| 摘 要： | 以构建的次级自然单元植物优先保护评价指标体系及层次分析法运算的结果为依据,对白水江自然保护区植被垂直分布带进行了优先保护评价,评价结果表明植物优先保护的顺序依次为常绿落叶阔叶混交林带、落叶阔叶林带、常绿阔叶林带、针阔混交林带、亚高山针叶林带、高山灌丛草甸带,评价指标的综合值依次为78.60,57.32,57.20,38.18,14.08,3.27.常绿落叶阔叶混交林带拥有亚热带和温带的多种植物种类,同时也是国家重点保护、珍稀濒危、特有、单(寡)型类型集中分布的区域,是保护区植物保护的最优先植被带.评价指标的综合值随海拔梯度由常绿阔叶林带的57.20增至常绿落叶阔叶混交林带的78.60后持续减小,体现了物种多样性随海拔升高的单峰分布格局.这种分布格局主要是由不同海拔梯度所产生的水热状况的差异形成的,同时也与低海拔地区强烈的人为干扰和高海拔山地的面积较小等因素有关.

| Abstract: | The natural unit for building a secondary priority in the protection of plant indicators and AHP was based on the results of operations and on the vertical distribution of vegetation in Baishuijiang nature reserve.The work was carried out with a conservation priority assessment,which showed that the priorities for plant conservation is in such an order:the evergreen and deciduous broad-leaved forest zone,deciduous broadleaf forest,evergreen broad-leaved forest,coniferous forest zone in Asia,high mountain co... |
