Abstract


Baiyangdian wetland is large Qinghe river system in important water storage hub, it would have a negligible role to maintain the ecological balance of the Hebei Plain. Therefore, the the Baiyangdian Basin water resources situation directly affect the sustainable development of the watershed economic, social, and ecological environment. However, in recent years, under the double impact of global change and human activities, watershed hydrology, surface conditions, consistency was destroyed, the hydrological characteristics change significantly. Baiyangdian surface water resources decreasing surface water level continued to decrease, water levels change frequently; lake district domestic water consumption gradually increased at the same time, the surface water resources has been unable to meet the demand growth, groundwater mining; including Baiyangdian surrounding economic zone industrial developed but there is no surface water resources available for use, groundwater has become a major industrial exploitation of water resources. These reasons are changes in water storage capacity of the Baiyangdian had a great impact, and therefore clear Baiyangdian wetland hydraulic connection between surface water and groundwater, and planning the overall water resources is of great significance. This study is divided into the following aspects: (1) the establishment of the groundwater system. Baiyangdian surface water level and the groundwater level of the surrounding areas as basic data, regression analysis and F, t test using EXCEL data analysis capabilities, based on the correlation coefficient between the the Baiyangdian surface water level with different station groundwater level, in order as the basis for the establishment of the groundwater system, and this system is divided into two zones: core impact area and strongly affected zone. (2) inversion of hydraulic conductivity and specific yield. All district units based on genetic algorithm and groundwater systems, the combination of two-dimensional percolation equation matlab software optimization program. Squared difference given the range of permeability coefficient and specific yield based on the water level optimizer calculated and measured values ??and the minimum as the objective function value. Objective function, constraints and groundwater models form the inverse problem of groundwater, the permeability coefficient and specific yield. (3) analysis of groundwater levels and groundwater discharge per unit width variation. Constant head recharge surface water premise, for high, medium and low water level analysis of groundwater levels and groundwater discharge per unit width variation. Groundwater level variation and groundwater discharge per unit width change in groundwater level changes (single wide flow changes) from horizontal to the relationship between the process to recharge cycle, the vertical analysis of different water levels of groundwater The median annual change (single-wide flow changes) to process to recharge cycle. (4) different partitions groundwater storage. High calculated based on the constant level of surface water recharge groundwater model different partitions in the low three different water level of groundwater storage capacity, and storage capacity on the basis of the horizontal and vertical analysis, storage capacity variation of quantitative methods to the study of the relationship between surface water and groundwater.
