| 摘 要： | 基于2008年祁连山大野口关滩流域青海云杉林冠截留观测数据和青海云杉林冠各组分持水能力实验室数据,采用直接测量和回归分析方法对青海云杉林冠层持水能力进行研究.结果表明:受不同因素影响,两种方法测得的青海云杉林冠层持水能力有一定差异.回归分析法主要受林内穿透雨观测方法的影响,所得林冠层最大持水能力为0.69 mm;直接测量法主要受样地内树高、胸径、植株密度、叶面积指数等影响,所得林冠层最大持水量为0.77mm.直接测量法得到的青海云杉林冠各组分单位面积最大持水量依次为树皮(0.31 mm)＞枝(0.28 mm)＞叶(0.08 mm).

| Abstract: | By the methods of direct measurement and regression analysis, this paper estimated the water storage capacity of Picea crassifolia forest canopy in Guantan in Qilianshan Mountains, based on the observed throughfall and the laboratory experimental data about the water storage capacity of various canopy components in 2008. Due to the impacts of various factors, differences existed in the canopy water storage capacity estimated by the two methods. The regression analysis was mainly impacted by the measurement ... |
