Problems solved by technology

Although the protection of the Chinese white dolphin has attracted more and more attention in recent years, due to the relatively little understanding of the bioacoustic characteristics of the Chinese white dolphin as an aquatic mammal, in the actual protection process, due to the marine environment Specificity cannot set up isolated areas like terrestrial animals

Embodiment 1

[0038] The acoustic repelling protection method for Chinese white dolphins in the construction sea area, that is, the acoustic wall repelling method, uses a row of bamboo poles at a certain interval on each side of the ship, and a row of bamboo poles with a diameter of about 0.05M and a length of about 2.5M are placed on each side of the ship. The adjacent bamboo poles are fixed with a horizontal bar with a distance of 0.5M, connected to form a row of poles with a length of 5M. The bamboo poles are vertically inserted into the water. A sound wall barrier is formed below, so as to prevent the Chinese white dolphins from straying into the dangerous area.

[0039] In this embodiment, a certain construction point is the center, and several ships (4-8 ships) are arranged depending on different areas, which are evenly distributed in a circle or fan shape, and the driving radius toward the open water is 500 meters. The specific method is as follows: a row of bamboo poles with a diamete...

Embodiment 2

[0041] The study found that when the ship suddenly accelerated or decelerated, the Chinese white dolphin escaped quickly when the noise with varying intensity was generated, indicating that the noise had a direct or indirect impact on its behavior.

[0042] The acoustic repelling protection method of Chinese white dolphins in the construction sea area, that is, the noise repelling method, uses irregularly variable speeds of ships to make irregular noises, prompting Chinese white dolphins to quickly escape from the construction waters.

Embodiment 3

[0044] Before construction, special lookout personnel should be arranged to observe the activities of white dolphins in relevant sea areas. If white dolphins activities are found within 1000 meters of the construction sea area, embodiment 1 and embodiment 2 should be used in combination to prepare Carry out eviction.

[0045] The acoustic repelling protection method of Chinese white dolphins in the construction sea area is about to use the sound wall repelling method and the noise repelling method in combination. The acoustic wall repelling method is to install a row of bamboo poles at a certain interval on both sides of the ship, and the bamboo poles are vertically inserted into the water to a certain depth. When driving away, the bamboo poles are knocked continuously in sequence, and the oscillating waves caused form a sound wall barrier underwater, thereby achieving the purpose of preventing the Chinese white dolphin from straying into the dangerous area; Driving, making ir...

Abstract

The invention discloses an acoustic driving and protecting method for sousa chinensis in the construction sea area. The acoustic driving and protecting method for sousa chinensis in the construction sea area is studied out through the measurement on the sousa chinensis bioacoustics characters, sousa chinensis habitat background noise and construction project noise. The method mainly comprises a sound wall driving method, a noise driving method, an acoustic instrument driving method and a bubble curtain protecting method. The method can be used for driving the sousa chinensis in the oceaneering construction areas and fishery activity water areas, and the sousa chinensis is prevented from being hurt and killed by mistake in the engineering construction and fishery activities.

Description

technical field [0001] The invention belongs to the field of wildlife protection, and in particular relates to an acoustic repelling protection method for Chinese white dolphins in construction sea areas. Background technique [0002] Chinese white dolphin ( Sousachinensis ) is a first-level national key protected wild animal, known as the "Giant Panda at Sea". At present, Chinese white dolphins are mainly distributed in the following five areas in my country: the waters of the Pearl River Estuary in Guangdong, the waters of Leizhou Bay in Guangdong, the waters of Beibu Gulf in Guangxi, the waters of Xiamen in Fujian and the west coast of Taiwan. The waters of the Pearl River Estuary are home to the world's largest population of Chinese white dolphins. Incidents of accidental capture and accidental injury of Chinese white dolphin due to marine engineering construction and fishing activities have occurred from time to time, which has become an important threat to the surviv...
