摘要

[目的

]

结合传统静态气室密闭法的优缺点，探索一种简易静态气室土壤呼吸速率测定方法。[方法

]

针对传统静态气室密闭法测量过程中需补充密闭气室同体积被抽取出的气体样本、仪器设备成本比较高等缺点，设计出本测量方法所需要测量装置。装置主要由静态密闭气室底座、静态密闭气室（桶）以及泵吸式CO

浓度检测仪组成。试验按照给定的实施步骤在野外进行，并以碱液吸收法测量值为标准验证了该方法测量结果的有效性。[结果

]

该方法不仅克服了传统静态气室密闭法测量过程中的缺点，且测量结果准确，成本低廉，操作更为简捷。[结论

]

可以运用于各种野外环境条件下的土壤呼吸速率原位测定。

Abstract

[Objective] A simple closed air chamber method that was expected to overcome the disadvantages of traditional method

was proposed to measure soil respiration rate statically.[Methods] To solve the shortcoming of the traditional static and closed air chamber method

such as refill process of the same volume of gas sample that was taken out and the higher cost of equipment

this measurement method was designed. The apparatus consists of three parts

including a base that was used to set the static closed chamber

a barrel shaped body of static closed chamber and a suction pump detector CO2 concentration of. According to the specific implementation steps

the test was carried out in the field

and compared with the measured value of the alkali absorption method

validity of this method was verified.[Results] The test results showed that this method not only can overcome the shortcomings in measurement process of traditional static closed chamber method

but also is accurate

low-cost

and easy to use.[Conclusion] This method can be applied to various field conditions in soil respiration rate measurement in situ.
