THE EXPLOITATION AND UTILIZATION OF PTERIDOPHYTIC RESOURCES OF BEISHAN IN ZHEJIANG

Beishan lies in the middle of Zhejiang and it is now known that there are 107 species of wild pteridophytes,which belong to 56 genera and 30 families.The composition and distributive regulation of pteridophytes are discussed in the paper.On the basic use of the pteridophytes,the pteridophytes can be classified into 8 types:medicinal pteridophytic resources,ornamental pteridophytes,indicator pteridophytic resources,chemical industrial-raw material pteridophytic resources,pteridophytic resources used to weave and pack,edible pteridophytic resources,forage and green manure pteridophytic resources,and pesticide pteridophytic resources etc.In the end,some suggestion on how to rationally exploit and utilize the pteridophytic resources of Beishan are put forward.
