青海省互助北山林区主要野生木本植物资源调查与分析

该研究采用线路调查、样方调查、访谈等方法，调查青海省互助北山野生木本植物资源现状.结果表明，研究区有208种野生木本植物，分属32科66属.其中，乔木类占比17.79%，灌木类占比74.04%；科属分布集中在少种科(37.50%)、单种科(31.25%)以及单种属(50.00%)、少种属(33.33%)中，说明研究区野生木本植物科属分布具有狭窄性；在属的区系分布中，研究区野生木本植物具北温带特性(50.00%).在用途分类中，观赏类占总种数比最高(35.10%)，其次为药用类(31.25%)和食用类(12.98%).观赏类中灌木占比87.67%，乔木占比12.33%，观赏部位主要是株形；药用类资源中，叶入药(30.77%)、寒性(32.31%)、苦味(44.62%)、清热类药(18.46%)占优势；食用植物以果实类(77.78%)为主.调查结果可为青海省互助北山野生木本植物资源综合开发利用提供参考.

Survey and analysis of main wild forest plants resources in the Beishan Forest Area of Huzhu County in Qinghai Province

Wild woody plants resources in the Beishan Forest Area of Huzhu County in Qinghai Province were investigated with the line， quadrat and interview methods in this word. The results showed that there were 208 species of wild woody plants in the study area， belonging to 32 families and 66 genera. Among them， the arbor accounted for 17.79%， and the shrub accounted for 74.04%. The distribution of families and genera was concentrated in the few species family (37.50%)， single species family (31.25%)， single species family (50.00%) and few species family (33.33%)， respectively， which indicating that the distribution of wild woody plants in the study area was narrow. In the floristic distribution of genus， the wild woody plants in the study area had the characteristic of north temperate zone (50.00%).When classified by use， ornamental type (35.10%) accounted for the highest percentage of total species， followed by medicinal (31.25%) and edible (12.98%). Among the ornamental woody plants， the shrub accounted for 87.67% and the arbor accounted for 12.33%.The ornamental sites were mainly plant forms. Among the medicinal resources， leaves were used as medicine (30.77%)， cold (32.31%)， bitter taste (44.62%) and heat-clearing drugs (18.46%) had the advantage. The main edible plants were fruits (77.78%). These results would provide reference for the comprehensive development and utilization of wild woody plant resources in Huzhu Beishan Forest Area in Qinghai Province.
