The present application relates to the technical field of wild animal habitat reconstruction, and particularly relates to a method and device for constructing habitat of otter in alpine valley region. The technical scheme is as follows: a method for constructing habitat of otter in alpine valley region, comprising the following steps: digging an artificial nest in an external environment where otters live by means of a constructing device, the artificial nest comprises a hole mouth, a tunnel, a nest, an expanded part, a tunnel and a hole mouth which are connected to each other in sequence, and the number of the nest and / or the expanded part is at least one; placing a nest model which is the same as the shape of the artificial nest in the artificial nest, and after the placement is completed, constructing an otter foraging environment near the artificial nest. The present application can artificially construct the habitat of otter in alpine valley region, restore and reconstruct the habitat of otter, and provide excellent foraging sites and habitat nests for otters.

A method of extracting water-soluble minerals from an arid location includes identifying or establishing a channel of flowing water at the arid location, and installing a mat containing seeds, and / or seedlings, and a super absorbent polymer (SAP). A perforated, transparent cover sheet is placed on or above the mat. Water is applied to the SAP, such that both edible and dam-constructing vegetation grows and matures from the mat. Beavers are introduced into the arid location, which eat the edible vegetation and use the dam-constructing vegetation to construct a dam that blocks the channel, thereby flooding a region proximate the channel. After the flood water has dissolved the minerals in the flooded region, it is drained and processed to extract the minerals. The drained water can be remotely processed, or directed to an evaporation pond, where the minerals remain while the water is evaporated, recaptured, and reintroduced into the channel.

The application provides a privacy protection task allocation method based on Beaver triples. The method protects the privacy of task participants and task data through secret sharing, and realizes task allocation under privacy protection with the aid of Beaver triples. The method can select appropriate task participants to execute tasks without exposing privacy, that is, the privacy of users is protected, and the efficiency and effectiveness of the task allocation result are ensured. The method realizes double-target optimization of multi-task allocation, and ensures that the task allocation result meets the effectiveness of the two optimization targets under the premise of privacy protection.
