辽河三角洲湿地表层沉积物渗透系数的研究

摘要

In this article,four different habitats of permeability coefficient was measured with disc permeameter in Liaohe River delta wetlands.Four habitats are rice fields,reed beds,suaeda salsa and tidal flat.Permeability coef-ficients of the above habitats have been analyzed and compared,and the distribution map of the permeability coeffi-cient in Liaohe River delta wetlands have been made.It is showed that the maximum value of permeability coeffi-cient is 3.2×10 3~3.4×10 3cm/s,and the average value of permeability coefficient is 1.5×10 3cm/s.%该文利用圆盘渗透仪，对辽河三角洲湿地4种不同的生境进行渗透系数的测定，并对4种生境的渗透系数进行老人分析比较，作出辽河三角洲湿地渗透系数的分布状况图。从图上可以看出，辽河三角洲湿地渗透系数值最大值为（3．2～3．4）×103cm/s，平均值为1．5×103cm/s。
