摘要
Abstract
[Objective]To provide reference for promoting the health and stability of Mount Qipan Reservoir ecosystem.[Method]Based on the survey data of the ecological environment and fishery resources of Mount Qipan Reservoir in 2021,a material balance Ecopath model of Mount Qipan Reservoir ecological system was constructed by Ecopath with Ecosim software.The food web structure,transfer efficiency,nutrient interaction relationship and overall system characteristics of the ecosystem were analyzed.[Result]The results showed that the effective nutrient levels of 22 functional groups in the food web of Chipanshan Reservoir ranged from 1.000 to 3.419,and the functional group with higher nutri-tional level is carnivorous fish.There are mainly 5 levels of energy flow,in which the average transfer efficiency from primary producers is 3.13%and the average transfer efficiency from debris is 3.39%.The total production of the system is 36 268.078 t/(km2·a),and the total flow is 86 057.620 t/(km2·a),the connection index and systematic omnivorous coefficient are 0.205 and 0.142,respectively.Total primary produc-tion/total respiration and total biomass/total turnover are 2.106 and 0.003,respectively.[Conclusion]The nutritional structure and system de-velopment of the reservoir are analyzed in this paper,it will provide theoretical basis for the sustainable utilization and scientific management of the ecological environment of the reservoir.关键词
