碳中和背景下南方大径材林培育问题与对策分析
Analysis on Problems and Countermeasures in Cultivation of Large-size Timber Forests in Southern China under Background of Carbon Neutrality
摘要
Abstract
Plantations are important parts of forests and play important roles in increasing carbon sinks in ter-restrial ecosystem.With strengthening of nation to forest resource protection,cultivating large-size timber for-ests has become important force to achieve strategic goal of carbon neutrality and alleviate contradiction be-tween wood supply and demand.Plantations had large areas,but mainly consisted of middle-aged and young-aged forests in southern China.How to enhance productivity of forest land and increase carbon sinks is key problem.This thesis focused on carbon sequestration function of large-size timber forests.There were problems faced by cultivation of large-size timber forests in southern China,such as unclear resources of large-size tim-ber forests and timber-forming mechanisms,unclear cultivation objectives of large-size timber forests,imper-fect directional cultivation technological system of large-size timbers,severe soil degradations and single stand structures of plantations.Management countermeasures for synergistic enhancement to efficient cultivation of large-size timber forests and carbon sequestration capacity were proposed,including existing investigation of large-size timber forest resources,scientific planning of forest lands and site selections,breeding of superior va-rieties in precious native broad-leaved tree species,precise fertilization regulation and adjustment of stand structures,which could provide basis for scientific formulation of forest ecosystem management plans.关键词
