Abstract


Uneven distribution of water resources in northern China , especially in the northwest, perennial drought and water shortage . In the water sector , the irrigation water . Irrigation is a fundamental guarantee of the economic efficiency of agricultural production and the entire irrigation . In reality relative lack of water resources , the timely and adequate irrigation is very important , but our current most of the irrigation area management is still relatively backward . The development of automation and computer information technology to promote the development of water conservancy information . The water industry requires the use of advanced information management tools to improve work efficiency . The main content of this study is to water conservancy information under the framework of irrigation management . Text information in the field of irrigation management research advances , more systematic discussion of a variety of predictive models , including the irrigation area runoff forecast , estimate crop water demand forecast its irrigation water . According to the irrigation district water observations over the years , the establishment of a runoff prediction model , the discussion and analysis of the various forecasting methods and the applicable conditions and crop water requirement based on BP neural network prediction model . On this basis, given the growth period of the main crops irrigation water demand estimation methods . This paper studies the basic structure of the , and IMIS main function of the Irrigation Management Information System (IMIS) , database management, GIS and RS in irrigation management more in-depth discussion . Combination of Gansu Province Shule Irrigation Management Information System research topics in theoretical research and the arid northwest irrigation field research based on analysis of the main problems of the irrigation district water demand forecasting and irrigation management . Understand their business processes on the basis of the analysis of decision-making model in irrigation management , application of the C # language and Irrigation Management Information System for the region .
