| 英文摘要 | Microirrigation is one of the most advanced irrigation methods used worldwide. Hydraulic analysis and design is a very important work for microirrigation systems. This paper reviewed the previous research works on hydraulic analysis and design of microirrigation systems and pointed out the problems for future's study. From view point of hydraulics, it was found that any laterals, manifolds or subunits, submains and mains can be analyzed and designed with high accuracy to satisfy required average emitter discharge and water application uniformity whenever a system is laid in uniformly sloped fields or non-uniformly sloped fields, in regular fields or irregular fields using nowadays methods. Manifolds, submains and mains are possible to be designed in varying sizes to minimize the costs of submains and mains or whole systems. The problems for future's study are: (1) to develop more perfect methods in order to minimize the total cost( material cost, labor cost and energy cost) of a whole system; (2) to improve nowadays methods by applying modem geographic information sciences such as GIS ( geographic information system), RS ( remote sensing) and GPS ( global position system) to realize computerization of inputting field topographic information; and(3) to develop intelligent computer software with functions that field topographic information can be inputted automatically, layout and parameters of a whole system can be optimized automatically, and system ichnography and installation maps can be created automatically. |
