气候变化作用下某湖泊水资源量变化分析

ExperimentalStudy on Creep and Structural Properties of Soft Soil Based on Different Stress Conditions

以河北石家庄某湖泊为对象,通过水均衡法,建立湖泊水资源量化分析模型,并将模型模拟结果与实测值进行比对。结果表明,对比4个水文观测站的实际观测值,实测径流量与模型模拟的径流量吻合程度较高,因此模型的模拟精度较好,误差在可控范围内,具备一定的适用性;通过对土中水量、径流水量与地下水量3种类型的水量进行计算,土中水变化值4年均呈现出负均衡的状态,而地下水的变化量总体呈现出正均衡的变化趋势;通过模拟不同的温度与降雨量场景,结果均表明降雨量为湖泊A区域水资源量变化的主要影响因素。

This paper takes a lake in Shijiazhuang,Hebei province as the object,establishes a quantitative analysis model of lake water resources through the water balance method,and compares the simulation results of the model with the measured values.The results show that the simulated runoff has a high degree of agreement,so the simulation accuracy of the model is good,the error is within the controllable range,and it has a certain applicability.The change value of water in soil shows a negative equilibrium state in 4 years,while the change amount of groundwater shows a positive equilibrium change trend in general;by simulating different temperature and rainfall scenarios,various results show that the rainfall is the same as the water in the lake A area.The main influencing factors of resource change.
