| 摘 要： | 依据鄱阳湖地区1949~2002年耕地面积和社会经济统计数据,分析耕地面积变化趋势。结果表明,在近53年里,鄱阳湖地区耕地面积经历了快速增长(1949~1957年)、大幅减少(1957~1978年)、缓慢减少(1978~1995年)、波动变化(1995~1999年)和迅速减少(1999 ~2002年)五个阶段。而在空间变化上,不同县市的变化率相差很大,通过聚类分析将20个县市分为四类。

| Abstract: | Based on the statistical data of cultivated land and social and economic factors from 1949 to 2002 in Poyang Lake Region, this paper discusses the trend of cultivated land change. During the past 53 years, five variable stages have been undergone in the variation tendency, during which the area of cultivated land increased fast (1949~1957), reduced widerange (1957~1978), decreased slowly, fluctuated and changed (1995~1999) and reduced rapidly (1999~2002).Four clusters describe the spatial variation of the cultivated land according to the cluster analysis in 20 counties. |
