| Research Abstract |
We investigated LAI, soil respiration rate (Rs), environmental factors, biomass and flora of soil microbes in the grassland. The canopy growth was distinguished into four periods, i.e. beginning of growth (late May), exponential growth (from June to July), maximum LAI（early to mid August）, and senescence (September to October). Annual rates were estimated as 3.1 - 3.8 kg CO_2 m^(-2)y^(-1)for Rs, and 2 - 2.5 kg CO_2 m^(-2)y^(-1)for soil heterotrophic respiration. Biomass and flora of soil microbes were heterogeneous spatially (among soil samples), but not seasonally (among sampling periods).
