Abstract:
Based on the analysis of the climate resources and meteorological disaster characteristics in Chongqing city, this paper focus on the study of the relationship between tea cultivation and meteorological conditions and finally obtains the major climatic and ecological regionalization indicators that generate the difference in regional distribution of tea plant in Chongqing.Through using Arc GIS and Digital Elevation Model (DEM), the 100m×100 m spatial distribution of Chongqing 80% guaranteed rate ≥10℃ accumulated temperature, spring drought summer drought, summer and autumn drought are geraneted and so as to make the climatic and ecological regionalization of tea. As a result, the Chongqing city will be divided into five categories of tea growing areas: suitable hot growing area of broad-leaf tea, suitable warm growing area of middle-small-leaf tea but less-suitable growing area of broad-leaf tea, suitable warm growing area of middle-small-leaf tea, less-suitable cool growing area of middle-small-leaf tea, unsuitable cold growing area of tea tree, which can provide a scientific basis for the reasonable layout of the tea industry in Chongqing.
