Research Based On Multi-Objective Programming on Allocation of Water Resources in Panjin Shuangtai Estuary Wetland

摘要

In order to restore ecological function of wetland, determine the exploitation plan of water resources reasonably and promote the sustainable development of ecological function in wetland, based on the exploitation and utilization situation as well as the planning objectives of Panjin Shuangtai estuary wetland, this essay focuses on discussing water demand of natural ecological system, water quality of agricultural irrigation and aquaculture, and residential water consumption in wetland. Using various areas of wetland as decision variables and aiming to restore the size of all areas back to that in 2000, this essay takes the view of system engineering as guidance, establishes multi-objective programming model for rational allocation of wetland resources, and makes it able to compare with the other three created configurations plans. Results show that only giving priority to the needs of ecological water consumption of wetland to achieve an efficient use of surrounding water resources can we make the recovery of this wetland better and faster, and therefore achieve a desired sustainable development of ecological function. This has an important significance in leading us to a sustainable development of ecological restoration and constructing a framework of coordinated use of water resources of wetland system.
