Abstract
Water shortage has become an international problem and this is especially true in China. This paper will detail the process of constructing a GIS-based information system to complete large-scale evaluation for water irrigation efficiency in a rice production region in China. A GIS-based system is built to integrate evaluation models and manage irrigation region actively and present the evaluation result in this paper. The research region is divided into several sub-regions and each sub-region is irrigated differently. After comparison of the results of different irritation methods, the suitable way of irrigation for a certain region can be selected. In this study, each rice production farm field located in sub-regions will be regarded as a basic unit and is digitalized to form spatial database. We monitor all growing stage of paddy rice and record water irrigation and rice yield. The goal is to find region-fit irrigation strategy and thus to enhance the profitability of irrigation water.
