| 摘 要： | 基于广东省农用地分等调查核算成果，建立了珠江三角洲地区农用地分等单元标准粮理论单产与自然等指数、标准粮可实现单产与利用等指数的函数关系，测算该地区粮食理论生产能力和单产、可实现生产能力和单产以及实际生产能力和单产，摸清珠三角不同区域耕地产能总量及其空间分布状况。结果表明，珠三角耕地理论产能的利用潜力平均为4498．83kg／hm^2，东莞市最高，深圳市最低；可实现产能的利用潜力平均为4575．76kg／hm^2，深圳市最高，广州市最低。

| Abstract: | Based on Guangdong agricultural land classification, some function relations were established between theoretic unit production of standard crop and natural quality of farmland graduation, and between feasible unit production of standard crop and utilization index in Zhujing Delta. This paper calculates theoretic productive capacity, feasible productive capacity, actual productive capacity of farmland and unit pro- duction of specified crops and analyzes the productivity and spatial distribution of farmland in different areas of Zhujiang Delta. The results showed that the average utilization potentiality of farmland theoretic production in Zhujiang Delta is 4 498.83 kg/hm^2, Dongguan is the highest and Shenzhen is the lowest; the average utilization potentiality of reliable production is 4 575.76 kg/hm^2, Shenzhen is the highest and Guang- zou is the lowest. |
