摘　　要：为探讨桂东丘陵区森林小气候效应,选择苍梧县具代表性的几种人工林作为研究对象,对其林内外的小气候进行观测。结果表明,荷木湿地松(Schima superba×Pinus elliotti)混交林内的气温、大气相对湿度与林外的差值较大;湿地松大叶栎(Pinus elliotti×Castanopsis fissa)混交林光合有效辐射最大,达1663.8μmol/(m2.s),与光合有效辐射最低的竹林相差97.4%。初步认为,林分类型和结构对林分小气候及森林防火、To explore micro-climatic effects among plantations in the hilly area of eastern Guangxi, several representative plantations have been chosen as the research object in Cangwu County, and the micro- climate inside and outside the forest has been inspected. The results show that there is significant difference of atmospheric temperature and atmospheric relative humidity between the inside and outside mixed plantation of Schirna superba and Pinus elliotti, meanwhile mixed plantation of Pinus Elliotti and Castanopsis fissa has the most photosynthetic active radiation at 1663.8μmol/m^2/s, which is 97.4% higher than that of the lowest level of bamboo plantation. It is preliminarily considered that forest type and structure have a major impact on microclimate, forest fire prevention, pest control, etc.
