Suitability assessment of chinese torreya based on GIS and Logistic regression

The study on the suitability assessment of Chinese torreya cultivation has the potential for providing guide information for planting and zoning. Based on GIS and Logistic regression, the authors evaluated the suitability for local Chinese torreya planting using Geoscience Database including data such as IKONOS imagery, Digital Elevation Model (DEM), soil, meteorological data and field survey data. The results showed that the acreage of the high and moderate suitable zone for Chinese torreya planting accounted for 61.7% of the total area among which the tamable acreage in the high suitable zone was 183 hectares (11.4% of the total area). The result indicated that the study area showed great potential for cultivation of Chinese torreya. The assessment provides guidance for local government in characteristic development zones of Chinese torreya planting.
