The Impact of Litterfall on the Growth Conditions of Different Forest Stands:A Case Study of Changpoling State-Owned Forest Farm in Guiyang
摘要
Abstract
Forest litterfall is ecologically significant,and its impact on different forest types' growth is of great interest.This study,based on Guiyang's Changpoling State-owned Forest Farm,looked into how litterfall affects the growth of broad-leaved,coniferous,and mixed coniferous and broad-leaved forests.The survey across 94 forest patches revealed that from September to November,litter thick-ness of coniferous(2.73±1.49 cm)and mixed coniferous and broad-leaved forests(2.62±1.75 cm)surpassed that of broad-leaved forests(1.83±2.07 cm),signaling faster decomposition in broad-leaved forests.In these forests,rapid litter decomposition speeds up nutrient accumulation in the soil,boosting tree growth through quick nutrient release.However,in coniferous and mixed forests,litter accumulation doesn't promote growth,perhaps due to lignin and tannins inhibiting decomposition and reducing soil permeability.Overall,this study enhanced our understanding of the litterfall-forest growth relationship and offers useful insights for forest ecosystem management.关键词
