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(pH 4.36~6.23)。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。 Through the investigation and statistics of the climate and soil factors of 15 natural Castanopsis hystrix natural forest counties in Guangxi, the results show that the natural coniferous natural forest in Guangxi is distributed in the subtropical monsoon climate zone, and the natural forest dominated by red cone is South China Tropical monsoon forest and evergreen broad-leaved forest. The red cone natural forest distributes in red soil and the red soil forest appears more. The soil pH is slightly acidic (pH 4.36-6.23). Based on the analysis of the main meteorological factors of the growth and development of natural coniferous natural forests in Guangxi, the realistic niche breadth of Guangxi red cones was initially determined.
