Abstract: The disclosure provides an outdoor device for simulating a pond ecosystem comprising a plurality of simulated ponds connected together by pipelines and including an adjusting pool, a plurality of control groups and a plurality of treatment groups with different concentrations; the plurality of control groups and the treatment groups are randomly distributed in the ponds according to a random draw method or a random allocation method, and the adjusting pool is a transfer station for water inlets and outlets of the ponds. According to the device, the plurality of control groups and treatment groups are arranged in a system, achieving a scale of a middle-scale pond ecological simulation system, which can stimulate an actual complex hydrostatic ecological system including a plurality of aquatic macrophytes, algae, zooplankton, benthos and microorganisms, and evaluate the effects of the complex ecological efficiency caused by chemical pollutants entering an actual water body.
