岷江上游能源植物资源状况初步研究
首发时间:2006-10-20
摘要:能源植物是开发生物质能的基础。对岷江上游能源植物资源的调查研究结果表明,该区能源植物种类涵盖30科44属54种,其中蕨类植物2科2属2种,裸子植物6科12属18种,被子植物22科30属34种;植物类型以乔木为主,占该区所有被统计能源植物的81.48%,灌木和草本分别占11.11%和7.41%;资源主要集中在低海拔地区;某些物种分布范围狭窄或处于濒危状态;一些植物拥有多种开发利用价值。建议在不同海拔地区建立一定数量针对植物资源的自然保护区,并深入开展资源调查研究工作,探索资源开发与经营的合理模式,为21世纪开发生物质能提供材料基础和理论依据。

Investigation on Energy plant Resources in the Upper Reaches of Minjiang River
Abstract:The energy plants in the Upper Reaches of Minjiang River were investigated to provide the resource information for bio-energy development in the future. More than 54 energy plants, belonging to 30 families (2 for ferns, 6 for gymnosperms and 22 for angiosperms), 44 genera (2 for ferns, 12 for gymnosperms and 30 for angiosperms), and 54 species (2 for ferns, 18 for gymnosperms and 34 for angiosperms) were found in this region. The ranked order of energy plants was tree > shrub > herb, which accounted for 81.48%, 11.11% and 7.41% of the total, respectively. The resources of energy plants grew mainly in the low-elevation region, some species existed in narrow zone and endangered, and some species had multiple-value in use except for bio-energy development. It is necessary for plant resource protection to build some nature reserves in different elevation regions. In order to provide the scientific information for bio-energy development in the future, energy plant resources and the technologies of resources exploiture and management were emergent to study deeply.
