Abstract: 【Objectives】To construct a site selection model of Forest Night Park in Guangdong-Hong Kong-Macao Greater Bay Area, and provide a feasible site selection research method for other regions in China. 【Methods】Based on night light remote sensing data (AVG), cloud-free days data (CVG), PM2.5 data, normalized Vegetation index (NDVI), land cover data and other multi-source data, the site selection model of forest dark park in Guangdong-Hong Kong-Macao Greater Bay Area was constructed. 【Results】Forest Night Park was mainly located at the intersection of Zhaoqing City, Jiangmen City, Hong Kong Special Administrative Region, Huizhou City, northeast of Guangzhou City, and Huizhou City. Medium suitable areas were concentrated in Zhaoqing City, Jiangmen City, Huizhou City, and the intersection of northeast Guangzhou City and Huizhou City; low suitable areas and unsuitable areas were concentrated in the central area of Guangdong-Hong Kong-Macao Greater Bay Area, including Foshan City, Zhongshan City, Dongguan City, Shenzhen City, Zhuhai City, Macao Special Administrative Region, and central and southern Guangzhou City. 【Conclusions】1) In the Guangdong-Hong Kong-Macao Greater Bay Area, the highly suitable construction areas were scattered, the moderate suitable areas were scattered around the highly suitable areas, and the low suitable and unsuitable areas were mainly distributed in the edges of Guangdong-Hong Kong-Macao and the areas with a high degree of urbanization in the main urban areas of each city. 2) Dark night light index, population density and NDVI index are the most influential factors in the selection of forest Dark night park in Guangdong-Hong Kong-Macao Greater Bay Area; 3) The moderately suitable construction area is mostly surrounded by the highly suitable construction area with sporadic dispersion, and the two are mostly distributed in contiguous areas. The forest night park was suitable for the construction of a wide range of regional distribution, which was conducive to combining different locations, different characteristics of culture, and different degrees of development, to build different types of forest night parks with characteristics.
