湿地植物根系泌氧及其在湿地处理中的应用

Prospect on Radial Oxygen Loss of Wetland Plants in the Wetland

湿地植物的根系泌氧能够使植物根际溶解氧及其微生物分布发生变化,并对湿地中污染物的去除具有一定的积极意义.本文综述了水生植物根系泌氧的特点、原理、影响因素,对目前根系泌氧的测定方法进行了介绍并做了相应的对比,阐述了根系泌氧在湿地处理中的应用.

Radial Oxygen Loss of Aquatic plants can make the distribution of dissolved oxygen and the microorganism change in the plant rhizosphere, and has certain positive sense to for the pollutant elimination in the wetland.The characteristics ,principles and influencing factors of secreting oxygen by aquatic plant roots were reviewed in this paper, the current determination methods of oxygen secreted from the root were introduced and compared, finally the application of root secretion of oxygen and prospect of handling the wetland were explained.
