The invention discloses an artificial fish reef and an artificial fish reef putting method, and belongs to the technical field of water ecological restoration and fishery engineering. The artificial fish reef comprises a reef body, an anchoring structure and a take-up structure. The reef body is of a reinforced concrete frame structure, a bottom plate is closed, other faces are open, protective nets and cross beams are arranged on the side portions, the cross beams are connected through connecting rods, and planting boxes can be installed on the connecting rods. The anchoring structure comprises an anchor hook and an anchor chain, and the take-up structure comprises a take-up box, a take-up roller, a spring and a spring trigger assembly. Through cooperation of the trigger rod and the limiting rod, automatic retracting, releasing and anchoring of the anchor chain are achieved, the structure is stable, installation is convenient and fast, water flow scouring can be effectively reduced, the survival rate of submerged plants is increased, a spawning and inhabiting place is provided for fishes, and the fish gathering effect is remarkably improved.

The utility model provides a kind of farmland type ecological buffer zone structure, it is related to agricultural ecological environment management technical field, including land buffer area one, ecological regulation pond, land buffer area two and concave green land, land buffer area one, ecological regulation pond, land buffer area two and concave green land are sequentially distributed from farmland side to river embankment side, land buffer area one and land buffer area two are planted with arbor shrub and grass flower mat, the ecological regulation pond is sequentially provided with impermeable layer, adsorption layer and plant layer from bottom to top, the concave green land is laid with buffer base, the concave green land is planted with herbaceous plant and shrub. This structure effectively intercepts farmland non-point source pollution, reduces river pollutant, helps to strengthen river self-purification capacity, promotes aquatic animal and plant diversity development, and guarantees ecological benefit to play well.

The application belongs to the field of soil improvement, and relates to a method for applying a modifier for soil acidification in southern forests, by which goethite as a mineral modifier can effectively increase soil pH, adjust soil acidity, improve soil carbon sink capacity, comprehensively improve the plant habitat, and further promote plant growth, so as to simultaneously realize soil habitat improvement and ecological function improvement of the southern forests.
