| 摘 要： | 在广东省高要市活道镇马尾松林地，于晴天就地选取马尾松针叶，每隔１ ｈ１ 次用快速称重法测定其从上午８ 时到下午５ 时的蒸腾强度；与此同时，测定立地光照强度、气温、叶面温度、相对湿度、风速、气压等小气候因子的日变化－ 研究表明：马尾松针叶蒸腾强度日变化符合正弦波动，与气压相关性不显著，与相对湿度呈极显著负相关，而与光照强度、风速、叶面温度、气温均呈极显著正相关

| Abstract: | The diurnal variations of transpiration rate of masson pine ( Pinus massoniana ) leaf and microclimatic factors were explored in the sample plot selected at Town of Huodao in Gaoyao, Guangdong Province. The results showed that the diurnal variations of the transpiration rate of masson pine leaf accorded with sine wave model, and that the transpiration rate correlated very significantly and negatively with local relative humidity, while it does very significantly and positively with local light intensity, wind velocity, air temperature and the temperature of leaf surface respectively. |
