摘要 运用雨量槽和虹吸自记仪对洞庭湖水系18个主要防护林林分类型树冠截留进行了定点观测研究,建立了树冠截留随林外降水量的变化模型和树冠截留动态模型.7~8月多数林分树冠截留能力比4~6月大,且随不同时段和不同类型林分而异.不同林分树冠截留随林外降水的变化差异明显. The rainfall interception by crowns of 18 main shelter forest stands in Dongting Lake water systems is observed at fixed positions with rainfall through and siphon ombrometer.Mathematic model of rainfall interception varied With the rainfall outside forests and dynamic model of rainfall interception by crowns are established. The intercept ability of crows of most stands is stronger in July-August than in April-June, and varies with different time and stands. For different stands,their rainfall interception by crowns is varied evidently with the rainfall outside forests.
