Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0019] The present invention provides a device for exploring tidal flat dynamic landforms under biological disturbance, which includes a simulated landform tank 1, a three-dimensional laser scanner 20, and a tidal load component. The tidal load component is composed of a simulated tidal tank 6 and a transmission device.

[0020] Such as Figure 1 to Figure 3 As shown, the specific size of the simulated landform water tank 1 can be determined according to the size of the biological type, and a partition 3 is arranged at the end face near the water inlet, wherein the partition 3 is covered with permeable holes 4, and the diameter of the permeable holes 4 should be less than Organisms prevent the passage of organisms and at the same time allow the water level of the simulated landform tank 1 to fluctuate evenly. An impermeable partition 2 is inst...

Abstract

The invention discloses a device for exploring the tidal flat dynamic landform under biological disturbance. The device comprises a simulated landform water tank, three-dimensional laser scanners anda tide load assembly, wherein the simulated landform water tank is equipped with a partition plate equally dividing the chamber into two parts at the transverse position and is equipped with a permeable partition plate at the end face close to a water inlet, the three-dimensional laser scanners are arranged at two sides of the simulated landform water tank and used for observing the change of thetidal flat landform, and the tide load assembly includes a simulated tide water tank and a transmission device. The device can explore the influence of biological disturbance on the sediment and landform of the tidal flat wetland through indoor simulation tests, and the tide load assembly simulates the natural conditions of simple harmonic fluctuation of the tide. Compared with the field tests, the device has the characteristics of high efficiency, low cost, high restoration and the like.

Description

technical field [0001] The invention relates to a device for simulating landforms, in particular to a device for exploring the dynamic landforms of tidal flats under biological disturbance. Background technique [0002] Tidal flat wetland is one of the most widely distributed ecosystems in estuaries and coasts. It is an important area where land and sea interact and is one of the most biologically diverse and productive ecosystems in nature. sand disturbance, landform modification, etc. [0003] As scholars at home and abroad continue to deepen their research on the disturbance of biological activities to sediments, it is found that biological activities can change the physical and mechanical properties of tidal flat sediments, change the role of sediments on wave loads, and play a role in biological feeding, construction and In the process of maintaining the cave, the original structure of the sediment will be destroyed, and the micro-topography and drainage conditions of ...
