摘　　要：贵州独有的喀斯特环境特征,形成了丰富多彩的生物类型和栽培品种,表现出丰富的遗传多样性。喀斯特地区独特的地上地下二元结构、地形起伏多变,形成了类型多样的生态系统类型。受冰川影响较小,保留了许多北半球其它地区早已灭绝的古老孑遗和残遗的种类,具有物种高度丰富,特有属种繁多,区系起源古老等物种多样性的特点。喀斯特环境自身的脆弱性,加上人类不合理的开发和利用,使得区内的自然资源和自然环境不断地遭到破坏,物种种类、数量正在急剧地减少。贵州省目前在喀斯特地域建立了37个保护区。Varied and colorful biological types and cultivated species show genetic diversity in the environment formed by the unique physiognomic characters of Guizhou.Extremely varying topography and the unique dualistic system of surface and underground karst area bring rich eco-system types.It retains many antique relict species that have been extinct in many other places of the Northern Hemisphere.The distinguishing features of species diversity are rich species,various endemic species and antique flora genesis.The natural resources and environment are destroyed because of the karst environment,its frangibility and human unreasonable activities.The government of Guizhou has set up 37 reserve areas in karst region,and promulgate series decrees and rules to protect the biodiversity in karst area.
