十八重溪野生植物资源的研究

Study on the Wild Plant Resources in the Shibachong Stream

在调查研究的基础上，笔者统计了十八重溪维管束植物，计有１５９科，４７９属，８２９种。其中蕨类植物３５科，５３属，９３种；裸子植物６科，６属，６种；被子植物１１８科，４２０属，７３０种，在调查的基础上，分析了种子植物各属的区系成分。根据野生经济植物的用途，把区内野生经济植物分为８类：油脂植物、淀粉及糖类植物、芳香油植物、纤维植物、鞣料植物、观赏植物、药用植物和蜜粉源植物。在此基础上。提出野生经济植物合理利用与保护的设想，为进一步研究十八重溪野生经济植物，以及植物资源合理利用与保护提供基础资料和科学依据。

On the basic of investigation and researches.the authors.have found that the vascular plants in the Shibachong streams amount to 829 species.They belong to 279 genera and 159 families.Among them there are 93 species belong to 53 genera and 35 families of the Pteridophyte,and 6 species belong to 6 genera and 6 families of the Gymnosperm and 730 species belong to 420 genera and 118 families of the Spermatophyte.After a detailed study,of the flora composition of every genus of the seed plant,according to the use of the wild economic plants,the authors divide them into 8 types:fat plant,strach and sugar plant.fragrant plant,fibre plant,tanning plant,ornament plant.medicinal plant and honey plant.Based on its data,the paper suggests some consetrvational measures and rational utilization of the wild economic plant resources,in order to provide the readers with basic research data and seientific evidences for further study as well as for the rational utilization and conservation of the plant resources of the region.
