阿拉斯加的周报《苔原时报》本周停刊了。

The Tundra Times , a weekly newspaper in Alaska , ceased publication this week .

它们只是在苔原上大嚼特嚼，睡上几小时，接着再吃。

They just chomp on tundra , nap a few hours and feast again .

更暖的北极和更郁郁葱葱的苔原带对于草食动物来说似乎是个好消息。

A warmer Arctic and greener tundra1 might sound like good news for grazing animals .

南极苔原近地面CO2、CH4、N2O浓度和通量的相互关系

Relationships between CO_2 , CH_4 and N_2O Concentrations and Fluxes in Antarctic Tundra

在南极苔原，首次系统地研究了近地面CO2、CH4、N2O浓度及通量的相互关系，结果表明：天气条件对三种温室气体浓度日变化影响较大；

Relationships between CO 2 , CH 4 and N 2O concentrations and fluxes in Antarctic tundra were studied systematically under natural conditions of Antarctica .

风速在地面柳枝和生草丛苔原10cm下几乎减弱为零。

Wind speeds are attenuated almost completely within 10 cm of the ground in willows and tussock tundra .

苔原湿地N2O通量随地下水位的增长而降低，水位是控制N2O通量空间变化的主要因素；CH4通量则受到水位和地温的共同影响。

N2O fluxes from tundra wetlands decreased with increasing water table , so water table affected N2O spatial variation ; CH4 fluxes were controlled with water table and ground temperature together .

本文模拟的结果对于进一步研究南北极生物圈氨的挥发过程和MBP及其对极区苔原生态系统氮磷地球化学循环的影响具有重要意义。

The results of this study are of great significance to further study the process of ammonia volatilization and MBP production , as well nitrogen and phosphorus biogeochemical cycle of Antarctic tundra ecosystems .

高山苔原植物均以低矮形态生长，这是它们最显著的特征。

The most striking characteristic of the plants of the alpine zone is their low growth form .
