摘要
中国长江流域有着丰富的林木资源,包含极高水平的物种多样性、特有性和遗传多样性。根据考古证据,在旧石器和新石器时代长江文明早期的孕育与发展中,林木在食物、能源、工具、建筑和舟船中的应用起到了关键作用。现在,长江流域和珠江流域逐渐成为国内木材供给的热点地区。面对木材供给总量不足和大径级木材结构性短缺问题,长江流域林木资源将是未来国内木材安全的重要保障。这使得林木种质资源的保护更加迫切。针对长江流域林木种质资源保护存在的家底不清和保存体系不完善问题,我们应尽快完成林木种质资源的全面调查和重要树种的多样性分析;完善原地、异地和设施保存相结合的保存体系。
The Yangtze River Basin in China has abundant forest resources, including high species diversity, endemism, and genetic diversity. According to archaeological evidence, forest resources played a substantial role during the formation and development of Yangtze River Civilization in the Paleolithic and Neolithic Age. Food, energy, tools, architecture, and boats were all derived from forest resources. At present, the Yangtze River Basin and Pearl River Basin have become the domestic center of wood supply in China. Faced with insufficient timber supply and shortages of large diameter timber, responsible management of the Yangtze River Basin forest resources is crucial to guarantee domestic timber security in the future. Understanding the status of remaining resources and creating an improved preservation system are needed to effectively conserve forest germplasm resources in the Yangtze River Basin. A comprehensive investigation of forest germplasm resources and diversity analyses of important tree species and a preservation system that is composed of in situ, ex situ and vitro preservation is urgently needed.
