Climate Suitability Zoning of Morinda officinalis F. C. How and Sarcandra glabra ( Thunb. % Nakai Planting in Xinfeng County Based on GIS.

Based on the meteorological data of 24 automatic stations in Xinfeng County, combined with the climatic conditions for the growth of Morinda officinalis F. C. How and Sarcandra glabra (Thunb.) Nakai, the climate suitability zoning indicators of M. ofificinalii and S. glabra in Xinfeng County were constricted by relevant statistical methods, and the climate suitability zoning indicators were divided into four grades M most suitable, suitable, sub-suitable and unsuitable. According to the results of expert scores, the relevant growth impact factors were assigned weight values. Based on geographic information system (GIS%, the climate suitability zoning of M. officinalis and S. glabba planting in Xinfeng County was carried out. The results show that most areas of Xinfeng County were suitable for planting M. officinalis and S. glabra. Among them, the most suitable planting areas of M. offinanalis were mainly distributed in most of Huilong Town, from Jiangnan Community of Fengcheng Street to Yuntianhai area of Meikeng Town, Matouwantian Village and areas to the south, and areas to the south of Zhutong Viilage, Fengcheng Street. The most suitable areas for S. glabra planting were mainly distributed in Puchang Viilage of Huilong Town, the northeast of Huangzhai Town, the south of Fengcheng Street, and the central-southern part of Matou Town.
