This utility model provides an insect branch-fixing survey and rearing observation box, relating to the technical field of insect observation devices, and is designed to solve the problem of easy damage to branches in existing insect survey techniques. The insect branch-fixing survey and rearing observation box includes a first half-box and a second half-box. The first half-box has a first upper half-hole and a first lower half-hole, and the second half-box has a second upper half-hole and a second lower half-hole. The first and second half-boxes are joined to form a receiving cavity. When the first and second half-boxes are joined, the first and second upper half-holes together form a first hole for the branch to pass through, and the first and second lower half-holes together form a second hole for the branch to pass through. The first and second holes are respectively sealed to the branch at different locations. Both the first and second half-boxes are made of transparent material, and at least one of the first and second half-boxes has a ventilation window with a detachable mesh screen. This utility model is less likely to damage branches.

The invention discloses a multi-mining-area geophysical exploration optimization method, which belongs to the technical field of geophysical exploration, and comprises the following steps: carrying out geological survey on a target mining area to identify an ore deposit type of the target mining area and analyze a geological background of the target mining area; performing targeted physical property parameter testing, establishing an ore physical property parameter database of different types of ore deposits, and determining a geophysical prospecting mark; selecting and implementing a corresponding exploration technology combination according to the ore deposit type; in the exploration process, multi-scale magnetic survey is implemented hierarchically according to three stages of a metallogenic prospective region, target region optimization and fine exploration, and deep and shallow exploration methods are cooperatively applied; a three-dimensional prospecting model is constructed through multi-parameter joint inversion, and comprehensive interpretation is carried out in combination with the prospecting mark to delineate a prospecting target area; by optimizing the exploration technology combination and the implementation process, the exploration precision and efficiency are improved, the exploration cost is reduced, and reliable technical support is provided for deep prospecting of complex ore deposits.

The application relates to the technical field of hydrological survey, in particular to a floating type hydrological water resource survey device. The device comprises a box, a controller is arranged on one side of the box, a placing box is arranged in the box, a floating plate is arranged on one side of the box, a sleeve pipe is arranged at the bottom of the floating plate, a buoyancy air bag is arranged on the outer surface of the sleeve pipe, the top of the buoyancy air bag is fixedly connected with the bottom of the floating plate, a plurality of through grooves penetrating through the sleeve pipe are formed in the outer circle of the sleeve pipe, and a plurality of filter plates which are matched with the through grooves and are detachably connected with the inner walls of the through grooves are arranged on the outer circle of the sleeve pipe. The device has the advantages of reasonable structure, simple structure, convenient operation, convenient carrying, improved sampling convenience, convenient sampling at different positions of a water area through the floating structure, improved sampling survey accuracy, two-stage adjustment of the survey sampling depth, adjustable sampling depth, high sampling accuracy, and superior shock absorption and buffering performance of the device.
