日照时长对青海湖草地能量平衡的影响
The influence of sunshine time to the energy balance on rangeland pasture in the Qinghai lake region
摘要
Abstract
Based on the data collected from Environmental gradient monitoring system locating at Xihai town of north and east Qinghai during early and mid September,the Bowen ratio method was used to calculate the sensible heat and latent heat fluxes,and this study drew the energy balance with two kinds of extreme sunlight and three conditions of sunlight.Variance Analysis and Multiple Comparisons（LSD） results showed that the energy balance was different among different sunlight conditions,indicating that it was possible to simulate solar radiation with sunlight.The influence of sunlight on energy balance was mainly reflected by the peak value,peak time,and the forms of land-atmosphere exchange.The peak value increased as the sunlight increased,and the other two should be analyzed with different case and time.关键词
