采用循化、小川、兰州、下河沿、青铜峡、石嘴山、三湖河口、头道拐、吴堡、龙门、潼关、三门峡、花园口、泺口和利津共15个黄河干流沿线水文监测断面,计算各水文监测断面水资源多年平均组成。各水文断面监测项目包括水位、流量、气温、水温、pH、电导率、钙、镁、钾、氯离子、硫酸根离子、碳酸根离子、碳酸氢根离子、离子总量、溶解氧、氨氮、亚硝酸盐氮、硝酸盐氮、高锰酸盐指数、生化需氧量、氰化物、砷化物、挥发酚、六价铬、汞、镉、铅、铜、铁、锌和细菌总数等。基于资源理论,采用指标对黄河干流水量和水质进行了统一度量。根据黄河干流实测数据,对水资源化学、物理和生物进行核算,并分析多年水资源变化趋势以模拟黄河干流水资源空间分布状况。最后,势高概念的提出为进一步量化和比较黄河干流的生态发展状况提供基础。
Hydrologic monitoring sections along 15 major Yellow River mainstreams including Xunhua, Xiaochuan, Lanzhou, Xiahe Riverside, Qingtongxia, Shizuishan, Sanhuhekou, Tau Shui Shui, Wu Bao, Longmen, Tongguan, Sanmenxia, Huayuankou, The hydrological monitoring section of water resources for many years the average composition. The hydrological section monitoring items include water level, flow, temperature, water temperature, pH, conductivity, calcium, magnesium, potassium, chloride, sulfate, carbonate, bicarbonate, total ion, dissolved oxygen, Nitrite nitrogen, nitrate nitrogen, permanganate index, biochemical oxygen demand, cyanide, arsenic, volatile phenol, hexavalent chromium, mercury, cadmium, lead, copper, iron, zinc and total bacteria. Based on the resource theory, a unified measurement of water quantity and quality of the Yellow River main stream was carried out by using indicators. According to the measured data of the mainstream of the Yellow River, the chemical, physical and biological resources of the water resources are accounted for, and the trend of water resources for many years is analyzed to simulate the spatial distribution of water resources in the Yellow River. Finally, the concept of potential high provides the basis for further quantifying and comparing the ecological development of the Yellow River main stream.
