Joint Dispatch Of Ecological Service Value Of Reservoir Group Based On Ant Colony Algorithm

The construction of dams to effectively implement reservoir regulation has brought huge service value to human social development,but also produced some negative impacts.For example,it destroyed the health of the river ecosystem to a certain extent,weakened the ecological service function of the river,and reduced the river.Ecological service value,etc.Therefore,it is of great significance and practical value to explore the operation mode of the reservoir in the ecological sense to compensate for its negative impact.Traditional reservoir dispatching pays more attention to economic and safety issues.Although the current ecological dispatch of reservoirs has paid attention to the ecological health of rivers,most of them regard the ecological health of rivers as a constraint rather than a dispatch target,and basically only consider the category of single-reservoir ecological dispatch.Compared with the ecological joint dispatching of reservoirs,the single-reservoir ecological dispatching method is not conducive to the efficient development and utilization of river water resources,is not conducive to effectively maintaining the health of the river ecosystem,and is not conducive to fully exploiting the service value of the river ecosystem.Based on the above research background,this paper discusses the problem of river（reservoir）ecosystem service function and its type classification,the problem of emergy evaluation of river（reservoir）ecosystem service function,and the optimization goal of river（reservoir）ecosystem service energy The problem of joint dispatching of reservoirs,and the solution of bionic algorithm for joint dispatching of reservoir ecosystem services emergy,etc.The core content is arranged in three chapters:Chapter 2 analyzes the energy change,ecological structure,consumer intervention,etc.in the river ecosystem Based on factors,the river ecosystem service functions are divided into 5 primary types and 16 secondary types,focusing on comparing the evaluation methods of river ecosystem service value（value and emergy evaluation methods）,in view of the emergy analysis theory and evaluation The superiority of the method is to construct an emergy evaluation model of the river（reservoir）ecosystem service value,and explain the solution method of the emergy model to provide basic data for the calculation of the river（reservoir）ecological service value;Chapter 3 is based on emergy evaluation The method introduced the evaluation steps of single reservoir ecological service value and reservoir group ecological service value from the perspective of emergy.Based on the comparison with reservoir ecological operation and reservoir ecological service value scheduling,the conventional reservoir group ecological service value single library was established.Dispatching and joint optimization dispatching models,and introducing the corresponding model solving methods,focusing on the ant colony algorithm in optimal dispatching,and providing method references for subsequent chapters;Chapter 4 takes Xinfengjiang Reservoir and Fengshuba Reservoir as examples.The Fengpingku year is a typical year.The ant colony algorithm is used to adjust and calculate the ecological service value of the reservoir group,and its value is evaluated.Through the comparison with the ecological service value of a single reservoir,the ant colony algorithm is tested to solve the reservoir.The practicality of group ecological service value joint dispatch highlights the economic benefits and ecological contribution of joint dispatch.The results of the study show that the total emergy value of the reservoir group’s ecological service value joint regulation is 8.48×10²⁴sej in wet years,6.78×10²⁴sej in normal water years,and 4.58×10²⁴sej in dry years;the changes in the total emergy value of each typical year are as follows:Rainy years>normal water years>dry years.Comparing single-storage scheduling,it can be seen that joint scheduling can produce greater economic value than single-storage scheduling,which is mainly reflected in three aspects:freshwater supply,ecological support and ecological adjustment,accounting for more than 90%of the total value.In terms of ecological environment protection,the joint dispatch of reservoirs plays a more prominent role,mainly in ecological support and ecological regulation.At the same time,it verifies the applicability of the ant colony algorithm in the joint dispatch of reservoirs and can well solve the problems encountered by traditional algorithms."Dimensional disaster"and"local convergence"and other issues.Finally,it embodies the advantages of emergy analysis theory and evaluation methods in the evaluation of river（reservoir）ecological service value,which can be used to compare and study different types and properties of materials or energy.
