Problems solved by technology

[0002] Most of the existing research focuses on the evaluation indicators of inland river ecological channels. Due to the influence of the dual dynamics of runoff and tidal currents, the water and sediment environment and channel characteristics of tidal estuaries are quite different from those of inland waterways.

Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with examples and tables.

[0035] The tidal estuary ecological waterway evaluation index system described in the present invention provides a quantitative technical evaluation system for the ecological waterway evaluation, and is applicable to the tidal estuary ecological waterway evaluation work. The present invention is described in detail by taking the "eco-channel evaluation of the first-phase engineering project ecological channel regulation of the Yangtze Estuary South Passage" as an example.

[0036] 1. According to the natural conditions, ecological environment, channel attributes and other characteristics of the ecological waterway in the first phase of the Yangtze Estuary South Passage Improvement Project, analyze the basic characteristics and requirements of the construction of the South Passage ecological waterway: C10), tidal flat vegetation (C22) and important species (C27) are...

Abstract

The invention discloses a tidal estuary ecological channel evaluation method, which starts from the whole process of ecological channel design, construction, operation and maintenance, defines a tidal estuary channel construction target and ecological service function, sets a plurality of criterion layers according to the connotation of an ecological channel according to tidal estuary natural conditions, ecological environment conditions, channel construction and construction conditions and the like, and provides evaluation index layers and instructions thereof for the criterion layers, thereby providing quantitative technical evaluation for the ecological channel. The connotation of the ecological channel comprises smooth shipping, eco-friendliness, resource conservation and coordinated development. The criterion layers include twelve criterion layers including tidal estuary river regime conditions and the like. 52 evaluation index layers and instructions thereof are provided for each criterion, a quantitative technical evaluation system is provided for ecological channel evaluation, and corresponding evaluation content or characterization parameters are formulated. The method is suitable for tidal estuary ecological channel evaluation work and guiding ecological channel engineering construction and management.

Description

technical field [0001] The invention belongs to the technical field of waterway regulation engineering evaluation and relates to an evaluation index system for tidal estuary ecological waterways. Background technique [0002] Most of the existing research focuses on the evaluation indicators of inland river ecological channels. Due to the influence of the dual dynamics of runoff and tidal currents, the water and sediment environment and channel characteristics of tidal estuaries are quite different from those of inland waterways. With the gradual development of ecological protection and ecological restoration technologies for waterway regulation projects, it is urgent to establish a scientific, instructive and operable tidal estuary ecological waterway evaluation index system to effectively evaluate and test the construction results of tidal estuary ecological waterways. Provide scientific basis for macro decision-making and shipping management of waterway construction. Co...
