腾格里沙漠南缘种子植物区系及其资源属性

Flora Resources of Seed Plant in Southern Margin of Tengger Desert

[目的]调查植物区系,分析资源属性,为提高当地居民经济收入,改善农村产业结构提供依据。[方法]以样地调查数据为基础,通过查阅种子植物名录,对种子植物的区系属性、生活型属性和资源属性进行综合分析。[结果]腾格里沙漠南缘有种子植物31种,隶属16科,31属,大科属种为黎科、菊科和禾本科,草本植物最多,占总种数的67.7%,生态植物、饲(食)用植物和药用植物分别占总种数的83.87%,51.61%%和58.06%。[结论]大科属种为黎科、菊科和禾本科,它们在该保护区系中占有重要的地位,表现出它们在该保护区植物区系中的重要性,植物生活型中草本植物最多,生态植物、以饲(食)用植物和药用植物所占比例较大。

[Objective]The objective of the study is to investigate and analyze the seed plant flora resources in order to provide the support for improvement of the economic income of local residents and the structure of rural industry.[Method]Based on collected data,a comprehensive analysis of the characteristics of the area,the life style and the resources of the seed plants was carried out by cousulting the list of seed plant.[Results]In south margin of Tengger desert,there are 31 species of seed plants,belonging to 16 families,31genera and families.The Chenopodiaceae,Compositae,Gramineae and Herbaceous plants accounted for67.7% of the total species.The ecological species,fodder species and medicinal species accounted for83.87%,51.61%% and 58.06% of the total species respectively.[Conclusion]The Chenopodiaceae,Compositae and Gramineae are families with large number of species,and occupied an important position in the flora resources in this region and played a key role in the preservation of flora of the reserve.The herb species are the important life forms,and with the fodder and medicinal species accounted for a larger proportion.
