摘要
利用鄱阳湖地区21个县市1985和2000年的两期土地利用类型图,借助景观格局指数、土地利用动态度和土地利用转移矩阵等分析该地区15年间土地利用空间格局的变化。结果表明,耕地、林地、草地、水域、建设用地和未利用地等6种土地利用类型在空间上的分布逐渐由分散变为聚集,主导地位的土地利用类型日益突出,并逐渐向规则、连片方向发展。转移矩阵和流向分析表明,耕地主要向建设用地转移,林地主要向草地和耕地转移,草地主要向林地转移,水域主要向草地转移,建设用地则没有向其他类型转移,未利用地则主要向水域转移。
This paper analyses the spacial change characteristics of land use pattern by means of landscape pattern indices, change dynamic degree of land use and transformation matrix of land use based on two periodic land use coverages of 21 counties in Poyang lake region in 1985 and 2000. The results show that 6 land types including cultivated land, grass land, forest land, water area, built-up land and unused land become to assemble from disperse condition,while some land types prevail year by year in spacial scatter. Furthermore, all types become regular and continuous gradually. The transformation matrix and the flow direction analysis show that majority cultivated land has been converted into built-up land ,forest land has been converted into grass land and cultivated land ,grass land has been converted into forest land ,water area has been converted into grass land, unused land has been converted into water area but built-up land hasn＇t been converted into any type.
