大果藤黄地理分布与气候因子的关系

Relation between geographical distribution of Garcinia pedunculata Roxb.and climatic factors

大果藤黄是一种喜欢温暖而有一定的耐寒性,喜欢潮湿而不耐旱的亚高温植物。利用温暖指数WI、寒冷指数CI、湿度指数HI和其他气候指标,分析大果藤黄地理分布与气候因子的关系结果表明,影响大果藤黄分布的主要限制指标包括极端最高温、7月平均温、平均相对湿度、年平均气温、蒸发量、温暖指数、平均日照时数和1月平均温。其中,热量条件包括年平均气温和温暖指数,是对大果藤黄地理分布影响最大的主导因子;湿度因子包括年降水量和平均相对湿度,是对大果藤黄地理分布影响较大的第二主导因子。

Garcinia peduculata Roxb is a subtropical plant with a preference for moisture and warmth.The relation between Garcinia pedunculata Roxb. geographical distribution and climatic factors was analyzed with Kira＇s warmth index and coldness index, Xu＇s humidity index and other climate indexes.The results revealed that extremely highest temperature,july average temperature, average relative humidity,annual average tempearture,evaporation,warmth index,the average sunshine hours and january average temperature were the basic limiting factors,which affect the distribution of Garcinia pedunculata roxb. Heat condition was the dominant factor, humidity factor is the second leading factor.
