Beschreibung:
The hydrologic condition is the basic attribute of the wetland ecosystem, which affects the carbon exchange process between the wetland soil and the vegetation atmosphere, and then affects the change of carbon sink. Artificial water transfer or ecological replenishment is one of the most direct and effective measures used to control wetland saturation levels. The relationship was established, between water flux, water level fluctuation and the influence of artificial water transfer, to discuss the variation of carbon sink and when to implement water transfer and how to control water (water level) to achieve carbon sink in Baiyangdian reed (Phragmites australis) wetland under the influence of artificial water transfer. The research results show the amount of carbon sink is changed only-0.72 gC/m 2 (-0.08%) in spring, and the influence is minimal, which is changed -19.49 kgC/m 2 (-2.10%) in summer, and the adverse effect was great, which is changed 133.85 kgC/m...
