Water ecosystem research often involves water sample collection, which contains physical, chemical and biological indexes, however, since it is difficult to ensure that the collection of samples is completed in the same time at different places, the sampling time points are asynchronous, and therefore scientific research data differences are caused, and the regular results are deviated. Conventionally, the measurement of biogenic factors such as carbon, nitrogen, phosphorus, sulfur, silicon and the like is often performed by directly using a water sampler, but in the sampling process, the data result is deviated due to the lowering process of the device and different operations of personnel. Meanwhile, for some suspended particles, the suspended particles are not uniformly distributed in the water body, the measurement of the spatial distribution of the suspended particles is usually completed within a certain period of time, so that the stability and the availability of observed data are achieved, the defects of poor sampling representativeness, trouble sampling and the like exist in the current sampling methods such as a weighing method and a pycnometer method, and the probe is always moved during the measurement without the sampling methods such as a radio method, a conductance method and an isotope method, so that the asynchronization of the measurement result is caused, and the influence on the flow field of the water body is avoided. Importantly, when the hydrologic connectivity research is carried out, the result of the synchronicity of element flux in time and space in the water body is very important for calculating the connectivity. As the hydrological connectivity in the water ecosystem comprises three directions, namely a transverse direction, a vertical direction and a longitudinal direction, the synchronism measurement in all directions is difficult to achieve by one measuring device, which provides an important challenge for scientific research.
