The ecological site quality model was developed to aid in predicting the suitability of new locations for growing tree species. This model uses environmental variables to evaluate potential productivity. Into a geographic information system, 3rd Forest Resources and Land Use Inventory of Taiwan by integrated data from the climate data of Central Weather Bureau of Taiwan, the Taiwan Forest Bureau, the Council of Agriculture in Taiwan, and the United States Naval Observatory to model the distributions of elevation, slope, aspect, solar radiation, rainfall, evapotranspiration, temperature, and soil nitrogen within Taiwan. Ecological requirements of Chamaecyparis formosensis were derived from the literature and from 211 ground survey plots. Using 22,501,993 40m*40m grids within Taiwan, we modeled the requirements of C. formosensis for solar radiation, temperature, evapotranspiration, soil moisture, and soil nitrogen. We tested the model by comparing predicted sites to its known distribution of C. formosensis in Taiwan. All of the known locations of C. formosensis fell within the area predicted by the model and about 63.91% of the ESQ value are above 0.6. It showed that the model is good to evaluate the site quality for the tree species.
