中文摘要：
近几十年来在西南高海拔山地营造了大面积的亚高山人工针叶林，该森林类型在世界上与北方森林相比具有特殊性和重要的研究价值，已经基本接近成熟林，在全球气候变化背景下该森林的天然更新潜力如何是急待回答的重要问题，其更新对全球变化的响应也是重要的研究课题。本项目围绕针叶树种的种子和幼苗这一更新的重要物质基础，研究更新的生态过程及其环境异质性（包括林窗环境、枯落物和地被层覆盖、土壤特性等）的作用，以及全球变暖、UV-B辐射增强和联合胁迫对更新的影响，包括人工林的种子雨、土壤种子库、种子萌发、幼苗存活和生长的影响、幼苗库动态特征、针叶树苗的种内竞争和与其他植物的种间竞争等，探讨现有亚高山人工针叶林的更新潜力及其影响机制和对全球变化的响应，旨在为该森林管理提供科学依据，并丰富我国具有世界意义的高海拔人工森林更新动态理论和全球变化生态学研究。
