锡林郭勒草原国家级自然保护区种子植物区系研究北大核心CSCD

该研究以查阅文献和野外实地调查相结合的方法,对锡林郭勒草原国家级自然保护区种子植物进行调查、统计、排序,并对该区系种子植物的种类组成、水分生态类型、生活型及种的地理成分进行分析。结果表明:锡林郭勒草原国家级自然保护区有野生种子植物856种,分别隶属于87科,345属;其中,裸子植物3科,5属,11种;被子植物84科,340属,845种。植物水分生态类型以中生植物为主,共559种,占区系总种数的65.30%;旱生植物213种,占区系总种数的24.88%。生活型以草本植物为主,占区系总种数的88.67%。区系中种的地理成分较为复杂,既反映出保护区植物地域性强的特征,也反映出该区域生境类型多样、植物丰富度高的特征。

Analysis on Seed Plants Flora of Xilin Gol Grassland National Nature Reserve

Based on literature review and field investigation, the seed plants flora of Xilin Gol Grassland National Nature Reserve were investigated and analyzed. Meanwhile, the species composition, water ecotypes and geography elements of seed plants in this area were counted by statistic method. The results showed that there are 856 species wild seed plants which belong to 345 genera and 87 families. Of which, there are 11 Gymnosperms species which belong to 5 genera and 3 families; 845 Angiosperm species which belong to 340 genera and 84 families. There are 559 species of mesophytes, accounting for 65.30% of the total species of the flora; and 213 species of xerophytes, accounting for 24.88% of the total species of the flora. The lifestyle is mainly herbaceous plants, accounting for 88.67% of the total species of the flora. The types of floristic geographical elements are complex, which reflects not only the strong regional characteristics of plants in the reserve, but also the characteristics of diverse habitat types and high plant richness in the region.
