中国城区公园绿地面积与人口数量、建设 用地面积演变的脱钩关系研究

公园绿地是满足市民“美好生活需求”的优质公共 绿色空间,并受建设用地的支撑与约束,科学认识其与人口、 建设用地相互关系是实现城市高质量发展的关键点。引入“脱 钩”理论及模型,将“公园绿地与人口、建设用地”联动,系 统分析1996—2016年三者耦合特征及整体复杂关系。研究 表明：1)公园绿地建设与人口协调关系严峻,与“以人民为 中心”导向脱节;公园绿地与建设用地处于“以土地推绿地” 的“挂钩”增长态势;2)从整体联动视角看,约1/3城市的公 园绿地与人口、建设用地整体统筹建设不协调,公园绿地发展 面临“过度依赖建设用地”困境,亟须转变成“因人口制绿, 以存量建设用地为基”建设

Decoupling Relationship of the Evolution of Urban Park Green Space Area with Population Quantity and Construction Land Area in Chinese Urban Areas

Urban park green space is the high-quality public green space to meet people''s "needs for a better life", and is supported and restrained by the construction land. Scientific understanding of its relationship with population and construction land is the key point to achieve high-quality development of cities. By introducing the "decoupling" theory and model, integrating "park green space with population, construction land" into a unified research framework, the coupling feature and overall complex relationship of the three are analyzed systematically from the national macro and structural perspective from 1996 to 2016. The research shows: 1) the coordination relationship between the park green space and population is severe, which is out of line with the "people-centered" construction orientation; park green space and construction land is in a "linked" growth trend, showing the mode of "pushing green space with land"; 2) from the perspective of overall linkage, about 1/3 of the cities'' overall construction of park green space is not in harmony with the population or construction land in China, and the construction is faced with the dilemma of "over-reliance on construction land" that needs to be transformed into the way of "developing simultaneously according to population change, based on construction land in-stock" urgently. It is an attempt to take advantage of "decoupling" research to present the coupling relationship among the urban park green space and population, construction land quantitatively and finely, from a typical perspective and typical method in the field of discipline, in order to provide scientific reference for the orderly promotion to co-ordinate and optimize the configuration of the three in the new era.
