摘要:
在黄河三角洲芦苇生物量调查的基础上，研究了滨海湿地水体及土壤的物理化学性质对芦苇生物量的影响。结果表明：（1）由于环境因子的影响，芦苇生物量较低，为56.04~1 668.45 g/m2；地下和地上生物量之比1.25~2.37；（2）在多种影响芦苇生物量的因子中，盐度是最主要的限制因子，生物量随盐度的增加而减少；（3）水深是最主要的促进因子，地上生物量随着水深的增加而增加，而地下与地上生物量之比则随着水深的增加而减少，主要原因在于水深改变了芦苇的植株形态特征（株高、茎粗）和结构（密度）特征；（4）半闭流状态的水体中营养物质含量高，N含量对芦苇的生长有促进作用。
Abstract:
Basing on the field investigation of the biomass of the reed (Phragmites australis) in the Yellow River Delta,we studied the effect of the water body of the coastal wetland and the physical and chemical properties of the soil on the biomass of the reed.The results show that:(1)Affected by the environmental factors,the biomass of the reed is lower ranging from 56.04 to 1 668.45 g/m2;the ratio of the belowground biomass to aboveground biomass is from 1.25 to 2.37;(2)Among various factors affecting the reed biomass,the salinity is the dominant restrictive factor with the increase of which the biomass decrease;(3)The water depth is the most important promotive factor,and with the rise of the water depth,the aboveground biomass increase while the ratio of the belowground to the aboveground biomass decrease.The main reason behind this result is that the water depth changes the morphology characters of the reed plants,such as the plant height and the diameter at breast height,and the structure characters (density);(4)The nutrient substance content in the water body at the state of closed semi-flow is high,and the nitrogen content is productive to the growth of the reed.
