摘　　要：文章对白石砬子自然保护区生物多样性进行了系统研究。物种多样性,该区有裸子植物4科8属17种,被子植物90科403属975种,国家重点保护植物10种;有脊椎动物29目79科354种,国家重点保护动物40种,中日保护候鸟协定种127种。生态系统多样性,按地型、森林类型、土壤、气象因子划分了不同地域多种自然生态系统。遗传多样性即基因多样性,自然保护区保证了这种遗传变异整个自然和连续的过程。该文还对生物多样性保护利用提出了建议。s: In this paper, systematic studies of biodiversity in Baishilazi reserve were conducted. As to diversity of plants, there were 4 families, 8 genera and 17 species of gymnosperms and 90 families, 403 genera and 975 species of angiosperms; there were 10 state-level emphasized protective species. There were 29 orders, 79 families and 354 species of vertebrates, there were 40 state-level emphasized protective animal species. There were 127 migrant birds protected by China and Japan agreement. As to diversity of ecosystems, many natural ecosystems in terms of different areas were classified according to terrains, forest types, soil and meteorological factors. As to genetic diversity namely gene diversity, the whole natural and successive process of genetic variation were guaranteed in the natural reserve. Suggestions of protection and utilization of biodiversity were put forward.
