摘 要:野生林木种质资源是重要的战略性资源,是推动林业生产力发展的基础性要素,野生林木种质资源现状及保护利用研究对维护国家物种安全、生态安全、促进经济社会可持续发展具有重要意义。本文通过普查、重点调查、访问和资料收集等方式对彭州市野生林木种质资源开展了野外调查和数据分析,结果表明:(1)彭州市野生木本植物丰富,有491种,其中,乔木175种,灌木248种,藤本60种。(2)从水平分布来看,野生林木种质资源主要分布在北部至中东部区域,南部平坝区的乡镇几乎没有野生林木种质分布。(3)从垂直分布来看,海拔1500 m以下多为次生的亚热带常绿阔叶林,海拔1500~<2200 m为山地暖温带常绿和落叶阔叶混交林,海拔2200~<2500 m为针阔混交林;海拔2500~3600 m为亚高山针叶林,超过3600 m主要为高山灌丛、裸岩以及小块状的高山草甸。文章针对彭州市野生林木种质资源存在的次生灾害、人为破坏和开发利用程度低等问题,提出加强分级分类保护、动态监测、科学研究和野生种质资源的选育应用等保护措施。Wild-forest germplasm is one of the most important strategic resources and fundamental elements to promote the forestry productivity.However,the development and utilization of wild forest germplasm resources has limited 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,interviews and data collection.The results showed that:(1)Pengzhou City was rich in wild woody plants with 491 species,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 evergreen 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 meadows beyond 3600 m.Finally,some protection measures were proposed,such as graded classification protection,dynamic monitoring,scientific research,as well as the selection and application of wild germplasm resources.
