Current Status,Protection and Utilization of Wild Forest Germplasm Resources in Pengzhou City
Wild-forest germplasm is one of the most important strategic resources and fundamental elements to pro-mote the forestry productivity.However,the development and utilization of wild forest germplasm resources has limit-ed to the secondary disasters and human destruction in Pengzhou City,Sichuan Province,China.This article aims to research on the current status,protection and utilization of wild forest germplasm resources for national species and ecological security,in order to promote the sustainable economic and social development.Field investigations and data analysis were conducted on the wild forest germplasm resources,including surveys,key investigations,inter-views and data collection.The results showed that:(1)Pengzhou City was rich in wild woody plants with 491 spe-cies,including 175 species of trees,248 species of shrubs,and 60 species of vines.(2)In horizontal distribution,wild forest germplasm resources were distributed mainly in the northern to central eastern regions,while there was no distribution in townships in the southern plain District.(3)In vertical distribution,the secondary subtropical ever-green broad-leaved forests were mostly found below an altitude of 1500 m,the mixed evergreen and deciduous broad-leaved forests in the warm temperate zone of mountainous areas were at an altitude of 1500～＜2200 m,and the mixed coniferous and broad-leaved forests were at an altitude of 2200～＜2500 m;Subalpine coniferous forest was located at an altitude of 2500～3600 m.There were the alpine shrubs,bare rocks and small patches of alpine mead-ows beyond 3600 m.Finally,some protection measures were proposed,such as graded classification protection,dy-namic monitoring,scientific research,as well as the selection and application of wild germplasm resources.
