Method Of Dividing District For Water-Saving Irrigation Project Programming

Dividing district for water-saving irrigation project programming is an important component of water-saving irrigation planning. It is one of main means to develop reasonably and utilize high-efficiently agricultural water and soil resources. It is one of main bases to confirm the construction scale of the project and take adopt material measure of water-saving irrigation. It is prerequisite and foundation to do well for drawing up water-saving irrigation planning .The rationality of dividing district is one of the important indexes evaluating scientific of water-saving irrigation planning. It is basic guarantee of dividing district reasonably to correct to use scientific method of dividing district .In 1980s,people go all out with agricultural regionalization in the whole country,Once method of dividing district for agriculture planning was regarded as important subject to research., people have studied the ration and calculated method of dividing district too. In the course of actual planning, most staff member of planning rely on own experience and means of qualitative analysis to divide district for water-saving irrigation. Panzhihua city water-saving irrigation planning I participate in is to be no exception. But this kind method of qualitative analysis is simple, lack convincingness. From various kinds of water-saving irrigation project programming recently, it has very strong convincingness to combine qualitative analysis and ration means to divide agricultural water-saving irrigation .It remedies the deficiency of qualitative analysis and ration means .It is a kind of trend of dividing district for water-saving irrigation planning in the future too. But their respective types are varied. Still nobody has explained this question systematically so far .This thesis was just put forward under this kind of background. Important meaning of this thesis is that using scientific method of dividing district can accelerate process of water-saving irrigation planning, and that it offers scientific and reasonable theoretical foundation, and that it sets up the foundation to confirm irrigate measure , pattern of farming , project scale ,etc. This thesis discusses the concept of water-saving irrigation planning , function of water-saving irrigation planning , procedure of working out , index of dividing...
