| 中文摘要 | we measured ecosystem co2 fluxes for an alpine shrubland on the north-eastern tibetan plateau, qinghai, china. the study is to understand (1) the seasonal variation of co2 flux and (2) how environmental factors affect the seasonality of co2 exchange in the alpine ecosystem. daytime ecosystem respiration was extrapolated from the relationship between temperature and nighttime co2 fluxes under high turbulent conditions.seasonal patterns of gross ecosystem production, ecosystem respiration and net ecosystem co2 exchange followed highly the seasonal change of aboveground biomass in the alpine shrubland. the net ecosystem co2 exchange was mainly controlled by the variation of photosynthetic photon flux density, while the ecosystem respiration was closely correlated to the soil temperature at 5-cm depth. integrated values of gross ecosystem production, ecosystem respiration and net ecosystem co2 exchange for the period from november 1, 2002 to october 31 2003 were estimated to be 1418, 1155 and 222 g co2 m(-2) yr(-1), respectively. |
