摘　　要：该研究在简要介绍沙地生态系统土壤呼吸基础上,对前人关于沙地生态系统土壤呼吸的研究结果进行归纳总结,详细阐述了沙地生态系统中非生物因子(如土壤水分、温度、水分与温度的协同作用、土壤理化性质)和生物因子(如植被类型及根际呼吸、凋落物)对土壤呼吸的影响等问题;并针对这些研究结果提出了当前沙地生态系统土壤呼吸研究存在的问题,以期为生态恢复和建设、维护生态平衡提供参考依据。The study provided a brief introduction to soil respiration in sandy ecosystems and summarized previous research results on soil respiration in such ecosystems.It also discussed in detail the influence of abiotic factors,such as soil moisture,temperature and the synergistic effect of moisture and temperature,and biotic factors,such as vegetation types and root respiration and litter,on soil respiration in sandy ecosystems.Based on these research results,the study identified current problems in soil respiration research in sandy ecosystems,with the aim of providing important references for ecological restoration and construction and maintaining ecological balance.
