皇甫川流域治理区与原生植被区植物多样性比较研究

Shuitu Baochi Xuebao, 2003
在皇甫川流域,分别选择原生植被区、人工恢复治理区和退化未治理区3个样区,对其物种组成特征、优势种重要值、物种多样性特征等进行了对比分析.结果表明:人工恢复治理区经过20余年的小流域治理,其植被的区系组成、优势种组成和物种丰富度已接近原生植被区,生态优势度则显著高于退化未治理区和原生植被区,但其生活型谱、水分生态类型组成特征与未治理区相似而与原生植被区差异较大,均匀度和信息多样性指数则低于退化未治理区和原生植被区.文中还对流域治理过程中植被重建措施及生物多样性恢复等问题进行了初步探讨.

基于微卫星分析黑龙江省南部小飞鼠种群的遗传多样性

野生动物学报
小飞鼠（Pteromys volans）为树栖夜行滑行类啮齿动物，过去不合理的森林采伐已导致其生存受到一定威胁，亟需对其种群的遗传变化，特别是遗传多样性和近交衰退等种群遗传信息开展进一步评价，增强保护与管理的针对性。利用微卫星分子标记对黑龙江省南部4个小飞鼠种群进行遗传多样性分析。结果显示：8个微卫星位点检测出种群平均等位基因数为12.9（12.0 ~ 14.4）个，有效等位基因数为8.6（8.1 ~ 8.8）个，观测杂合度为0.887（0.832 ~ 0.925），期望杂合度为0.872（0.865 ~
