On the base of the palmer drought severity model of america and the modificated palmer drought severity model ( 1986 ) , we further modificate the palmer drought severity model in the following aspects ; ? 4 stations were chosen to develope the model and adjust the weighting factor ; ? he potential evapotranspiration for an each month was computed by the penman - monteith equation commended by fao ; ( 3 ) the getting of available water capacity of the soil ( awc ) in each station was based on the data of awc that we can find and the characteristic of soil in each station 在美國帕默爾旱度模式和我國1985年修正的帕默爾旱度模式的基礎上,針對其中存在的問題,從建模選用較多站點、可能蒸散計算采用彭曼?蒙特斯公式和土壤田間有效持水量進一步準確劃分等三個方面進一步修正了帕默爾旱度模式。

We can reach a conclusion , firstly , the gross water capacity , gross sediment capacity and zhang jia shan station of jing - river and xian yang station of wei - rever increase but deposit ratio of lower wei - river decrease . secondly , the sediment deposit of lower wei - river increase in pace with the crease in of sediment from the two station and the level rising of chen village 結果表明渭河下游淤積比隨著涇河張家山站和渭河咸陽站的總水量、總沙量和水流量的提高而降低;渭河下游淤積量隨兩站來沙量的增加,陳村水位的抬高而增加。

The scheme embraces four projects , namely ( 1 ) to build up sluices at anqiu bridge and nanzhou bridge ( and the one at anqiu bridge is the first choice ) so that pollutants can be from entering the lake ; 2 ) as a necessary accessory for the above project , to supplement water capacity from changdang lake as a strategic water source into the protection program , and culvert - pipe plan is recommended from two other alternatives through systematic analysis ; 3 ) to carry out comprehensive realignment for some reed regions which are located at the entrances of the lake , and to develop a wetland ecosystem mainly with some reeds ; and 4 ) to set up a green protection belt right round the lake , including planting reeds at lakebeach , building forest belt , developing bases of green foodstuff and disposing sludges in the lake base 該方案由4個工程子系統組成, ( 1 )截污工程:在岸丘橋和南州橋位置各筑一節制閘(而岸丘橋工程又是首選工程) ,以封住湖泊兩頭入流,杜絕污染物進入水源地的截污工程; ( 2 )引水工程:是截污工程的配套工程,利用下游長蕩湖來補充水量,并對3個引水工程設想進行了系統分析,推薦涵管方案,同時將長蕩湖作為該市戰略水源地一并納入保護體系中; ( 3 )濕地生態處理工程:對進入蕩區前的蘆葦區進行綜合整治,發展以蘆葦為主的濕地生態處理工程; ( 4 )環湖綠色自然保護帶工程:包括建設圍湖蘆葦蕩、環湖林帶、綠色食品基地以及污泥處置。

We set up three soil water treatments : the first was saturation treatment , that is , relative water capacity ( rwc ) of soil approached water holding capacity ( whc ) and keep in 90 % - 100 % , dipped in water to make it renew saturation when rwc depress to 90 % . same to the second treatment ( moderate treatment , rwc : 50 % - 100 % ) and the third treatment ( drought treatment , rwc : 20 % - 100 % ) 共設3種水分處理,第一種飽和處理,土壤相對含水量( rwc )接近田間持水量,保持在90 100 ,當rwc降到90時,浸水使之達到飽和;同樣方法使第二種中度處理和第三種干旱處理的rwc分別保持在50 100和20 100 。
