| 摘 要： | 荒漠草原生态系统非常脆弱,对环境变化和人类活动干扰敏感,在我国草地碳循环研究中具有非常重要的地位。环境因子和人类活动及其协同作用都会对荒漠草原土壤呼吸作用产生影响,但是关于荒漠草原生态系统土壤呼吸作用研究目前仍相对薄弱。因此,加强在非生长季和不同干扰类型下对土壤呼吸影响的研究,并运用遥感监测技术研究荒漠草原土壤呼吸作用,从整体上把握和认识荒漠草原土壤呼吸作用的规律,对于保护脆弱草原生态、保障草牧业的可持续发展具有极其重要的意义。

Research Progress on Soil Respiration in Desert Steppe Ecosystem |
| |
| Abstract: | The desert steppe ecosystem is particularly vulnerable and sensitive to environment change and human disturbance which plays an important role in the research of carbon cycle in grassland of China. Environmental factors and human activities as well as their synergistic effects affect the soil respiration in desert grassland. However, the studies on soil respiration in desert steppe ecosystem are still limited. Accordingly, it is of great significance to strengthen the studies regarding effect of non-growing season and different disturbance types on soil respiration, to assess the soil respiration of desert grassland by using remote sensing technology and to understand the general rules of soil respiration of desert grassland for protecting the fragile grassland ecology as well as guaranteeing sustainable development of grass and animal husbandry. |
