Continuous field experiment was carried out on alpine meadow along different elevation gradient in Qilian Mountains during the growing season of 2004 using a soil respiration chamber(Li-6400-09) connected to a portable photosynthesis system(Li-6400).
采用Li-6400便携式光合作用测量系统连接Li-6400-09土壤呼吸室,在2004年生长季节对祁连山高山草甸土壤CO2通量沿海拔梯度进行了野外定位试验,统计分析了水热因子及根系生物量对高山草甸土壤CO2通量特征的可能影响。
),which is covered with alpine meadow,located in the middle reaches of the upper Heihe River,one of the long inland river in Northwest China.
2005年9月—2006年9月,具有较高代表性的3个山坡径流场均没有观测到产流量,结合蒸散发观测和野外调查,发现夏季高山草甸具有明显的地表径流拦蓄和水源涵养作用。
The results showed that in 0-10 cm soil layer,the biomass,length density,surface area density,and volume density of living fine roots were all decreased in the order of evergreen broadleaf forest<dwarf forest<coniferous forest<alpine meadows,with significant differences(P<0.
结果表明:0~10 cm土壤活细根生物量、活细根根长密度、活细根表面积密度、活细根体积密度均是常绿阔叶林<矮林<针叶林<高山草甸,各群落间呈现极显著差异(P<0。

To discuss the pertinence between the vegetation indexes and the aboveground biomass of sub-alpine meadow of Zoige(Ruoergai) County and serve better for the ecological improvement,the statistical analysis was conducted between seven vegetation indexes(NDVI,RVI,DVI,SAVI,MSAVI,PVI and GVI) of Zoige area in July 2008 and the field survey data.
为探讨亚高山草甸地上生物量和植被指数的关系,更好服务于草地生态建设,论文利用2008年7月覆盖若尔盖地区的TM影像,分别建立了7种植被指数(NDVI、RVI、DVI、SAVI、MSAVI、PVI、GVI)与地上生物量的线性和4种非线性(二次多项式、三次多项式、对数、幂函数)回归模型。
