摘　　要：以2009年至2018年的土地利用数据为基础,分析了广州市某一研究区10年间的城乡建设用地与生态用地之间的相互转移情况的定量研究,并利用标准差椭圆进行空间转移差异的研究,研究结果表明:1)研究区2009—2018年间,生态用地十分显著地向城乡建设用地进行转移,是城乡建设用地向生态用地转移量的63倍;2)城乡建设用地向生态用地转移的方向分布为东北西南向,从数量上来讲,则是西北多东南少,生态用地向城乡建设用地的转移量较少,零星分布在城区的行道旁,以及东南部山区;3)研究区在城镇化发展过程中占耕明显,10年间城市扩张土地将近一半是占用了耕地。Based on land use data from 2009 to 2018, this paper quantitatively analyzes the transfer between urban-rural construction land and ecological land in the study area which is located in Guangzhou. In this paper, we use standard deviational ellipse to study the spatiotemporal differentiation. The results show that:(1) From 2009 to 2018, lots of ecological land have been converted to urban-rural construction land. It is over 63 times of the conversion from urban-rural construction land to ecological land.(2) The direction of urban-rural construction land transferred to ecological land is from northeast to southwest, and the transferred land concentrates in the southeast zone;The area of ecological land transferred to urban-rural construction land is very less. The transferred land sporadically distributes in the sides of urban streets and southeastern mountainous region.(3) In the study area, the cultivated land is obviously occupied because of urbanization development. Almost half of the cultivated land is occupied by urban expansion land in the past decade.
