Abstract

We studied temporal changes in biomass and net primary productivity of alpine grasslands at Tungnath in Garhwal Himalaya. Five different communities with similar elevations were taken for investigation. The above-ground biomass samples were harvested as close to the ground as possible. Similarly, below-ground biomass samples were collected from harvesting monoliths (25 x 25 x 30 cm). Aboveground net primary production was determined as the sum of positive changes in biomass and belowground net primary production was calculated as the difference between peak belowground biomass and preceding minimum biomass. The live shoot biomass increased from May till September in all communities except Trachydium roylei and Polygonum, which peaked in August. The dead shoot and litter biomass first decreased and peaked in all communities in October. Belowground biomass first decreased and then increased towards the end of the growing season. The belowground to aboveground biomass ratio ranged between 0.61-3.08. The aboveground net productivity ranged between 454.8-294.3 g m-2, and the belowground net productivity ranged between 346.3-102.4 g m-2.

青藏高寒草甸不同植物群落生物量生产的时间变化
研究了青藏高原通纳特高寒草地生物量和净初级生产力的时空变化。选取5个海拔高度相近的不同社区进行调查。地上生物量样本尽可能靠近地面采集。同样,从收获的巨石(25 x 25 x 30 cm)中收集地下生物量样本。地上净初级生产量为生物量正变化量之和,地下净初级生产量为地下峰值生物量与之前最小生物量之差。5 ~ 9月,除羊草和蓼外,其余各群落的活枝生物量均呈上升趋势,8月达到高峰。各群落枯枝和凋落物生物量在10月先下降并达到峰值。地下生物量在生长季结束时先减少后增加。地上生物量比在0.61 ~ 3.08之间。地上净生产力在454.8 ~ 294.3 g m-2之间,地下净生产力在346.3 ~ 102.4 g m-2之间。
