【摘要】：该文提出了一种采用拉力传感设备监测富营养化水体释放气体速率的测定方法,通过拉力传感设备全天候实时标定富营养水体释放气体质量数据,并采用服务器通过无线传感网络采集气体质量数据并标定每条气体质量数据的时间坐标。试验结果表明,该测定方法能够检测出高温光照充足环境下水体近光层气体释放速率范围为57~539 g/(m2·h),低温无光照环境下气体释放范围为49~280 g/(m2·h),从而测定了富营养水体近光层释放气体量随时间的变化特性和气体释放速率与环境光照及温度的相关性。同时,分时段气体释放速率为富营养化水体N2O、N2通量的测定提供了准确有效的数据基础。
[Abstract]:This paper presents a method for monitoring the gas release rate of eutrophication water using pull force sensing equipment, and calibrates the gas quality data of eutrophication water in real time by using pull force sensing equipment. The server is used to collect gas quality data through wireless sensor network and calibrate the time coordinate of each gas quality data. The results show that This method can detect that the gas release rate of the near-light layer of water body under the condition of high temperature and sufficient illumination is 57 ~ 539 g / (m ~ 2 h), and the gas release range is 49 ~ 280g / (m ~ 2 h),) under low temperature and no light environment, and the amount of gas released from the near-light layer of eutrophic water is determined. The dependence of time variation and gas release rate on ambient light and temperature. At the same time, the gas release rate provides an accurate and effective data basis for the measurement of N _ 2O _ 2 fluxes in eutrophication water.
