摘要
通过综合运用水均衡法与GRACE重力卫星数据,对黑龙江流域地下水资源进行了系统量化与分析。研究选取黑龙江全流域作为分析对象,采用水均衡法,基于2018年计算得出该年度地下水资源总量为1757.26×10^(8)m^(3)。进一步利用GRACE重力卫星数据反演同期黑龙江流域的地下水资源量,得出结果为1787.21×10^(8)m^(3)。按照科学计算标准两者仅相差1.71%,验证了两种方法在黑龙江流域地下水资源评估中的可靠性。考虑到数据误差与以往研究经验,本研究主要以水均衡法计算结果为准。
By comprehensively applying the water balance method and GRACE gravity satellite data,the groundwater resources in the Heilongjiang River Basin were systematically quantified and analyzed.The study selected the entire Heilongjiang River Basin as the analysis object and adopted the water balance method.Based on the calculation of 2018,the total amount of groundwater resources for that year was 1757.26×10^(8)m^(3).The groundwater resources in the Heilongjiang River Basin during the same period were further retrieved by using the GRACE gravity satellite data,and the result was 1787.21×10^(8)m^(3).According to the scientific calculation standard,the difference between the two is only 1.71%,verifying the reliability of the two methods in the assessment of groundwater resources in the Heilongjiang River Basin.Considering the data errors and previous research experience,the calculation results of the water equilibrium method are mainly taken as the standard in this study.
