【摘要】：从生态需求角度从发,选择生态经济协调度、生态稀缺程度、人文发展水平作为评价指标,在对分指标进行评价的基础上,采用多指标条件判定法进行北京市生态需求程度评价,并据此划分了3个生态分区。结果显示,北京人均生态系统服务价值差距较大,从中心城区到远郊区,生态资源愈来愈稀缺;生态经济协调度中,轻度协调的区域大多位于北京北部的生态涵养区,而首都核心功能区和城市发展新区的经济协调程度多属于轻度冲突;人文发展水平从中心城区到远郊区逐渐降低;生态需求程度从中心城区到远郊区逐步降低。根据生态分区的生态需求不同,针对不同区位的特点提出了生态环境建设的建议,研究可以为区域土地资源合理规划布局与调整、生态用地配置和生态环境保护提供参考和依据。
[Abstract]:From the angle of ecological demand, we choose the degree of ecological economy coordination, the degree of ecological scarcity and the level of human development as evaluation indicators, and on the basis of evaluation of sub-indicators, The degree of ecological demand in Beijing was evaluated by using the method of multi-index condition judgment, and three ecological zones were divided according to this method. The results show that there is a large gap in the value of ecosystem services per capita in Beijing, and ecological resources are becoming more and more scarce from the central urban areas to the far suburbs. In the ecological and economic coordination degree, most of the mildly coordinated areas are located in the ecological conservation areas in the northern part of Beijing. However, the degree of economic coordination between the core functional area of the capital and the new district of urban development belongs to the mild conflict; the level of human development gradually decreases from the central urban area to the far suburban area; the ecological demand level decreases gradually from the central urban area to the far suburban area. According to the different ecological demand of ecological zone, the paper puts forward the suggestion of ecological environment construction according to the characteristics of different location. The study can plan and adjust the regional land resources reasonably. Ecological land allocation and ecological environment protection provide reference and basis.
