摘要： 广西是世界上金花茶物种资源最丰富的地区。为了探讨金花茶气候适宜种植区域，为金花茶种植布局提供科学依据，根据金花茶对生态气候条件的需求，分析确定了影响广西金花茶分布的气候区划指标，利用广西90个气象台站1961—2010年气候资料及台站地理信息数据，采用GIS技术对区划指标进行小网格推算，得出了广西不同地理背景下1 km×l km网格点上有关的气候要素值，通过GIS的空间分析和多层复合等方法，对广西金花茶进行气候生态适宜区的划分。结果表明：金花茶生长的适宜区和次适宜区分布在广西南部，其中适宜区主要分布在广西南部沿海一带，左、右江河谷部分区域，以及桂东南和桂西南海拔较低的地区；不适宜区分布在广西北部以及南部海拔较高的山区；并对各适宜区提出了有针对性的种植建议。

Abstract: Guangxi is a Camellia nitidissima species most resource-rich area in the world. According to the requirements of growth and development for climate conditions of Camellia nitidissima, the author analyzed and identified the indexes of climate division for Camellia nitidissima planting in Guangxi. Using the climate data from 1961 to 2010 and the geographical information data of 90 weather stations in Guanxi, division indexes were worked out on small grid of 1 km×1 km by GIS, which gave out different values under different geographical conditions. By the function of spatial an analysis and multi-overlapping method of GIS, the climatic regionalization of suitable regions for Camellia nitidissima planting was done, and assessment and suggestions were put forward as a scientific basis for Camellia nitidissima promote the cultivation and production and its optimized distribution in Guangxi. The results showed that: the fitted regions were southern coastal areas, part of the area of the Zoujiang and Youjiang River Valley, and lower elevation areas of the southeast and southwest. The sub-fitted regions were the other southern region. The unfitted regions were northern region, and the southern elevations in the mountains. Suggestions were provided relevant and constructive to the production for Camellia nitidissima.
