soil respiration rate

The reason of soil respiration rate increasing in the fenced plots might be the increases of biomass in the belowground and soil water content.

（m2.h）-1，围栏样地土壤呼吸作用的升高可能与地下生物量增加和土壤水分改善有关；

Soil respiration rate at forest plot was higher with the proportion of 75% than that in clear-cut plot during the growing season. Soil temperature had a significant exponential relationship with soil respiration.

整个生长季节皆伐迹地土壤呼吸速率约为林地的75%，土壤温度与土壤呼吸作用存在显著的指数关系。

The effects of environment factors on soil respiration rate in coastal protection forest have been studied.

为了揭示土壤呼吸的日间变化规律，寻找影响土壤呼吸速率强弱的生态因子，从而为海防林的造林营林技术提供重要依据，对胶南沿海混交林和灌木林的土壤呼吸速率及各环境因子进行研究。

Soil warming in a range of temperature will increase soil microbial activity and respiration rate.

在一定温度范围内，土壤变暖提高土壤微生物活性及呼吸率。
