| 摘 要： | 以北京市为例,在解析识别耕地功能表征因子的基础上,分别对北京13个区县(不包括中心城区)耕地的生产、生态、社会功能进行评价,利用GIS反映多功能的空间分布形态,并通过信息熵模型对耕地多功能与社会经济的空间相关性进行测算,讨论各区县耕地多功能与其经济社会发展的互动关系以及发展阶段的协调模式。本文旨在揭示北京市耕地多功能在社会经济影响下的空间分异特征,为制定科学的耕地多功能利用布局方案提供理论依据。研究结果表明:北京市各区县经济社会发展水平与耕地多功能的空间相关性较强,具有明显的空间分异特征;此外在经济与政策的共同驱动下,多功能与经济的组合模式随着经济发展经历高生产-中社会-低生态的正三角形态向低生产-中社会-高生态的倒三角形态演变的一般过程。

| Abstract: | Taking Beijing as an example we evaluated the productive, ecological and social functions of arable land in thirteen counties using characterization factors and excluding urban core areas. We used the AHP method to evaluate the productive, ecological and social functions of arable land;economic and social development levels were evaluated the same way. Based on an administrative map of Beijing and evaluation of multifunction arable land in thirteen counties, we explored spatial features using GIS technology. We used joint entropy modeling to estimate spatial correlation for multifunction arable land and the social economy. Last, we divided productive, ecological, social functions and economic level into low, middle and high and classified different combinations of stages into five types of coordination model to analyze evolution characteristics and trends. We aimed to reveal the manifest characteristics of multifunction arable land and the impact of socio-economics. The results showed that economic and social development, and multifunction arable land, in our focal counties have strong spatial correlation;counties with high multifunction are the economically developed regions. In addition, with development of the economy, the coordination model of the county changed from a low level economy accompanied by a triangle pattern of high productive-middle social-low ecology function to a high level economy accompanied by an inverted triangle pattern of low productive-middle social-high ecology function. Judging from time series, these counties are trending toward positive succession whereby productive function increases and ecological function decreases gradually. |
