| 摘 要： | 在借鉴文献的基础上,结合珠三角地区实际情况,构建耕地多功能评价指标体系,运用加权求和评分法计算得出耕地各类功能指数。结果表明:2005—2013年珠三角各城市耕地总功能整体表现稳定,空间差异表现为中心城市的功能等级较低,外围城市的功能等级较高,耕地资源禀赋和经济发展水平是影响耕地总功能的最主要因素;耕地的各项子功能整体表现较为稳定,体现出较为明显的空间差异;耕地资源禀赋、经济发展水平、人口及城市化水平、要素投入水平和政策因素等是影响各项子功能的主要因素。

| Abstract: | Based on the reference literature,according to the realistic condition of Pearl River Delta,an eval-uation index system on arable land multi-functions was established,then weight sum method was used to calculate each kind of arable land function indexes. Results indicated that:(1)From 2005 to 2013,the total function of ara-ble land in nine cities of Pearl River Delta maintained in a stable state,the spatial differences showed that total function in nuclear cities was lower than that in peripheral cities,cultivated land resource endowment and economic development level were the major impact factors. (2)Each subfunction of arable land showed a stable trend,and had obvious spatial differences. Cultivated land resource endowment,economic development level,population and urbanization level,elements of input level and policy factors were the obvious factors which had impact on each subfunction of arable land. |
