摘要/Abstract

摘要： 本文根据1960年8—11月在热带地区海南岛树林内外的辐射平衡、热量平衡与小气候的观测,对林内外的辐射能与热能收支作了计算,分析了林内外小气候要素的分布与变化规律,得到下列初步结果:林内的辐射强度与热量交换比林外弱得多;林内得到的淨辐射主要用于土壤增热与蒸发,林外得到的淨辐射则主要用于空气增热与蒸发;林内的土壤温度与空气温度比林外低,而空气湿度则比林外高。林内的小气候是凉爽而潮湿的,林外的小气候则是炎热而干燥的。森林对改善小气候环境条件有重大的良好作用。

Abstract: During the period of August-November, 1960, observations were made to investigate the characteristics of radiation balance, heat balance, and microclimate in the forest of Hainan, Kwangtung. The results of the observations may be summarized as follows: 1) In the forest the radiation intensity and the heat exchange are much weaker than on the open ground. 2) The radiation heat is mainly spent on the soil heating and evaporation in the forest, but mainly on the air heating and evaporation on the open ground. 3) In the forest the soil and air temperatures are lower, but the humidity is higher than on the open ground. Therefore, the microclimate in the forest is cool and moist, while that on the open ground is hot and dry.
