The kernel of planning on harnessing the Yellow River is to utilize and to treat the resources of water and sediment of the Yellow River unitedly, including combination of promoting what is beneficial and abolishing what is harmful. In view of distinctive law of water and sediment of the Yellow River, the guiding ideology of planning shou- ld be placed on actual situation of the Yellow River valley, combining flood prevention and sediment reduction, leaving some leeway as considering the prospects of flood prevention and sediment reduction and its overall plan. On evaluation of soil and water conservation of the loess plateau, emphasis should be placed mainly on turning poor and backward into prosperous for the local people, as to sediment reduction for the lower fellow River, it should be considered as another problem with different nature. Based on this point, the classification of type of soil loss area in the loess plateau could not be divided only based on how many sediment being transported to the lower reaches. The author has also put forward some opinions on problems of project layout on the main river, improvement of existing systpms of flood prevention, further study on prossibility of increasing the capability of sediment transport, planning of flow passage into sea and rational utilization of water resources of the Yellow River as well. The author suggests that to strengthen the harnessing and developing works of the delta in the estuary zone of the Yellow River should be carried through the combination of departments concerning on harnessing the Yellow River and departments on petroleum. The opinions on making better and rational utilization of the water resources through technological transformation of taking economizing on water as a key has also been put forward in the paper.

治黄规划的核心是统一安排黄河水沙资源的利用和处理,其中包含着除害与兴利的结合。鉴于黄河的水沙具有其独特的规律,在规划的指导思想上,应强调从黄河流域的实际情况出发,把防洪与减淤结合起来,考虑防洪、减淤的前景及其总体布局时应留有余地。对黄土高原水土保持的评价应该主要着眼于为当地人民治穷致富,为下游减沙应作为另外一个不同性质的问题,应将二者区别开来。基于这一点,不能单从向下游输沙多少的观点来划分水土流失类型区。作者还就干流工程的布局问题、完普现有防洪体系问题、进一步研究增大河道输沙能力的可能性问题、入海流路的规划问题以及黄河水资源的合理利用等问题提出了一些意见。作者建议治黄部门与石油部门结合起来,加强黄河河口三角洲的治理与开发,并提出通过以加强节水为中心的技术改造,促使黄河水资源更好的合理利用。

Exceptionally hard rain occurring between spring and summer in 1991 in Jiangsu and Anhui provinces caused serious flood calamities in Huaihe River and Taihu Lake basins. Such climatic condition causing the torrential rain might appear in the Pearl River Valley, leading to rainstorm with wide area, long duration, high intensity and unfavourable composition. Hence, there exists the possibility of occurrence of extraordinary floods similar to those of 1915 and 1949 types. Regions along the middle and...

Exceptionally hard rain occurring between spring and summer in 1991 in Jiangsu and Anhui provinces caused serious flood calamities in Huaihe River and Taihu Lake basins. Such climatic condition causing the torrential rain might appear in the Pearl River Valley, leading to rainstorm with wide area, long duration, high intensity and unfavourable composition. Hence, there exists the possibility of occurrence of extraordinary floods similar to those of 1915 and 1949 types. Regions along the middle and lower reaches of Pearl River are economically well——developed. Except the North River Grand Levee which has been reinforced according to floods of 100——year frequency, the existing levee works in these regions are only capable of coping with floods of 5——20 year frequencies, failing to meet the needs of economic development. If floods of 1915 type recur, only in the West——North River Delta area, direct pecuniary losses will reach 30 billion yuan. Flood disaster is still the most serious threat to the middle and lower Pearl River. To solve the flood control problem in this area, policies of placing emphasis on flood disposal and combining flood disposal with flood storage should be carried out. Hence, the planned scheme of building three flood control systems of dykes in combination with reservoirs along the West and North rivers, the Yujiang River and the middle and lower reaches of the East River is applicable.

1991年春夏之交,江淮地区发生罕见的暴雨,酿成淮河、太湖流域严重洪涝炎害.从形成暴雨的天气条件看,珠江流域出现类似的天气形势,因而形成范围广、历时长、强度大、组合恶劣的暴雨,发生类似1915年和1949年的特大洪水,是完全可能的.珠江中下游地区经济发展迅速,地区现有的防洪工程,除北江大堤已按100年一遇洪水加固以外,其余堤防均只能防御5年一遇至20年一遇洪水,远不能适应经济发展的需要.如1915年洪水重现,仅珠江三角洲地区的直接经济损失将达300亿元左右.洪灾仍然是珠江中下游的心腹之患.解决珠江中下游的防洪问题,必须贯彻"以泄为主、泄蓄兼施"的方针.建设西北江、郁江及东江中下游等3个堤库结合工程体系的规划方案是适宜的.

Combined storage routing for the upper and the lower reservoirs of pumped storage power plant Based on the analysis on the different characteristics of the floods in reservoir and discharges for power generation of the pumped storage power plant and the conventional hydro station,it is suggested to jointly regulating the floods of the upper and lower reservoirs for the pumped storage power plant.According to the relation of power generation and water pumping in the pumped storage power plant,the discharge...

Combined storage routing for the upper and the lower reservoirs of pumped storage power plant Based on the analysis on the different characteristics of the floods in reservoir and discharges for power generation of the pumped storage power plant and the conventional hydro station,it is suggested to jointly regulating the floods of the upper and lower reservoirs for the pumped storage power plant.According to the relation of power generation and water pumping in the pumped storage power plant,the discharge hydrograph of generating unit and the flood hydrograph of the upper and the lower reservoirs have been combined and superposed in different ways and then the flood hydrograph and the initial regulating water level used for combined flood regulation of the upper and the lower reservoirs have been derived.The calculation results have shown that this method is more reasonable than the conventional method.In addition,the discharge hydrograph of generating units is also very important for normal operation of pumped storage power plant during flood season.

通过对抽水蓄能电站与常规水电站的水库洪水及机组流量不同特点的分析,认为抽水蓄能电站上、下库应联合调洪。根据抽水蓄能电站的发电工况和抽水工况之间的关系,将机组流量过程线与上、下库洪水过程线进行不同的组合、叠加,导出上、下库联合调洪洪水过程线和起调水位。计算结果表明:该方法比用传统方法计算的结果大大合理了。另外,汛期机组流量过程线对抽水蓄能电站汛期的正常运行也有重要的参考价值。
