Abstract: According to the biological characteristics of red bayberry, combined with years of experimental research, the climatic and ecological zoning index has been screened out and the spatial analysis models of corresponding bayberry plant indicators, longitude, latitude and altitude has been established. With the 1∶〖KG-*2〗250000 terrain data of Zhejiang province,the digital elevation model (DEM) and digital soil maps, using the recent established 10km mesoscale weather station data, ecological indicators of climate in the evaluation unit is much closer to the actual situation of Bayberry Park. The resolution of evaluation unit is 100m×100m, which greatly improved the division results in the practical production applications. The most suitable growing areas are mainly concentrated in the midwest Xianju, Linghai, Huangyan, Tiantai and other hilly areas; suitable growing areas mainly are distributed in the western 500-800m semihigh mountain; unsuitable areas, are mainly in the mountains above the altitude of 800m and islands, and other plain rice field area. It is hoped that the study will contribute to providing scientific basis for the planing of Taizhou characteristic plants and the sustainable development of bayberry industry. 
