植被甚至可以通过表面灌溉吸收污水，由其在外城或者乡村地带。 - The main reasons for the growth in drip irrigation are the advantages , which it offers over sprinkler and certain conventional forms of surface irrigation
滴灌是当今世界最先进的灌水技术之一，同传统灌水方式比较具有节水、高产、优质的优点。 - Abstract : based on the principle of balance of surface irrigation water volume , a method for determination of field average infiltration parameter according to the irrigation data is introduced
文摘:本文根据水量平衡原理，提出了利用大田畦灌灌水资料推求土壤入渗参数的方法，在此基础上，又提出了利用波涌灌水流推进和消退资料确定间歇入渗减渗率系数的方法。 - The potential for water - saving can be exploited rationally by the measures , such as engineering measure , adjustment of crop planting structure , exploitation of shallow groundwater , improvement of the surface irrigation manner , development of advanced irrigation technology and improvement of water - saving management in the irrigation area
灌区节水潜力有：采取工程措施、调整作物种植结构、开采浅层地下水、改进地面灌溉方式、发展灌水技术、提高灌区节水灌溉管理水平等。 - In addition , this paper selects the water traveling wave model of the surface irrigation , and realizes the modeling of the water movement , according to the water movement characteristics of surface irrigation . furthermore , the optimization model for irrigation effects is used to produce the calculation pattern in which the water movement model is combined with optimization of technical parameters of irrigation . therefore , it is realized that the optimum unit discharge is calc ulated under the condition of definite length and slope of border check and the optimum length of border check is calculated under the condition of definite unit discharge and slope
与此同时，在分析项目区耕作条件下灌溉水流运动特点的基础上，选择地面灌溉水流运动波模型，实现了地面灌溉水流运动的数值模拟，并利用灌溉效果优化模型，构造了地面灌溉水流运动模拟与灌水技术参数优化相结合的计算模式，实现了定畦长、定坡降条件下的优化单宽流量求解和定单宽流量、定坡降条件下优化畦长的求解，为变灌水条件下优化灌水技术参数的确定提供了强有力的工具。
