Whether the hydrological rhythms are consistent is judged by comparing the entering flow and the descending flow fluctuation process after the ecological scheduling scheme is implemented, and is judged by the hydrological variation index sigma of the IHA hydrological index under the condition of long-series hydrological data.
The calculation formula of the hydrological variation index sigma is as follows:
in the formula, NobservedThe frequency of a certain hydrological change index value within a flow management target range after the implementation of the ecological scheduling scheme of the water conservancy and hydropower engineering; n is a radical ofexpectedThe frequency of a certain hydrological change index value in a natural hydrological situation falling within a flow management target range; f is the ratio of the length of the hydrological series after the implementation of the ecological scheduling scheme to the length of the natural hydrological series; when 0 ≦ σ | < 0.33, it is considered hydrologicThe rhythms are consistent; when the absolute value of sigma is more than or equal to 0.33, the hydrological rhythm is considered inconsistent.
And taking the range of the mean plus or minus standard deviation of the hydrological indicators, or the range of the hydrological indicator values of 25 percentile and 75 percentile as the flow management target range.

In the first step, reference can be made to 'procedure for making ecological scheduling scheme of hydropower engineering'.
The method inherits the principles of sustainability, adaptability, feedback, scientificity and controllability, follows the law of coordinated development of natural environment and economy and society, aims to maintain the nearly natural hydrological rhythm and guarantee the ecological scheduling effect, and forms the method for optimizing the ecological scheduling scheme of the water conservancy and hydropower engineering based on the adaptive management mode by taking continuous monitoring, scientific evaluation and feedback mechanism adjustment as means.
The following illustrates an example of the calculation of the method of the invention:
if known: a certain hydropower station is a water diversion type development power station, and water diversion power generation causes a water reduction river reach between a dam site and a power generation plant, so that the water reduction river reach has great influence on the spawning propagation of fish protected by the river reach. The hydropower station needs to drain ecological flow of 45-280 cubic meters per second.
Firstly, a preliminary ecological scheduling scheme is formulated. In order to guarantee the water use requirement of aquatic ecology in the water reducing river reach under the dam, the functions, tasks, adjusting capacity and incoming water conditions of the hydropower station are comprehensively considered, dam overflowing facilities are reasonably applied, the relation among various requirements is well coordinated, a preliminary ecological scheduling scheme with operability is obtained by combining the hydrological weather forecasting capacity on the basis of not obviously reducing the power generation benefit, and the requirements of the discharge flow are shown in a table 1. The expected effect of ecological dispatching is to maintain the ecological water demand of the ecological system stability of aquatic organisms and the function of river water environment.

And step two, the hydropower station develops an ecological scheduling test for two years.
And thirdly, carrying out long-term ecological monitoring. The ecological monitoring section and the monitoring content of the hydropower station are shown in a table 2.

And fourthly, carrying out hydrological rhythm analysis. The hydrological rhythm of the warehousing and the let-down daily average flow (see figure 2) of the hydropower station in the spawning and breeding period of the fishes in the first year from 3 months to 8 months is taken as an example for analysis. As can be seen from fig. 2, the hydrologic rhythms of the warehousing daily average flow rate and the let-down daily average flow rate of the hydropower station in the first year are inconsistent to a large extent, and the let-down flow rate requirement of the period (3 months to 6 months) in which the hydrologic rhythms are inconsistent in the ecological scheduling scheme needs to be optimized, and the ecological scheduling test in the second step and the long-term ecological monitoring in the third step are repeated. Then, hydrologic rhythm analysis is carried out, and hydrologic rhythm of the impoundment and let-down daily average flow (shown in figure 3) of hydropower stations in the spawning and breeding period of the fishes in the first year after optimization is taken as an example for analysis. As can be seen from fig. 3, after optimization, the hydrological rhythms of the impounded daily average flow and the let-down daily average flow of the hydropower station in the first year are basically consistent, and the ecological protection effect evaluation in the next step is continuously carried out.
And fifthly, carrying out ecological scheduling effect evaluation, and evaluating the physical structure, aquatic ecology, water quality and wading protection target of the river after the ecological scheduling scheme is optimized.
In the aspect of the physical structure of the river, referring to the river longitudinal communication index in the river and lake health assessment technical guide (SL/T793-2020), no fish facility is built in the hydropower station, the river longitudinal communication index is 1/100 km, and the evaluation result of the index is poor.
In the aspect of aquatic ecology, the diversity of aquatic organisms is evaluated by referring to the Shannon-Wiener index of 'Water and Power engineering aquatic ecology survey and evaluation technical Specification' (NB/T10079-.
In the aspect of water quality, the water quality after the implementation of the ecological scheduling scheme is monitored, and the result shows that the water quality meets the expected III-class water quality standard and achieves the expected effect.
In the aspect of wading protection targets, the hydropower station has no special wading protection target, namely the expected effect is considered to be achieved.
In conclusion, the evaluation of the ecological scheduling effect of the hydropower station shows that: except that the physical structure of the river does not reach the expected effect, the other aspects all reach the expected effect. And after the fish passing facility is recommended to be built to restore the river connectivity, carrying out the next round of ecological scheduling test until the ecological scheduling scheme simultaneously meets the requirements of hydrological rhythm analysis and ecological protection effect evaluation, and finally executing for a long time as the optimal ecological scheduling scheme.
The above-mentioned embodiments are only for illustrating the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to carry out the same, and the present invention shall not be limited to the embodiments, i.e. the equivalent changes or modifications made within the spirit of the present invention shall fall within the scope of the present invention.
