哀牢山楚雄片区野生种古茶树生存现状分析与管护探讨

通过对哀牢山楚雄片区野生种古茶树生存现状分析,探讨该片区野生种古茶树管护经营模式,提出科学可行的对策建议,以改善野生种古茶树生存现状。调查结果表明,云南哀牢山国家级保护区楚雄片区野生种古茶树均为大理茶种,以单株分散生长为主,资源总量较少;天然和天然萌生各占一半,生长前期茶树主干遭受损坏,生长情况一般,生长势主要处于中等状态,幼树更新旺盛,但较大树木较少,竞争后期可能出现衰退的趋势。研究区的野生种古茶树生存现状不够理想,除自然因素干扰以外,管护措施也不到位,仍需加强资源保护力度,注重宣传保护和科研开发协调平衡,破除制约野生种古茶树生存发展障碍,实现地区野生种古茶树资源发展最大化。

华北太岳山草地植物资源调查及分析

草地被誉为地球的“皮肤”,承担着多种多样的重要生态功能。在华北太岳山地区,天然草地分布较广,草地植物种类较多。为全面了解华北太岳山草地植物资源的生长和分布状况,2020年6-10月,选择了3个代表区域,设置了14条样线、32块样方对该地区草地植物资源进行了调查。发现:太岳山共有草地植物37科107属165种,其中主要优势种为莎草科、禾本科、唇形科等植物,亚优势种主要为菊科、蔷薇科等植物,并在沁源县花坡发现中国特有种——突隔梅花草(Parnassia delavayi)的分布。分析表明,菊科植物种群数量虽占优势,但从重要值分析结果可明显看出禾本科和莎草科植物的重要性远高于其他科植物;区域内草种分布不匀,且翠雀(Delphinium grandiflorum)、狼毒(Stellera chamaejasme)、酸模(Rumex acetosa)和毛茛(Ranunculus japonicus)等草地退化指示植物分布范围和数量有增长趋势,持续的发展将导致草地植被结构简单,最终产生不可逆的退化。
