沙地人工林辐射平衡是森林生态系统研究的重要内容之一,也是物质转化、流动传递以及生物小气候形成的物理基础。搞清辐射平衡各分量在林中的变化规律,特别是固沙造林后引起辐射平衡的变化,对于确切估计生产潜力,分析固沙造林效益,为人工林的合理经营利用提供科学依据都具有现实意义。为此,我们于1984年5-10月在辽宁省章古台固沙林内和固定沙地上进行了辐射平衡观测。
Radiation balance of sand plantations is one of the important contents of forest ecosystem research, as well as the physical basis of material transformation, mobile transmission and the formation of biological microclimate. It is of great practical significance to find out the regularity of the variation of radiation balance components in forest, especially the change of radiation balance caused by afforestation. It is of practical significance to accurately estimate production potential, analyze benefits of sand fixation and afforestation, and provide scientific basis for rational management of plantations. For this reason, we carried out the radiation balance observation in the fixed sand in Zhanggutai, Liaoning Province from May to October 1984.
