辽河三角洲湿地表层沉积物渗透系数的研究

Study on Permeability Coefficient of Surface Sediments in Liaohe River Delta Wetland

摘要:

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。

Abstract:

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 coefficients of the above habitats have been analyzed and compared, and the distribution map of the permeability coefficient in Liaohe River delta wetlands have been made. It is showed that the maximum value of permeability coefficient is 3.2×103~3.4×103cm/s, and the average value of permeability coefficient is 1.5×103cm/s.
