Embodiment Construction

[0042] The following takes a fish lift project of a hydropower station as an example to explain in detail.

[0043] main fishing season

[0044] The purpose of fish passing facilities is to promote the genetic exchange of upstream and downstream fish populations separated by dams, so the focus should be on ensuring the dam passing needs of the main fish passing objects during the breeding season. The main fishing seasons in the upward direction are determined with reference to the breeding seasons of the main fishing objects, see Table 1. According to the survey, fishes in the Lancang River have two main breeding seasons. The first breeding season is from March to June. Schizothorax is the main species. The breeding water temperature is generally 9-15°C. Schizothorax has the habit of building nests. Mostly lay eggs in the crevices of the gravels prepared by broodstock or adhere to the gravels; the second breeding period is from June to July, which belongs to the Lancang River...

Abstract

The invention relates to a fish dam-crossing analysis method for fish lift engineering. The analysis method comprises the following technical contents: 1) carrying out fish-crossing season analysis; 2) carrying out dam-passing individual specification analysis; 3) carrying out dam passing quantity analysis; 4) analyzing the cluster effect of fishes under the dam; 5) carrying out fish activity daily rhythm analysis; and 6) carrying out fish ecological habit analysis. The method has extremely strong practical experience, theoretical and technical support of fish lift engineering construction isgiven in six aspects, the fish lift engineering constructed on the basis of the theory can completely meet the dam lifting and passing requirements of the dam through practical verification, and due to the fact that early-stage investigation factors are sufficient enough, damage to local ecology is reduced to the minimum, most importantly, sufficient theoretical basis and reliable data parametersare provided for continuous research of later-period fish lift engineering construction influence factor analysis, and the method has extremely high guiding significance.

Description

technical field [0001] The invention belongs to the technical field of a dam crossing analysis method for a fish lifter project. Background technique [0002] The fish lift project is a large-scale project built between the upstream and downstream of the dam, which costs a lot of money. However, different dams have different sizes, and due to the influence of the ecological environment differences between the upstream and downstream fish of the dam, the composition of local fish species is very different. Therefore, when constructing the fish lift project It is necessary to find some indicators and parameters that affect the construction of the project. At present, many dams lack comprehensive indicators and parameters in this aspect when planning and constructing, so more emphasis is placed on the results of the fish lift project, while the theoretical basis for its construction is lacking. The present invention just overcomes this problem. Contents of the invention ...
