辽河下游湿地植被的保护研究

摘要

辽河下游湿地是我国的重要湿地之一,通过对湿地植物芦苇进行室内、室外实验区的实验研究,总结出芦苇生长所需的最佳环境及水分含盐度. 提出在芦苇生长管理中,应根据芦苇需水规律,实行灌排结合的技术措施,既保证芦苇对水分的需求,又能够合理调节土壤通气状况,增加土壤通透性,促进土壤养分有效分解释放及芦苇根系发育和芦苇的生长,使湿地植物芦苇有一个良好的生长环境.%Liaohe River downstream wetlands is one of the important wetlands in our country, there is the world's largest coastal reed swamp wetland, this paper is based on the reed wetland plants for indoor and outdoor experimental area of experimental research, summed up the reeds grow the best environment and water salinity. Put forward in the reed growth management, should according to the laws of the reed water requirement, the irrigation and drainage combined with technical measures, which guarantee the reed demand for water, and can properly regulate soil aeration condition and increase soil permeability and promote soil nutrient release effective decomposition, promote the growth of reed root development and reed, the reed wetland plants have a good growth environment.
