Problems solved by technology

[0004] At present, the general research plan for wetland ecology is to collect statistics on soil animals in target wetlands under natural conditions, and quantitatively and qualitatively analyze the impact of wetland changes on soil animals. However, this method has a large workload and high cost. Therefore, designing a It is necessary to simulate the response of soil animals to wetlands with different restoration or degradation degrees with simple structure and convenient operation

Embodiment 1

[0032] See attached figure 1 , a simulation device for soil animals responding to different wetlands provided in this embodiment, the device includes:

[0033] The main box 1, which is open at the top, is used to accommodate the soil, vegetation and soil animals of the target wetland;

[0034] Several auxiliary boxes 2 have the same structure as the main box 1, and each of the auxiliary boxes 2 shares a side wall with the main box 1, and a channel 3 is opened on the side wall, and The channel 3 is located at the upper end of the side wall, and the soil does not pass through the channel 3;

[0035] The water injection assembly is used for injecting water into the main tank 1 and the auxiliary tank 2, which includes a reservoir 3, a water pump 4, a main pipeline 5 and several branch pipes 6, and the water pump 4 is arranged in the reservoir 3, The water pump 4 is connected to the main pipeline 5, and several branch pipes 6 are connected in parallel to the main pipeline 5. Each...

Abstract

The invention belongs to the technical field of wetland ecology, and particularly relates to a simulation device and method for soil animals to respond to different wetlands. The underground water level height and the water temperature of the target wetland are monitored, a main box body with the same water level height and the same water temperature as the target wetland is arranged, soil of thetarget wetland is laid in the box body, vegetation of the wetland is planted, the ecological environment of the wetland is simulated, and the auxiliary box bodies are arranged to be wetlands with different water level heights, so that succession process of wetlands is simulated fully; channels are formed in the side walls of the main box body and the auxiliary box bodies, soil animals respond to wetland environments with different recovery degrees or different degradation degrees, migration and cultivation are conducted for a certain period of time from the channels, vegetation is removed, soil is taken out, and the composition and the number of the soil animals in the main box body and the auxiliary box bodies are counted and analyzed; and the research on the influence of wetland transition on soil animals can be effectively carried out, and a basis is provided for wetland protection and control operation.

Description

technical field [0001] The invention belongs to the technical field of wetland ecology, and in particular relates to a simulation device and method for soil animals to respond to different wetlands. Background technique [0002] Soil animals are nutritional intermediaries between wetland primary producers and secondary consumers, and have characteristic responses or environmental indicators to wetland natural attributes such as wetland hydrological regime, water chemical properties, and vegetation types, as well as wetland quality changes such as wetland pollution and degradation. significance. Soil animals are an important part of the wetland ecosystem structure, and the study of their community structure and changes can provide basic information for in-depth revealing of wetland biodiversity and its functions. [0003] Systematic in-depth study of the composition and distribution characteristics of wetland soil fauna to form an overall framework for the structural charact...
