| 摘 要： | 为研究西南桦人工林在不同气候条件下的生长表现,调查了广西田林县老山林场、八渡乡西南桦试验林,通过单因素方差分析、多重比较,研究了不同海拔的气候与西南桦生长表现的关系。结果表明,西南桦生长量与气候条件密切相关,在一定海拔范围内,温湿度指数越大,生长量越大。在调查地点,西南桦适合在海拔400~950 m的气候条件种植,林分生长达到或超过丰产林标准;海拔过低或过高的气候条件对西南桦生长不利。

| Abstract: | In order to study growth performance of Betula alnoides under the different climatic conditions,a survey has been conducted at Laoshan Forestry Station in Tianlin County,the experimental forest of Betula alnoides in Badu Village,Guangxi Province,by means of analysis of variance(ANOVA) and multiple comparisons.The results showed that the growth of Betula alnoides is closely related to the climatic conditions.Within a certain range of altitudes,the greater the index of temperature and humidity,the better the ... |
