The paper analyzes and summarizes the following laws of distinctive sediment yield produced in storm floods of the region based on predecessors ' study : storm is the main dynamic force of erosive sediment yield and storm, flood and sediment exist an inevitable relation ; the flood occurring time is concentrated with high peaks and huge volume, suddenly rising and suddenly falling and has decisive influence to the formation of a major flood peak in the middle yellow river ; the main reasons of concentrated coarse sediment of the river is severe erosive sediment yield, strong sediment transporting capacity and high sediment concentration ; the important influence of frequent or continued storm floods happened in he - long reach especially in coarse sediment concentrated region to the sediment transport of the yellow river and ; along with the increase of harnessing, regional flood trend is becoming smaller but the variation of sediment quantity is not obvious and the reaction of peak discharge and flood runoff of majority tributaries are not sensitive, showing that a general and normal engineering works can not effectively control regional major floods especially the sediment of an extraordinary flood
摘要在前人研究的基礎上分析總結了該區特有的暴雨洪水產沙規律：暴雨是侵蝕產沙的主要動力，暴雨、洪水、泥沙之間存在著必然的關系；洪水發生時間集中，峰高量大，暴漲暴落，對黃河中游大洪峰的形成具有決定性影響；侵蝕產沙強烈而粗泥沙集中，輸沙能力強，洪水含沙量高，是黃河粗泥沙的集中來源地；河龍區間特別是粗泥沙集中來源區頻繁或連續的暴雨洪水對黃河輸沙有重要影響；隨著治理水平的提高，區域洪水有減小趨勢，但泥沙量變化不明顯，大部分支流的洪峰流量、洪水含水量反應不敏感，說明一般規模和水平的治理工程還不能有效控制區域大洪水特別是特大洪水的泥沙。 -

Some utilization projects of roof runoff water were also discussed including bringing it into normal water system, independent rainwater utilization system, roof virescence system and infiltration and irrigation system
討論了屋面徑流的幾種利用方案，主要包括納入中水系統、獨立的雨水利用系統、屋面綠化利用系統和滲透回灌系統。 -
The geothermal water can be classified into three categories based on the time when replenishment take place and mixing extent with normal groundwater which are : geothermal water mixing with normal groundwater recharged mainly by the modem meteoric water ; geothermal water mixing with normal groundwater water recharged by both ancient and modem meteoric water ; deep - runoff geothermal water recharged mainly by ancient meteoric water
根據降水補給的年代及混合程度可將地下熱水分為主要由現代大氣降水補給的混合型地下熱水；由現代大氣降水和古代降水補給的混合型地下熱水；主要由古代大氣降水補給的深部循環型地下熱水。
