摘要：在黄土高原农牧交错带的六道沟流域,通过2年观测,研究了主要人工造林树种油松、刺槐、柠条和沙柳的冠层截留特征。结果表明:4个树种林冠截留量和林内降雨量均与大气降水量呈正相关,其中林冠截留量与大气降水量呈幂函数关系;油松林平均截留率为16.7%,刺槐林为11.6%,沙柳林为12.8%,柠条林为11.2%。模拟结果表明,修正的王彦辉模型较原模型能够更好地反映黄土高原半干旱地区典型乔灌木树种冠层截留的大小。
A 2-year investigation was made on the characteristics of canopy interception of Pinus tabulaeformis, Robinia pseudoacacia, Caragana korshinskii, and Salix psammophila plantations in the Liudaogou watershed in a farming-pastoral zone of Loess Plateau. The canopy interception and the throughfall of the four plantations had significant positive correlations with precipitation, and the canopy interception could be expressed as a power function of precipitation. The average interception of the plantations was 16.7% for P. tabulaeformis, 11.6% for R. pseudoacacia, 11.2% for C. korshinskii, and 12. 8% for S. psammophila. Simulation result showed that modified Wang＇ s model could more accurately estimate the canopy interception of the representative tree and shrub plantations in semiarid region of Loess Plateau.
