【摘要】 湖北省辖自然保护区共五座,它们是鄂西神农架自然保护区、鄂西南星斗山、木林子和后河自然保护区、鄂东南九宫山自然保护区。本文根据各自然保护区种子植物区系中优势科、属的分布区类型、属的相似性系数的比较分析和川鄂山区及大别山特有种子植物的地理分布,提供现有五座省辖自然保护区的植物区系地理学依据,并确认其地理布局的合理性。同时,建议尽快在鄂西北和鄂东北(特别是大别山脉)建立一定数量的自然保护区,使湖北省辖自然保护区能准确、完整地反映湖北种子植物区系的全貌和鄂东、鄂西的区域性特征以及与其他相邻区系的关系。更多还原

【Abstract】 Hubei Province has five nature sanctuary under its command. They are Shennungia (N. 31°15′～31°57′,E. 109°56′～110°58′) Nature Sanctuary in W. Hubei, Xingdoushan (N. 30°07′, E. 109°07′),Mubinzi(N. 30°27′, E. 110°23′) and Houhe (N. 30°03′～30°08′, E. 110°30′～110°35′) Nature Sanctuary in S. W. Hubei, Jiugongshan (N. 29°20′～29°25′, E. 114°33′～114°43′) Nature Sanctuary in S. E. Hubei. The paper provides the foundations of the floritic plant geography of five provincial nature sanctuaries on the basis of geographic distributions of the endemic spermatophyte plants in Mr. E. Sichun-W. Hubei and Mr. Dabieshan, the comparative analysis of the genera similar coefficient and the genera types of distributional areas and the dominant families, and affirms their rational layout on the geographic disposition. Meanwhile, author suggests to set up a few nature sanctuaries in N. E. Hubei (specially Mr. Dabieshan) and N. W. Hubei as quickly as possible. The provincial nature sanctuaries, if geographic layout of which were rational, would accurately and integrally reflect a view of the whole Hubei spermatophyte flora and the regional characteristics of E. and W. Hubei and the ralationship with neighbouring flora.更多还原
