Abstract

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.

Key words: Aboveground biomass, Growth rate, Seasonal dynamics, Deyeuxia angustifolia population, Marsh meadow
