为进行模拟气候变化对寒地粳稻的影响，通过在黑龙江省安装开顶式气室（OTC），并进行CO2浓度的测试，分析O T C运行时仪器内气体的稳定性。结果表明：仪器运行时，在气体收集室内，不同高度（50和100 cm）CO2气体浓度变异系数均小于0．04；不同时间（每2 h测一次）和不同天数（连续10 d）OTC内CO2气体浓度变化差异不明显；气体流量与气体收集室内CO2浓度呈线性关系。由此说明，在黑龙江省安装的OTC可以控制气体收集室内CO2浓度，并保持气体浓度稳定性。

In order to simulate the impact of climate change on cold japonica rice ,through install open top cham‐ber (OTC) in Heilongjiang province to test CO2 concentration ,the stability of gas inside the instrument when OTC running was analyzed .The experimental results showed that variable coefficient of gas concentration in different altitude (50 cm ,100 cm)was lower 0 .04 when OTC running .The change of concentration difference was non‐significant in different time(once per two hours) and different day(continuous ten days) .There was a linear relationship between gas flow and CO2 concentration in gas collecting chamber .The experimental results showed that install OTC in Heilongjiang province could control CO2 concentration in gas collecting chamber and keep the stability of gas concentration .
