Taking the forest park located on the outskirts of Fuzhou, a typical high-density city on the southeast coast, as an example, this study used ENVI-MET software to simulate and analyze the impact of different vegetation spatial configuration types on the cooling effect, aiming to propose useful strategies to improve the cooling effect of forest park vegetation. The correlation between different vegetation spatial configurations and cooling effects was systematically clarified, 18 idealized scenarios were designed, and the microclimate model ENVI-MET was used for simulation analysis. These 18 scenes represent 3 vegetation spatial configuration types with different degrees of fragmentation (blocky green space, sparse point green space, dense point green space) and 6 vegetation types (bare land, grassland, shrub, small tree + grassland, large trees + grass, large trees + shrubs). The results show that large trees are an important factor affecting the cooling effect while grass and shrubs do not cause cooling of the surrounding air due to the reason of thermal radiation accumulation. In addition, the higher the degree of fragmentation of the spatial configuration type of tree vegetation, the lower the cooling effect will be, while the effect of spatial configuration types of grassland and shrub vegetation is not significant. It is further concluded that in the process of vegetation construction and management of forest parks, attention should be paid to the cooling effect of trees, at the same time, the fragmented design of space for tree clusters should be avoided, allowing the clusters of trees to be highly concentrated.
