摘要
经样线、样地等调查,甘肃敦煌西湖国家级自然保护区有种子植物80种,隶属23科61属,其中藜科(Chenopodiaceae)11属15种、菊科(Compositae)9属13种,占优势;只有1属1种的极小科有11科,分别占保护区总科数、总属数、总种数的47.8%、18.0%、13.7%;有国家级保护植物7种,省级保护植物4种;植物保护主要存在生存环境受水利工程影响较大、受区域干旱多风沙气候影响深刻、周边社区人为干扰较小但依然存在等问题,应增强保护与管理能力,针对湿地萎缩、土地沙化、盐渍化,虫鼠害引起植被退化等现状,对水资源等统筹调配管理,探索科学有效的环境恢复治理和有害生物监控、无害化控制技术,恢复和维护湿地等生态系统及其平衡。
On-spot investigation showed that there are 80 kinds of spermatophyte in Westlake National Nature Reserve,which belongs to 61 genera and 23 families.Fifteen species from 11 genera belong to Chenopodiaceae,13 species from 9 genera falling to Compositae,dominant family in reserve.There are 11 families with one species in one genus,which accounts for 47.8%,18.0%and 13.7%respectively of total families,genera and species.There are 7 species belonging to China endangered plant list and 4 species belonging to provincial endangered plant list.Plant protection is influenced by hydro-project implementation,regional dry and windy climate and the local community interventions.Efforts should be made to address the problems such as wetland shrinkage,desertification,salination,and pest and rodent damaging.Measures like water resources regulation,environment restoration,pest monitoring and control,wetland ecosystem management were suggested.
