| 摘 要： | 要通过中国省域违法占用耕地的时空特征分析,得知1999-2007年中国违法占用耕地均值的空间布局总体较为离散,局部地区表现出集聚态势；运用空间计量分析方法,对1999-2007年间中国各省域违法占用耕地的空间效应研究表明,中国大陆31个雀域的违法占用耕地在地理空间上存在显著的正自相关关系,表现出了某些省域违法占用耕地的相似性在空间上趋于集聚现象,1999-2007年中国违法占用耕地的省域空间集聚近似呈现“N”字型波动变化的态势.中国违法占用耕地省域之间正的空间效应正在增强,中国省域违法占用耕地存在地理空间的邻近效应.

| Abstract: | Through analyzing temporal and spatial features of illegal occupied cultivated land in Chinese provinces,the paper showed that spatial distribution of Chinese illegally occupied cultivated land was generally discrete but in some areas it agglomerated from 1999 to 2007.The spatial measurement was used to analyze the spatial effect of illegally occupied cultivated land in Chinese provinces from 1999 to 2007.The study indicated that the illegally occupied cultivated land in 31 provinces in Chinese mainland had... |
