中国水杉引种研究

水杉(Metasequoia glyptostrobodies Hu & Cheng)是国家一级保护植物。水杉的发现是中国近代植物学界最值得自豪的一件大事,为中国植物学走向世界开辟了道路,被公认为是我国乃至世界二十世纪植物界的重大发现,它不仅对于中国有重要价值,也具有世界意义。水杉引种过程可以说是新中国植物引种过程的一个缩影,在发现50年后成功引种至26个省、市、区和特别行政区以及世界50多个国家和地区,成为我国重要的用材林树种、沿海防护林树种、农田防护林树种、城市绿化树种以及世界上著名的风景景观树种。水杉既为新中国林业的发展提供了重要实证,又是科学技术在林业及社会发展中的重要体现,同时水杉的发展也是我国林学界最值得骄傲的一件大事,是我国科技工作者集体智慧的结晶。该文仅对我国水杉引种学进行系统的论述,对水杉的引种阶段进行了划分,简述26个省、市、区和特别行政区的引种现状,分析了水杉在中国引种区的适生状况和原因。有关在国外的引种及迁地保护情况将另文发表。

Introduction of Metasequoia glyptostroboides Hu & Cheng in China

Metasequoia glyptostroboides Hu & Cheng is the national first class protective plant. The discovery of Metasequoia was one of the most important and interesting events and made important contributions to plant field of China in the past century. It was the most proud event in Chinese modern plant fields and it made A way for Chinese botany to be linked the world. Being generally accepted for an important discovery in the plant field all over the world,it was great importance to China,and also to the world. As one important part of Metasequoia research and development,the introduction process could be thought of A miniature of the New Chinese plant introduction. After more than 50 years of the seedling and afforestation,it has been planted in 26 provinces,municipalities,autonomous regions and special administrative region in China and more than 50 nations and regions in the world,it has become the important tree species for timber forest,the along sea shelter belt forest,the farmland shelter forest,city green forest and scenery and landscape forest. The Metasequoia not only provided the important substantial evidence to the development of the new Chinese forest,but also important symbol to science and technology in the development of forestry and socialism. This review gives A systematical summary on the Metasequoia introduction in China,divides the Metasequoia introduction stages,reports briefly on the present situations of Metasequoia introduction and analyzes its suitable conditions in China. The report of that in the world will be recorded in another review.
