Abstract: A method for restoring waterbird habitats based on the “ecological leverage” theory is provided. The method includes: Step 1: Determining a target waterbird habitat to be restored based on the ecological environment of a target wetland area; Step 2: Selecting several suitable basic ecological units that are distributed in a scattered, circular, or S-shaped pattern from the target wetland area; Step 3: Optimizing the environment of the selected basic ecological units according to the target waterbird habitat; Step 4: Conducting long-term monitoring of the ecological environment and waterbird population of the optimized ecological units, assessing the restoration of the waterbird habitat, and further optimizing the ecological units based on the assessment results. The method of the present invention achieves an enhancement in waterbird diversity within a region with the minimum ecological space and waterbird habitat restoration efforts.

Abstract: A polyfluoroalkoxy resin and a method of preparing the same. The method includes: S1: charging deionized water, an organic solvent, a surfactant, and a chain transfer agent to a polymerization kettle; S2: after heating to a set temperature ranging from 50° C. to 80° C., charging an appropriate amount of polymerization monomer consisting of tetrafluoroethylene and perfluoroalkyl vinyl ether till reaching a set pressure ranging from 0.7 MPa to 1.5 MPa, followed by charging an initiator to start reaction; S3: adding additional polymerization monomer and perfluoroalkyl vinyl ether polymerization promoter, and maintaining the pressure in the polymerization kettle till end of reaction, whereby a polyfluoroalkoxy emulsion is obtained; S4: condensing, washing, and pelleting the polyfluoroalkoxy emulsion from step S3 to obtain the polyfluoroalkoxy resin.

Abstract: A voice broadcasting control method, a storage medium and an electronic device are disclosed. The control method includes obtaining current state information in response to activating a voice assistant, generating a target control command in response to detecting the current state information being predetermined state information, and executing the target control command to perform a voice control on a voice broadcast of the voice assistant.

Abstract: The invention “simulation device and method for studying the influence of wetland plant litter decomposition on water quality”, belongs to the ecological engineering field. The simulation device comprises a distributing reservoir, a planting pool and a discharge bay, and the three are connected successively through a first-level pipeline; the distributing reservoir is used to supply water to the planting pool; the discharge bay is used to collect wastewater discharged from the planting pool; the planting pool comprises a plurality of planting units; the planting unit is a container-like structure and used to hold the planting substrate and plant wetland plants on the planting substrate. By using the simulation device and/or simulation method of the invention, the whole process of the influence of plant litters especially wetland plants litters on water quality under natural state can be highly simulated and restored.
