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 % ) 共设3种水分处理，第一种饱和处理，土壤相对含水量( rwc )接近田间持水量，保持在90 100 ，当rwc降到90时，浸水使之达到饱和；同样方法使第二种中度处理和第三种干旱处理的rwc分别保持在50 100和20 100 。
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 该方案由4个工程子系统组成， ( 1 )截污工程：在岸丘桥和南州桥位置各筑一节制闸(而岸丘桥工程又是首选工程) ，以封住湖泊两头入流，杜绝污染物进入水源地的截污工程； ( 2 )引水工程：是截污工程的配套工程，利用下游长荡湖来补充水量，并对3个引水工程设想进行了系统分析，推荐涵管方案，同时将长荡湖作为该市战略水源地一并纳入保护体系中； ( 3 )湿地生态处理工程：对进入荡区前的芦苇区进行综合整治，发展以芦苇为主的湿地生态处理工程； ( 4 )环湖绿色自然保护带工程：包括建设围湖芦苇荡、环湖林带、绿色食品基地以及污泥处置。
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 结果表明渭河下游淤积比随着泾河张家山站和渭河咸阳站的总水量、总沙量和水流量的提高而降低；渭河下游淤积量随两站来沙量的增加，陈村水位的抬高而增加。
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 在美国帕默尔旱度模式和我国1985年修正的帕默尔旱度模式的基础上，针对其中存在的问题，从建模选用较多站点、可能蒸散计算采用彭曼?蒙特斯公式和土壤田间有效持水量进一步准确划分等三个方面进一步修正了帕默尔旱度模式。
