System Dynamics Modeling Of Socioeconomic Development Mode Associated With Water Usage In Baiyangdian Lake, Northern China
With continual increase of environmental pressure from human activities, it has become necessary to study the process of socioeconomic water usage influencing the water quality. Based on the system dynamic model developed before to display the whole related flowing processes and the integrated influencing mechanisms of socioeconomic water usage influencing total phosphorus (TP) and total nitrogen (TN), we set 4 types of different socioeconomic development modes (i.e., type of continual status, type of economic development, type of water quality protection, and type of integrated harmonious development) to dynamically simulate and analyze the impact of socioeconomic and ecological water system on TP and TN. Moreover, it indicated that the type of integrated harmonious development was relatively more conducive to balance the water quality condition and economic development, compared to other three modes. Thus, the research could provide a reference to the water resources planning and management, as well as the eutrophication control.
