西藏扎木地区高山松松脂产量与温、湿度的关系

Relationship between rosin output of Pinus densata and air temperature and humidity at Zhamu region of Tibet

初步探讨了西藏扎木地区高山松产脂过程随温、湿度变化的泌脂规律．回归分析结果表明，在适宜温度下，相对湿度是影响该地高山松松脂日产量的主要气候生态因子，水分供给对于松脂产量有着极其重要的意义．

The patterns of rosin secretion from Pinus densata at Zhamu region of Tibet are studied under different air temperature and humidity.Regression analysis shows that under appropriate air temperature,relative air humidity is the main factor affecting the daily output of rosin from P.densata.Water supply is of importance to the rosin output.
