湿地土壤磷分级方法研究

A Review on Soil Phosphorus Fractionation Scheme on Wetlands

磷是植物生长发育的必需营养元素之一。植物所利用的磷素主要来源于土壤。湿地作为响应全球变化和人类活动较为敏感的生态系统之一,湿地土壤磷分级越来越受到国内外学者的关注。本文综述了国内外湿地土壤无机磷和有机磷的形态划分、分级方法,对应用较广的磷分级方法进行了总结,以期为国内相关研究提供参考和借鉴。

As an essential element of plant nutrition, phosphorus is one of necessary elements for plants growth mainly derived from soil. Wetland is hypersensitive ecosystem responding to global changes and human activities. The phosphorus fractionation schemes for wetland soils have been paid more and more attention. In this paper, the latest international research advances focused on the wetland soil phosphorus fractionation schemes were summarized in order to provide some references and experiments for relative study.
