摘要：

为了科学、合理地利用陕南秦巴山区农业气候资源，进一步优化产业结构，达到趋利避害、防灾减灾的目的，本文根据陕南秦巴山区近30年气候资料，采用年平均气温、年极端最低气温、≥10℃积温、年降水量4个因子作为陕南茶树气候适宜性区划指标；利用GIS空间分析及制图功能，在实现区划指标空间化基础上，采用模糊综合评判方法，对陕南秦巴山区茶树气候生态适宜性进行区划。结果表明适宜区主要分布于秦巴山区沿汉江及其支流沿岸海拔950 m以下的浅山丘陵地带，次适宜区主要分布在次适宜区周边海拔1200 m以下浅山区，就各适宜区茶树生长气候条件优劣进行评述，并提出了有针对性的生产建议。

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.
