摘要
近自然林既是一种森林经营模式,也是一种森林林分状态.近年来,京津冀平原地区主要城市开展了大规模的植树造林,但真正与近自然林理念相契合的造林工程或森林经营模式仍在少数.基于京津冀平原地区自然环境特点和森林植被的历史变迁,总结近年来平原造林工程存在的问题和经验,分析北京市相关造林技术导则中关于营造林方面的内容,对该地区近自然林营造的树种选择、林龄结构和群落组配等方面进行深入探索,为近自然林的设计和营造方法提供技术指导.
Near-natural forest is not only a forest management model,but also a forest stand state.In recent years,large-scale afforestation has been carried out in major cities in the Beijing-Tianjin-Hebei plain area,but there are still few afforestation projects or forest management models that really correspond to the concept of near-natural forest.This paper studies the natural environment characteristics and forest vegetation historical changes of Beijing-Tianjin-Hebei Plain,summarizes the existing problems and experiences of plain afforestation project in recent years,and analyzes the relevant contents of Beijing afforestation technical guidelines.On this basis,the selection of tree species,age structure,and plant community arrangement of close-to-nature forest construction in Beijing-Tianjin-Hebei Plain were explored to provide technical guidance for the design and construction methods ofnear-natural forest.
