- Abstract:
- In order to study the hydrological function of litters of the main tree species in Beijing mountainous area,the litter reserve of Quersus variabilis stand,Pinus tabulaeformis stand,Platycladus orientalis stand and Robinia pseudoacacia stand were investigated and the water-holding processes of litter were measured in two ways.(1) The thickness of the litter layer of Quersus variabilis stand,Pinus tabulaeformis stand,Platycladus orientalis stand and Robinia pseudoacacia stand was 10.5cm,4.0cm,3.8cm and 2cm.Their corresponding weight was 945g/m2,803.3g/m2,1 024.0g/m2,239.8g/m2.(2) The highest water-holding proportion of the four main tree species measured by soaking was 230.3%,165.1%,161.9% and 212.0%.During the process,water-holding proportion’s fastest growing period occurred in 0～2h,in 2～6h,the water-holding proportion grows slowly and after 6 h,the water-holding proportion hardly increases.(3) The highest water-holding proportion of the four main tree species measured by simulating rainfall was 334.3%,331.1%,415.8% and 259.9%,which are correspondingly greater than those measured by soaking.The process that the water-holding proportion changes with time by simulating rainfall method can be separated into 4 phases.In phase 1,the water-holding proportion increases rapidly;in phase 2,the proportion increases slowly;in phase 3,the water-holding proportion is getting saturated;in phase 4,the litter is totally saturated.(4) The water effective interception ability of litters can reflect the litter interception ability in natural rainfall.The ranking of four kinds of litter effective interception abilities is Pinus tabulaeformis>Platycladus orientalis>Quersus variabilis>Robinia pseudoacacia. Effective interception ability of Pinus tabulaeformis is the the greatest,which is 12.154t/hm2.According to the experiment,there are some defects of the soaking way to measure the water-holding process of litters,which can be modified by the simulating rainfall method.
