| 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：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年后下降趋势趋于缓和。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。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及发展方向。本研究为耕地多功能研究提供了有益的方法及案例支持。 |
| 英文摘要: |
| In order to grasp the evolution and coordination characteristics of farmland multifunctionality in economically fast-developing areas, a study was conducted in the Pearl River Delta wherein the evaluation index system of farmland functions was constructed, and a mechanical model was introduced to analyze the spatial pattern of the farmland and coordination relationship among its sub-functions. The results showed that in the 15-year observation period from 2000 to 2015, the economic function, social function, and ecological function indices of farmland in the Pearl River Delta region showed a downward trend. However, after 2010, this downward trend began to slow down. There was a significant spatial difference in the degree of coordination between the various functions of farmland. The areas with high coordination were mainly in the suburbs of central cities and towns with high industrialization and modernization, while the imbalanced areas were distributed in traditional agricultural production areas. According to the degree of deviation from the coordination function of farmland, three types of quadrant were used to divide the study area. We have identified the short-term characteristics of farmland in each type of area, and put forward corresponding development suggestions. This study provides an effective method and case support for the systematic study of farmland multifunctionality. |
