摘要
运用RS、GIS等技术方法,解译覆盖1990、2000和2013年中山市的TM基础遥感影像数据,进一步分析其土地利用时空变化特征.结果表明,1990-2013年中山市的土地利用类型在结构、数量和变化率上发生巨大变化,建设用地需求激增,耕地资源骤减.耕地下降达40.96%,主要转出到建设用地和基塘用地,草地和林地变化不大.空间分布上,增加的建设用地主要由耕地和基塘用地转入,集中在靠近江门市区、佛山市顺德区的西北部地区、中山市城区周边地区以及靠近珠海市区的南部地区;西北部基塘用地的几何中心也逐步朝中西部、南部及东部转移,并在南朗镇沿海处出现大面积的鱼塘.人口增长、社会经济发展和政府政策等驱动是影响中山市土地利用变化的主要因素.
Abstract
The TM remote sensing image data in 1990,2000 and 2013 were analyzed by some technical methods like RS and GIS,and the temporal and spatial characteristics of land use were analyzed.The results showed that the land use type of Zhongshan City had changed greatly in the structure,quantity and rate of change from 1990 to 2013.The demand for construction land had increased and the cultivated land resources had plummeted.cultivated land fell to 40.96%,mainly transferred to the construction land and pond land.Grass and woodland change lightly.In the spatial distribution,the increase in the construction of land mainly by the arable land and pond land,concentrated in the vicinity of Jiangmen City,northwest region Shunde District of Foshan City,the surrounding areas of Zhongshan City and near the southern part of Zhuhai City.Geometric centers in the northwestern pond land are gradually moving towards the central,western and eastern parts,and large areas of fish ponds appear at the coastal town of Nanglang.Population growth,socio-economic development and government policy drive was the main factor affecting the land use change in Zhongshan City.
