摘要: 三江平原沼泽化草甸优势种群-小叶章(Deyeuxia angustifolia)种群地上生物ABI,AAGR,ARGR季节动态均呈单峰型。均至7月末到达到极大值。分别为358.05g/m2,230.96g/m2,14.6830g/d,0.0638g/g·d。BI,AGR,RGR在7月末之前为正,之后为负。极大值均出现在6月末-7月中旬,分别为107. 97g/m2、7.712g/d、0.0274g/g·d。且BI与AGR、RGR, ABI与AAGR、ARGR存在着极显著的线性关系。

Abstract: Deyexia angustisfolia is a dominant species in marsh meadow on Sanjiang plain.its seasonal dynamics of aboveground biomass, ABI, AAGR, ARGR are all as single peak type, reach their maximum values at the end of July, and are 385.05 g/m2, 230.96g/m2, 14.6830g/d and 0.0638g/g·d.respectively, BI, AGR and RGR are positive before the end of July, and negetive after that.Their maximum values are all appeared between the end of June to the middle of July are 107.97g/m2, 7.7121g/d and 0.0274g/g·d respectively.Meanwhile BI with AGR and RGR, ABI with AAGR and ARGR have very significant linear relationships.
