Species and Faunal Distribution of the Early Spring Ephemeroid Plants of Temperate Forests in Northeastern China
摘要
Abstract
Combining the growth cycles characteristics of early spring ephemeroid plants, this paper made statistics and analysis on the species and faunal distribution of the temperate forests in Northeastern China on the basis of the references and statistics of the flora and literature data. The results showed there were 60 species early spring ephemeroid plants in Northeast China,8 varieties and 15 variants,belonging to 8 families and 22 genera respectively. The families were mainly made up of Ranunculaceae and Papaveraceae, there were 49 species, accounting for 59. 0 percentage of all early spring ephemeroid plants. The dominant genera were Corydalis and Anemone,accounting for one third of all early spring ephemeroid plants. The fauna of genera were divided into 4 types and 1 variant. And the main component was the distribution type of north temperate zone, including 10 genera,49 species,the old world distribution type (6 genera 11 species) secondly.关键词
