油茶是湖南重要的经济作物之一，为了探讨油茶气候适宜种植区域，为油茶布局提供科学依据。笔者根据油茶生长发育对气象条件的要求，以年平均气温、年日照时数及盛花期降水量3个指标作为油茶气候区划因子，针对不同气象要素采用不同的数理统计方法进行500 m×500m小网格插值，对插值后小网格的气象数据和气候区划采用等级划分法，进行湖南油茶进行精细化气候区划。结果表明：湖南绝大部分地方为油茶生长的气候最适宜区，仅洞庭湖部分地方为油茶生长的欠适宜或不适宜区；且随着近年湖南气候变暖，油茶最适宜区有所增加，发展潜力大。

Camellia is one of the important economic crops in Hunan. Considering the meteorological condition for camellia growth, the annual mean temperature, annual sunshine duration and precipitation of full-bloom stage were used as climate regionalization factor of camellia. Different meteorological factors were interpolated on a 500 m×500 m grid with different mathematic statistic method. Technique of grade division was used on the interpolated small grid data to finish refined climate regionalization for Hunan camellia. The results showed that except for part of Dongting Lake, climate condition in most of Hunan was suitable for planting camellia. Along with increasing temperature in Hunan recently, the area which was suitable for planting camellia would extend and had a big potential.
