| 为了掌握经济快速发展地区耕地多功能的演化规律及其耦合协调特征，以珠江三角洲为研究区，构建耕地功能评价指标体系，引入力学平衡模型分析了各时段耕地多功能的空间格局及其各子功能间耦合协调关系。结果表明，（1）2000-2015年珠三角地区耕地经济功能、社会功能及生态功能整体呈下降的时序趋势，但2010年后下降趋势开始缓和。（2）耕地各功能间协调度空间差异明显。高值区主要分布在农业产业化、现代化水平较高的中心城镇的郊区，失调区分布在传统农业生产地区。从协调度演变来看，总体上珠三角地区耕地多功能的协调性呈良性发展态势。（3）根据耕地功能协调度偏离方向不同划分了三类象限区，明确各类型区耕地功能短板并提出了相应发展建议。 |

| n order to grasp the evolution and coordination characteristics of farmland multi-functionality in economically fast developing areas, an study was conducted in The Pearl River Delta, the evaluation index system of farmland functions was constructed, and the mechanical model was introduced to analyze the spatial pattern of farmland and coordination relationship among its sub-functions. The results show that: 1) Between 2000 and 2015, the economic function, social function and ecological function of farmland in the Pearl River Delta region showed a downward trend overall, but the downward trend began to ease after 2010. 2) There is a significant spatial difference in the degree of coordination between the various functions of farmland. The areas with high coordination are mainly in the suburbs of central cities and towns with high industrialization and modernization, while the imbalanced areas are distributed in traditional agricultural production areas.3) From the analysis of the evolution characteristics of farmland functions coordination, the coordination of farmland multi-functionality in the Pearl River Delta region shows a good development trend. 3) According to the degree of deviation of the coordination function of farmland, three types of quadrants are divided. We have identified the short-term characteristics of farmland in each type of area and put forward corresponding development suggestions. |
