摘要
文章采用地理探测器;以建制市作为样本单元;探究106国道沿线样带1996—2016年建成区绿地率的空间分异格局;进一步分析“社会—自然”作用机理.研究表明:1)样带市域建成区绿地率总体差异明显;呈“南北高中间低”的空间格局;市域间差异逐渐减小;年均增幅呈“中部快两头慢”的规律;2)经济实力和自然作用力等复杂动力相互作用是造成差异的主要成因;其中人均GDP、园林城市、人均建成区面积是主要驱动因素;3)经济发展水平是造成建成区绿地率区域差异的决定性因素;国家政策进一步强化空间分异性;自然条件具有双向影响力;框定样带初期市域建成区绿地率空间分布基本格局;支撑前期发展;制约后期建设.该研究以期为科学制定区域城市绿地建设政策提供理论依据;进一步协调自然与社会经济对城市绿地的影响作用.
This paper takes the designated cities as the sample unit to study the spatial differentiation pattern of green space rate in the built areas along 106 National Highway from 1996 to 2016 by using the geogdetector study method,and further analyses the working mechanism behind the "social-natural"action. The results show that: 1) There is generally a obvious difference of green space rate in built areas of the transect zone,showing a spatial pattern of"low in the section between North and South"; the difference between cities decreases gradually,and the annual average growth rate is "fast at both ends and slow in the middle section"; 2) The complex dynamic interaction between economic strength and natural forces is the main cause of the difference,among which GDP per capita,garden city and built area per capita are the main driving factors; and 3) The level of economic development is the decisive factor to the regional difference of green space rate of the urban built-up areas; national policy further enhances spatial differentiation; natural conditions have two-way influence,framing the basic spatial distribution pattern of green space rate in the initial built areas of the sample section,supporting the early-phrase development and restricting the later construction. This study is aimed to provide a theoretical basis for the science-based policy of regional urban green space construction,and further coordinate the impact of natural factors and social economy on urban green space.
