Abstract
In order to clarify the water holding capacity of litters of Pinustabulaeformis forest in the northern mountains of Hebei Province,the litter stock,water holding capacity,water absorption rate and modified interception amount at Mulanweichang were studied.The result showed that:the litter amount of Pinus tabulaeformis forest at undecomposed layer and semi decomposed layer was 2.95t/hm2 and 11.58t/hm2.Water absorption rate decreased gradually with the immersion time increasing.when immersed for 4hand 6h,respectively,both undecomposed litter,and semidecomposed litter were saturated,with the maximum water holding capacity and effective interception amount of 2.28t/hm2 and 14.23t/hm2,and 1.69t/hm2 and 10.77t/hm2 respectively.
