Water area coordination configuration method for optimizing river habitat protection and giving consideration to shipping development

Abstract

The invention discloses a water area coordinated configuration method for optimizing river habitat protection and giving consideration to shipping development, which comprises the following steps of: assigning scores to indexes of each region in a target river reach to obtain a habitat suitability comprehensive score, obtaining suitability distribution of each region in the target river reach, determining an ecological optimal air route center line, and determining an ecological optimal air route center line; assigning scores to the channel boundary distance indexes of the water area outside the channel; and obtaining a river habitat conservation and protection suitability score by combining the habitat suitability comprehensive score and the channel boundary distance assignment, and delimiting a river habitat conservation and protection area. The method for identifying the navigation river habitat conservation protection value degree distribution is provided for the first time, a quantitative basis can be provided for achieving high-value-degree area key protection, and the overlapping conflict problem of a river habitat conservation protection area and a shipping development water area can be effectively relieved.

Description

technical field [0001] The invention discloses a water coordination configuration method, which belongs to the technical field of navigation river protection, and specifically discloses a water coordination configuration method for optimizing river habitat protection and taking into account shipping development. Background technique [0002] For a long time, the ecological protection of the Yangtze River has been highly valued, and the ecological environment has gradually improved, but there is still the problem of mutual obstacles between habitat protection and shipping development. Taking the Yangtze River Trunk Aquatic Nature Reserve as an example, it divides the water area into functional zones with the protection object as the core. As one of the habitat protection measures of the Yangtze River, it plays an important role in the ecological environment of the Yangtze River. However, on the one hand, nature reserves are relatively scattered and widely spaced. Generally, t...

Problems solved by technology

However, on the one hand, nature reserves are relatively scattered in distribution and widely spaced. Generally, there are one or more core areas, and the multiple core areas are connected by buffer zones and experimental areas. distribution law, and cannot meet the length requirements of their migration space, it is difficult to effectively protect the natural and complete life activities of aquatic organisms; There are overlaps, which hinder the development of shipping. For example, the right branch of Hechangzhou Waterway, which is the main navigation channel, has poor inflow conditions and poor navigation conditions in recent years. The diversion ratio of the left branch continues to increase and the navigation conditions are good. The core area of ​​the finless porpoise reserve cannot be used as the main channel, and the effect of the right branch is still not optimistic after renovation, which affects the navigation efficiency of the Hechangzhou waterway and is not conducive to the future development of shipping

On the whole, there are certain limitations in the location selection and functional zoning of the Yangtze River Trunk Nature Reserve, which makes it impossible to fully meet the needs of biological habitats and shipping at the same time
