【摘要】 贵州省岩溶地区属典型的生态环境脆弱区,也是一个植物多样性较丰富的地区,仅需保护的珍稀濒危观赏植物就有131种、本文分析了贵州岩溶区珍稀濒危观赏植物的现状特征,并从观赏植物本身的生理生态习性、水土组合结构、人类干扰活动等方面探讨了该地区珍稀濒危观赏植物的濒危原因。在此基础上,结合目前西部大开发中生态建设的要求,提出了通过建立岩溶珍稀濒危观赏植物自然保护区和全国性的岩溶珍稀濒危观赏植物迁地保存中心等六条措施来保护岩溶地区受危观赏植物。更多还原

【Abstract】 73% of the total area of GuiZhou province is covered by carbonate rocks and karst landforms are widely distributed, in which the eco-environment is very fragile, but the diversity of plants is considerably rich. Field survey and previous studies indicate that there are 191 plant species (under 38 families) of rare and endangered ornamental plants in GuiZhou karst regions. The authors analyzed the present status and main features of rare and endangered ornamental plants in GuiZhou karst regions in this paper, exploring the endangered causes of these ornamental plants due to adverse karst habitat (such as barren land, etc. ), denudation, over-gathered and eco-environment damage (such as serious soil and water erosion, acid rain, etc. ) in consideration of organisms’ habits and characteristics of rare and endangered ornamental plants. Based on these analysis and requirements of eco-environmental construction in west development of China , the corresponding protective countermeasures for rare and endangered ornamental plants in GuiZhou karst areas were suggested.更多还原
