摘要： 为了探讨气候变化对于广西河池市油茶气候适宜度的影响，提高气候区划的精细化程度，以期为油茶种植的合理布局提供建议。在研究广西河池市气候条件与油茶生长发育关系的基础上，筛选出油茶种植气候适宜度区划指标；同时，利用河池市及其周边21个气象站点1961—2010年的气候资料及台站地理信息、1:25000地形数据，建立区划指标的空间分析模型，按100 m×100 m细网格对区划指标进行小网格推算，采用GIS技术和专家打分法，对河池市油茶进行气候适宜度评价。结果表明：河池市绝大部分地区为油茶生长的气候最适宜区和适宜区，仅北部部分地区为油茶生长的次适宜或不适宜区；同时，受气候变化的影响，河池市境内油茶最适宜区面积有所增加，且分布区域向

Abstract: In order to discuss climate change influence on climatic suitability of Camellia in Hechi and improve the climate regionalization to provide suggestion for reasonable layout, based on the relationship between climate condition and growth of Camellia in Hechi, the climatic suitable regional indexes for Camellia planting were selected. On the basis of geographic information, climate data of 21 meteorological stations in Hechi and its nearby stations from 1961 to 2010, the climatic models were established. Different meteorological factors were interpolated on a 100 m×100 m grid and Hechi Camellia climatic suitable regionalization was finished by the technique of GIS and expert scoring method. The results showed that: except part north, most of Hechi were most suitable or suitable area, and because of the climate change, the area which was most suitable or suitable for planting Camellia would increase, and extend to north.
