The Scale-Effects of Different Land Use Types on the Distribution Pattern of Park Green Space at Multiple Grid Scales—A Case Study on the Main Urban Area of Nanjing, China

Abstract

Exploring the scale-effect of different land use types on the distribution pattern of urban park green space (PGS) at multiple grid scales would inform rational allocation and efficient collaborative construction of urban development land at different scales. Selecting 300-m, 500-m, 1,000-m, and 2,000-m grid scales, the research employed Create Fishnet tool in ArcGIS and Geodetector to construct a scale-effect analysis framework that revealed the scale-effects of different land use types on the distribution pattern of PGS at multiple grid scales in the main urban area of Nanjing, China in 2006, 2012, and 2017. Main research results are: 1) the overall distribution pattern of PGS showed the evolution characteristics from polarization to advancing quality and efficiency, while the trend gradually weakened with the increase of grid scale; 2) the scale-effect of other land use types on PGS increasingly enhanced—the larger the grid scale, the more obvious the synergistic or compressive effect; 3) the interactive scale-effects of different land use types gradually enhanced—the larger the grid scale, the more significant the overall factor interaction; and 4) at the 300-m grid scale, the major interaction factors were residential, transportation, industrial/manufacturing, water area, and administration/public services, which gradually changed to residential, water area, and administration/public services up to the 2,000-m grid scale. The findings of this paper are expected to deepen the theory of the coupling between PGS and other land use types, as well as provide scientific support and a basis for efficient allocation, spatial layout optimization, and sustainable development of urban spaces.
