Problems solved by technology

However, in the reservoir, the concentration of chlorophyll gradually decreases from the surface to the bottom of the water body. When the water intake is at the bottom of the dam, the discharge of chlorophyll is not timely, which is very likely to cause the outbreak of blue-green algae in the reservoir.

Embodiment Construction

[0025] The following takes Taizhou Changtan Reservoir as an example to illustrate the ecological regulation method and the method for determining the water intake level. Of course, other types of reservoirs can also be implemented using these methods.

[0026] 1. Conceptual Model of Ecological Scheduling

[0027] Taking the monitoring results of the reservoir on July 4, 2013 as an example, according to the results of the reservoir on that day, the vertical distribution of chlorophyll concentration has a good corresponding relationship with light transmittance, temperature, pH value and dissolved oxygen. Decrease gradually towards the bottom. According to the principle of continuous equation control, under ideal conditions, the flow velocity at the layer of the water intake of the reservoir is relatively large, and the flow velocity of the layer far away from the water intake is relatively small. It can be seen that the different water intake positions of the reservoir will cau...

Abstract

The invention discloses an ecological reservoir regulation method and a determination method for a water taking level in front of a reservoir dam. Water is taken from a water body of thermocline in front of the dam in a reservoir, the obtained water is drained to a water body below the dam, therefore, the discharge efficiency of chlorophyll in front of the dam is improved, and the refresh rate of a surface water body in the reservoir is increased. According to the ecological reservoir reoperation method and the determination method for the water taking level in front of the reservoir dam, due to the fact that the water is taken from the water body of the thermocline in front of the dam in the reservoir, and the obtained water is drained to the water body below the dam, the discharge speed of the chlorophyll in front of the dam is greatly increased, and accidents of algae outbreak and the like are not prone to occur in the reservoir. The ecological reservoir regulation method and the determination method for the water taking level in front of the reservoir dam can be applied to ecological regulation of the reservoir.

Description

technical field [0001] The invention relates to the technical field of reservoir dispatching, in particular to a reservoir ecological dispatching method and a method for determining the water intake level in front of a reservoir dam. Background technique [0002] While reservoirs bring economic and social benefits to human beings, they also have negative impacts on river ecosystems. Aiming at the problem that the traditional reservoir operation does not pay enough attention to the ecological environment, the ecological operation of the reservoir is an effective measure to reduce the adverse effects of the construction of the reservoir, maintain the health of the river, promote the harmony between human and water, and maintain the sustainable development of water resources. [0003] At present, most reservoirs set the water intake at the bottom of the dam, that is, the water at the bottom of the water body in front of the dam is drawn through the dam to the bottom of the dam ...
