| 摘 要： | 在RS与GIS支持下，以江西省新建县为研究区，采用与土地利用动态度相关的一系列时空特征指数，研究了1991、1996和2000年3个时间段上土地利用的时空动态特征.结果表明，单一土地利用动态中建设用地变化动态度最大；1991～2000年间研究区域综合土地利用动态度年均变化速度为0.165%，其中前5年变化速度比后4年快，为后者1.5倍多.1991、1996和2000年土地利用程度综合指数分别为243.68、244.08和244.87，稍高于全国平均水平23192.新建县1996～2000年各种土地利用类型总的空间转移量(转出或转入)比前一时段有所下降，土地利用变化逐渐由双向转移向单向不平衡转移转化. |

| 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 to approximately 2000 was lower than that in 1991 to approximately 1995, and the land use change was from bilateral dynamics to unilateral unbalanced dynamics. |
