【摘要】 为剖析黑龙江省降水、径流、土壤含水量响应关系,以季节为时间尺度,计算全省网格降水、径流和土壤含水量相关系数及比值。其中,降水和径流四季的相关系数均值及春夏秋三季径流与降水比值分别为0.39、0.85、0.55、-0.08和0.23、0.20、0.10;降水和土壤含水量四季相关系数均值及春夏秋三季土壤含水量与降水比值分别为0.31、0.66、0.50、-0.02和0.25、0.08、0.24;四季径流和土壤含水量相关系数均值及春夏秋三季土壤含水量与径流比值分别为0.37、0.58、0.47、0.02和1.12、0.40、2.42。黑龙江省降水-径流、降水-土壤含水量、径流-土壤含水量的响应程度因季节而不同,其响应程度由强至弱为:夏季>秋季>春季>冬季,且冬季相关性极弱,为研究黑龙江省区域各水源转化和季节水资源优化配置提供参考。更多还原

【Abstract】 In order to figure out the relationship among precipitation, runoff and soil water content in Heilongjiang Province, the correlation coefficients and the ratio of precipitation, runoff and soil water content in each grid were calculated on the scale of spring, summer, autumn and winter. The mean correlation coefficient between precipitation and runoff in four seasons and the ratio of runoff to precipitation in spring, summer and autumn were 0.39, 0.85, 0.55,-0.08 and 0.23, 0.20, 0.10,respectively. The mean correlation coefficient between precipitation and soil water content in four seasons, the ratio of soil water content to precipitation in spring, summer and autumn were 0.31, 0.66,0.50,-0.02 and 0.25, 0.08, 0.24, respectively. Except the weak response relationship between the three water sources in winter, the runoff recharge received by precipitation is mainly in spring and summer.The soil moisture content recharge received by runoff is mainly in spring and autumn. The soil water content recharge received by the precipitation mainly in spring and autumn, which provided a reference for the study of regional water source transformation and optimal allocation of seasonal water resources in Heilongjiang Province.更多还原
