摘要
距瓣尾囊草是我国特有的濒危物种,仅在涪江上游有分布。该文分析了距瓣尾囊草(Urophysa roch-kii)群落土壤水分、pH和氮素状况。结果表明:距瓣尾囊草群落pH值与水分含量呈显著正相关;pH值、水分与全氮呈显著负相关。距瓣尾囊草群落土壤理化性质受周围植被等因素影响较大。该文的研究结果为拯救这一种濒危植物提供了基础数据。
Urophysa rockii is an endangered species endemic to china. In this paper, soil nitrogen level, pH and water content of Urophysa rockii community are analyzed. The results show that the positive correlation is significant between pH and water content. But the negative correlation is also significant between total -N and pH, or water content. The soil properties of Urophysa rockii community may significantly affected by vegetation.
