Abstract:

The aim was to make use of the local agroclimatic resource, optimize the industrial structure and promote the ability of disaster prevention and mitigation. Based on the 30-year climate data of this area, firstly, annual mean temperature, annually extremely lowest temperature, ≥10℃ accumulated temperature and annual precipitation were selected to be the climatic regionalization indices. Secondly, the spatiality of each regionalization index was built by using the spatial analyst and mapping tools in GIS. Furthermore, the climate applicability regionalization for tea plant in South Shaanxi was provided by using the fuzzy comprehensive evaluation method. The results indicated that the suitable regions for tea plant were those shallow mountain and hilly areas below 950 m along Hanjiang River and its tributaries. The sub-suitable regions were the surrounding hilly areas below 1200 m. Through the analysis of the climatic conditions for tea plant growth, this paper provided relevant and constructive suggestions to the production.
