广西红锥天然林原生境自然因子调查分析

Survey on Natural Factor in Original Habitat of Castanopsis hystrix of Native Forest in Gangxi

通过调查统计广西15个红锥（Castanopsis hystrix）天然林县市的气候和土壤因子，结果表明广西红锥天然林分布的地区属南亚热带季风气候区，以红锥天然林为主的森林是我国南亚热带季雨林化常绿阔叶林的代表类型；红锥天然林分布以赤红壤、红壤林地出现较多，土壤酸碱度为微酸性（pH4．36～6．23）。根据对广西红锥天然林原生境生长发育的主要气象因子的分析结果，初步确定广西红锥的现实生态位宽度。

Climate and soil factor of Catanopsis hystrix native forest in fifteen countries were surveyed, results showed that Distribution area of Castanopsis hystrix native forest in Gangxi belongs to south subtropical seasonal wind climate, and Castanopsis hystrix native forest in the forest mainly was representative types of south subtropical seasonal rain forest and ever - green broad - leaved forest in China. Native forest Castanopsis hystrix distributed in latosolic red soil and red soil often , and alkalinity - acidity of soil appeared slightly acidity （pH4.36 - 6.23） . Based on the analyzing results of main climatic factor of growth and development of Catanopsis hystrix native forest in original habitat conditions, current ecological niche width.
