Plant Flora Characteristic in Dongzheling River Region of Xiaoxing'an Ling
摘要
Abstract
[Objective] The aim was to clear the plant flora characteristic in Dongzheling River Region of Xiaoxing'an Ling.[Method] We analyzed the plant floristic constitute,dominant families and genus constitute and genus geographic elements in Dongzheling River Region of Xiaoxing'an Ling.[Result]There were 486 species belonging to 284 genus and 103 families in the region and the gymnosperm played very important role in local forest vegetation although its limited species numbers.The dominant values of the families were relatively notable,the species were more belonging to the few families,and the families including few species and the families including only species were richness;the dominant values of the genus were not notable,and the families including few species and the families included only species had relatively richness.The genus' s geographic elements of bryophyte plants were more complex,and its dominant geographic element was the North Hemisphere Temperate Zone with some the World elements;the genus' s geographic elements of ferns plants were more few,and its dominant geographic element was the Cold Temperate Zone with the World elements and Torrid Zone and Sub-Torrid Zone elements;the genus' s geographic elements of seed plants were more excessive,its dominant geographic element was the North Temperate Zone,occupying 48.9％,and the percent of the each Temperate Zone was more high,accounting to 81.3％,it showed that the genus' s geographic elements of seed plants were relatively independent.The herbage plants consisted of bryophyte plants and ferns plants were the mainly patterns of pants life that occupied 77.2％.[Conclusion] The results provide theoretical basis for the development and utilization of Rosaceae plants in Xiaoxing'an Ling.关键词
