扎龙湿地芦苇生长与水因子关系的研究

Research on Relationship of Reed Growth and Water in ZhaLong Wetland

基于扎龙自然保护区核心区、缓冲区和边缘区芦苇长势不同,研究了三区水的物理、化学综合指标,特别是有机物污染综合指标的差异及其对芦苇生长的影响。实验表明,三区的水硬度非常相近且对芦苇的生长影响不大;三区溶解氧差异显著,溶解氧越高,越有利于芦苇生长;生化需氧量和高锰酸盐指数差异显著,生化需氧量和高锰酸盐指数越低,对芦苇生长越有利。

Reed growth is different in core area,buffer area and border area.We research on influence of physical and chemical comprehensive index,especially difference of organic pollution index to reed growth. Experiment shows that water hardness is very close in thesethree areas and has not much influence on reed grouth.Dissolved oxygen is dissolved oxygen is favorable for reed growth.COD and KMnO4 indexes are different obviously in the three areas,and lower value of them are favorable for reed growth.
