The invention discloses an analysis method and a device for branch habitat replacement protection effect evaluation. The method comprises the steps of acquiring historical environment data of a testedbranch habitat; extracting data about hydrological regime, water quality condition, fish and habitat condition from the historical environment data, and constructing element layer indexes according to the data; extracting sub-index data from data about hydrological regime, water quality conditions, fishes and habitat conditions, and constructing indexes of all element layers; calculating the relative weight of each index according to an analytic hierarchy process; and evaluating the branch habitat substitution protection effect by adopting a comprehensive evaluation method according to the weights of the indexes of the index layers. By implementing the method, technical support is provided for branch habitat replacement protection effect evaluation, and certain reference can also be provided for an industry competent department to perfect a hydropower engineering ecological protection technical standard system.
Description
technical field [0001] The invention relates to the technical field of river environment detection, in particular to an analysis method and device for evaluating the effect of alternative protection of tributary habitats. Background technique [0002] With the progress of society and the improvement of people's awareness of ecological protection, ecological and environmental problems have become an important factor restricting the rapid development of hydropower. Water conservancy and hydropower projects have played a huge role in flood control, power generation, water supply and shipping, and have effectively guaranteed the economic development and social stability of the river basin. But at the same time, the construction of large-scale hydropower projects will also have a significant negative impact on the river ecosystem. [0003] So far, focusing on the protection of fish resources in river hydropower development, commonly used fish protection measures, such as artific...
