| 摘 要： | 本文在分析茶树栽培与气象条件关系和重庆市气候资源和气象灾害特点的基础上,综合确定了影响重庆市茶树区域分布差异的主要气候生态区划指标;利用Arc GIS和数字高程模型(DEM)得到重庆市80%保证率≥10℃活动积温、春旱、夏旱、伏旱和秋旱100m×100m空间分布,制作了茶树气候生态区划,将重庆市划分为:气候炎热大叶茶适宜栽培区,气候温热中小叶茶适宜、大叶茶次适宜栽培区,气候温和中小叶茶适宜栽培区,气候温凉中小叶茶次适宜栽培区和气候寒冷茶树不适宜栽培区等5种类型区,为重庆市茶树产业合理布局提供了依据。

| 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. |
