The invention belongs to the field of farming and breeding, and particularly relates to a three-dimensional farming and breeding system for performing three-dimensional farming and breeding in wet lands such as lakes, reservoirs and rivers. The three-dimensional farming and breeding system comprises a plant farming floating floor and a mussel breeding tank positioned under the plant farming floating floor, is capable of fully utilizing space, realizing the three-dimensional farming and breeding, namely, a three-dimensional farming and breeding mode that plants are planted and mussels are bred in spaces in an up-down manner, ensuring that different organisms jointly grow in a same environment in a certain breeding space and region, and realizing a farming and breeding mode of keeping the ecological balance and improving farming and breeding benefits, so that the economic benefit is increased, and the characteristics of energy saving, land saving, labor force saving and high benefit are realized.

The invention relates to a water tank type high-density micro-running water mandarin fish culture method, and belongs to the technical field of freshwater economic aquatic product culture. The water tank type high-density micro-running water mandarin fish culture method includes constructing running water tanks, allowing running water at the front and rear ends of the running water tanks to be smooth and keeping micro-running water states; arranging the insides of the running water tanks to be in water body stereoscopic oxygenation modes; arranging ecological wetland conservation regions on the peripheries of the running water tanks and cultivating diversified aquatic plants or aquatic weed floating beds. Fish blocking isolation fences are arranged at water inlet ends and drain ends of therunning water tanks. The water tank type high-density micro-running water mandarin fish culture method has the advantages that current diversified efficient facilities, equipment and technologies arecombined and used with one another, water body stereoscopic oxygenation can be formed by the aid of diversified oxygenation technical measures, micro-running water culture can be implemented, the excellent water quality of water bodies in culture regions always can be kept, the excellent foundation can be laid for high-density efficient culture, and the culture density and the yield per unit of the water tank type high-density micro-running water mandarin fish culture method are at least 5 times or even higher than 5 times the culture density and the yield per unit of existing traditional culture modes; the matched bait fish and running water tank culture regions are connected with one another side by side, accordingly, feeding and domestication management can be facilitated, the management efficiency can be greatly improved, the cost can be reduced, and the benefits can be increased; self-purification and restoration can be carried out on tail water discharged from the culture regions by the wetland ecological conservation regions, and accordingly zero-discharge pollution-free water circulating culture can be implemented.

The invention discloses a reinforced baffling type ecological wetland purification system and a purification method thereof. The reinforced baffling type ecological wetland purification system comprises a buffer settling zone communicated with a water inlet; the buffer settling zone is sequentially connected with a reinforced treatment area, an ecological purification area and a wetland conservation area, and the wetland conservation area is communicated with a water outlet; and diversion submerged breakwaters are arranged in the enhanced treatment area, the ecological purification area and the wetland conservation area, and are arranged in a staggered manner to form an S-shaped water flow channel. According to the enhanced baffling type ecological wetland purification system and the purification method thereof, diversion submerged breakwaters are arranged in an enhanced treatment area, an ecological purification area and a wetland conservation area, and the diversion submerged breakwaters are arranged in a staggered manner to form an S-shaped water flow channel; and the land area of the ecological wetland purification system is reduced.

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.
