【摘要】 湖北是我国鳞毛蕨属植物资源较丰富的省区之一 ,通过对湖北鳞毛蕨属植物资源的调查和分析发现 :湖北鳞毛蕨属植物的分布随着森林植被的变化而变化。在水平分布上随经度的变化比较明显 ,以鄂西山地丘陵植被区和鄂西南山地植被区分布最为集中 ,由此向西到川东种类递增 ,向东明显减少 ;随着纬度的逐渐降低 ,从北到南种类逐渐增加 ,到鄂西南种类最为丰富 ;鳞毛蕨属植物的地理分布具有明显的区域性更多还原

【Abstract】 Hubei is one of the provinces that is abundant in Dryopteris in China. It was found by investigation and analysis that the distribution of the genus changes along with the vegetation of forest. The horizontal distribution of the genus changes obviously along with the longitude, distribute most concentratedlly in the west Hubei mountain and hill vegetation region and the southwest Hubei mountain vegetation region, it increases from this region to the east of Sichuan along the west and it reduces obviously to the eastward; the water and heat are abundant along with the decrease of latitude, the species increase from north to south step by step, and the species are the most abundant in southwest of Hubei; the geographical distribution of the genus has regional significance.更多还原
