摘要: 探讨了三江平原以小叶章为优势种的典型草甸、沼泽化草甸、沼泽3个植被类型中小叶章种群高度的变化规律。结果表明,在3个类型中,种群高度的季节动态均呈单蜂型,极大值均出现在7月末,分别为112.67cm、101.61cm、83.88cm。HAGR的季节动态在7月末之前>0,之后<0;典型草甸和沼泽化草甸的极大值出现在6月末至7月中旬,沼泽则出现在6月中旬至6月末;极小值典型草甸出现在8月末至9月中旬,而另2个类型则出现在7月末至8月中旬。HRGR的季节动态与HAGR相同;极大值沼泽化草甸出现在6月末至7月中旬,而另2个类型则出现在6月中旬至6月末;极小值典型草甸出现在8月末至9月中旬,另2个类型出现在9月中旬至10月初。

Abstract: The changing laws of heights of Deyeuxia angustifolia population in three vegetation types,ie.typical meadow,marsh meadow and swamp which are dominated by Deyeu xia angustifolia in sanjang plain are discussed in this paper.The results show that their increasements are all single peak type in the 3 vegetation types,their maximum values all appear at the end of July,respectively are 112.67cm,101.61cm,&83.88cm.The seasonal dynamics of HAGR are higher than 0,before the end of July,and then lower than 0,That maximum values of typical meadow and marsh meadow appear at the end of June to the middle of July,and that maximums appear at the middle to the end of June in swamp;the minimum value of typical meadow appears at the end of August to the middle of July,and,that of the other 2 types appear at the end of July to the middle of August.The seasonal dynamics of HRGR are the same as that of HAGR.The maximum value of marsh meadow appears at the end of June to the middle of July,and that of the other 2 types appear at the middle to the end of June.The minimum value of typical meadow appears at the end of August to the middle of September,that of the other 2 types appear at the middle of September to the beginning of October.
