京津冀人口土地生态压力及空间调控战略研究

Land Ecological Pressure of Population and Spatial Regulation Strategy in Beijing-Tianjin-Hebei Region

以人—地平衡研究为出发点,寻找土地生态压力和人口的耦合关系,构建基于人地关系的人口土地生态压力比较指数模型,选取人口数量、人口经济密度、城市化发展水平、生态用地人口密度指标,以京津冀各市(区)土地利用变更调查数据为基础开展研究分析。结果表明:2015年京津冀地区有10个地区土地生态压力人口小于常住人口,27个地区土地生态压力人口大于常住人口;人口土地生态压力指数差异悬殊,天津中心城区高达106. 12,人口土地生态压力最大,承德市指数仅0. 11,人口土地生态压力最小,人口与土地生态压力的矛盾空间差异显著;应合理进行土地人口承载力分区,动态监测人口土地生态压力,提高土地综合承载力,制定人口调控分区政策。

Based on the study of human-land balance,this paper explores the relationship between the land ecological pressure and population,and constructs the comparative index model of land ecological pressure of population based on man-land relationship,and select four indicators,including population size,population density based on the economic output,urbanization development level,population density based on ecological land,to carry out research and analysis based on land use change survey data of different cities and districts in Beijing-Tianjin-Hebei region.The results show that:in 2015,there are 10 districts in the Beijing-Tianjin-Hebei area where the population of land ecological pressure is smaller than that of resident population,and the 27 districts have greater of land ecological pressure than that of resident population;The index of land ecological pressure of population varies greatly,the central city of Tianjin is 106.12,and the index of Chengde is only 0.11.There are significant differences in the contradiction between the population and the land ecological pressure of the different districts.We should rationally carry out the division based on the population carrying capacity,monitor the land ecological pressure of population dynamically,improve the comprehensive carrying capacity of land,and formulate the zoning policy of population regulation.
