小洪河杨庄水文站和五沟营水文站都属于国家基本站,从二十世纪五十年代建站以来已经有20五十多年实测资料。但从五十多年资料来看,经常会发生区间水量为负值的情况。针对这种特殊现象,文章收集整理了1964-2009年共计46年的实测流量资料,从地貌形态、地质构造及水文地质条件三个方面综合分析了引起地表水资源突变的成因。
Both Xiaoyanghe Yangzhuang Hydrologic Station and Wu’gouying Hydrographic Station belong to the national basic stations, and more than 20 years of measured data have been obtained since the establishment of stations in the 1950s. However, from more than 50 years of data, it is often the case that the interval water is negative. In response to this special phenomenon, the article collected and collected 46 years of measured flow data from 1964 to 2009, and analyzed the causes of the abrupt change of surface water resources from three aspects: topography, geological structure and hydrogeological conditions.
