A Study on the Volume and Water-Holding Properties of Litter Layer for Larix Kaempferi Forests of Eastern Region in Liaoning Province

Abstract:

A Study on the volume and water-holding properties of Litter Layer for Larix Kaempferi Forests of Eastern Region in Liaoning Province. It was showed that the vo1ume and water-holding capability of the litter layer for the 6 forest type are all indicating to the semi-decomposed litter higher than the undercomposed litter. The litter vo1ume of different forest types was ranged from 27.24 t•hm-2 to 50.00 t•hm^-2, the maximum was the cloudy slope of the half-mature forest, the minimum was the sunny slope of young forest. Different forest types’ litter layer exhibited significant different in water-holding capacity, the undecomposed litter layer displayed for the cloudy slope of the half-mature forest had maximum water-holding capacity which reached 29.74 t•hm-2, and the minimum was 14.78 t•hm-2 which came from the sunny slope of young forest. For the semi-decomposed litter layer, the maximum was the cloudy slope of the near-mature forest, which reached 29.74 t•hm-2 and the minimum was only 29.86 t•hm-2 came from the sunny slope of the young forest. By carefully analysis of experimental results and fitted relational expression of test data, we could get the equation was WA=a t b between rate of water absorbability of litter and immersion time in different forest types.
