to unilateral unbalanced dynamics.

Key words: C-D effect, Reciprocal equation, Cunninghamia lanceolata
