摘要
调查研究三峡库区野生荷叶铁线蕨的生态环境特征,为荷叶铁线蕨的资源保护及人工培育提供参考依据。采用走访调查、实地踏查与实验分析相结合的方法,对荷叶铁线蕨生长的植被、自然地理环境、气候、土壤营养成份等进行研究分析。此次调查发现三峡库区野生荷叶铁线蕨分布区域快速缩小,很多分布点由于滥采滥挖,经历了从成片分布—块状分布—点状分布—消失的变化历程,目前仅在万州3个乡镇发现有4处野生荷叶铁线蕨分布。荷叶铁线蕨生长环境具有海拔低、坡陡、土层薄、东北坡向、郁闭度高和气候温暖湿润等特征,分布区土壤有机质、有效氮、速效钾含量较高,而速效磷含量低。
The study aims at investigating the ecological environment Adiantum reniforme var. sinense of in Three Gorges Reservoir region,and providing a reference basis for the protection of resources and artificial cultivation of A. reniforme var. sinense. By using the method of investigation,field survey and experimental analysis,the vegetation,natural geographical environment,climate,soil nutrients of A. reniforme var. sinense were studied and analyzed. The survey found that A. reniforme var. sinense distribution area reduced fast in Three Gorges region,a lot of distribution has diminished and vanished due to excessive digging,currently only in 3 towns of Wanzhou there exist 4 wild distribution areas. The growth of A. reniforme var. sinense needs an environment with low altitude,steep slope and thin soil,northeast slope,canopy height and warm and humid climate characteristics,and the soil in distribution has the characteristics of high organic matter,available nitrogen,available potassium,and low available phosphorus content.
