土壤呼吸作用对外界压力的变化非常敏感，生态研究中常要求检测户外土壤在自然条件下的呼吸作用。本文提供了一种应用于土壤呼吸检测设备中动态压力通风装置的设计方案，该装置可使检测设备气室内压强时刻与大气压保持动态平衡，且该装置内部气流速度可被降低到接近地表风速，以此在气室内模拟土壤呼吸作用的自然条件。该装置仅依靠自然风工作，无需电力供应，为户外土壤呼吸检测作业提供了低能源消耗的解决方案。此外，本文还对该设计方案进行了CFD分析，模拟了工作条件下动态压力通风装置的性能，进一步验证了方案设计的可行性。

The measure of carbon dioxide released from soil is of great significance in ecological research. This article provides a design scheme about the dynamic pressure vent in soil respiration detection equipment. The vent can balance the pressure in collection chamber with the atmosphere immediately. At the same time, it can reduce internal air velocity close to the surface wind speed, which provides the simulation of natural conditions of soil respiration in the equipment. Only rely on natural wind, the vent works without power supply, which provides a low energy solution for outdoor detection tasks. Furthermore, to validate the feasibility of the scheme design, this article also concludes the CFD analysis result of the design, which simulated the function of dynamic pressure vent in working condition.
