基于GIS与RS的珠江口两岸耕地流转空间格局分析
Spatial Pattern Analysis of Cultivated Land Conversion in the Coastal Area of Pearl River Estuary Based on GIS and RS
【摘要】 在GIS与RS技术的支持下,对珠江口两岸耕地流转的空间格局进行了定量分析。结果表明,在城市扩张压力下,耕地面积急剧减少,其中1988~1995年是耕地面积减少数量最主要的时期;其他的土地利用类型也在向耕地转变,水域和林地是转化为耕地的主要土地利用类型;珠江口东岸耕地流转更为严重,70%以上耕地流转为建设用地。
【Abstract】 The spatial pattern of cultivated land conversion in the Coastal Area of Pearl River Estuary based on RS and GIS technology was quantitatively analyzed.The results showed that the cultivated land area reduced rapidly under the pressure of urban expansion,and the main period of cultivated land reduced was from 1988 to 1995.Other types of land,especially waters and the forest land,were converted to the cultivated land.On the east of the Coastal Area of Pearl River Estuary,the conversion of cultivated land was more serious and more than 70 percent of the cultivated land was converted to construction sites.
