空间分布，具有“内密外疏”的特点；方向特征表现为东北—西南走向，与城市发展方向一致；空间
分布密度呈中间高、四周低的态势，城镇组团的高密度与四周乡村组团的低密度形成强烈反差；影

| Taking the sponge type park green space in Zhanggong district of Ganzhou city as an example, with the help of
ArcGIS spatial analysis tools, the average nearest neighbor index, standard deviation ellipse and kernel density estimation
were used to identify the spatial distribution characteristics of sponge type park green space, and the explanatory power of
the main influencing factors on the spatial differentiation of sponge type park green space was measured by using geographi⁃
cal detectors. The results show that: (1) The park green space was concentrated but uneven in spatial distribution, with the
characteristics of "dense inside and sparse outside". The direction showed northeast-southwest trend, which is consistent
with the direction of urban development. The spatial distribution density was high in the middle and low in the surrounding
areas. The high density of urban clusters was in sharp contrast to the low density of surrounding rural clusters; (2) The fac⁃
tors that affect the spatial differentiation of sponge park green space include terrain slope, soil texture, land use type, runoff
status, traffic conditions and population density, of which traffic conditions had the largest impact, and the enhancement ef⁃
fect of land use type and traffic conditions was the most significant. |
