It is not natural to attempt to show that the property right arrangement of land is the only condition for determining the agricultural system. The relative scarcity of resources will ultimately determine the institutional arrangement. Such attempts are significant to remind the public about the costs and benefits of water use. In this paper, it is difficult to replace the private cellar with the analysis of the Yellow River irrigation, waterlogging dams, wells and cooperative cellars. The technical choices and project investment and management methods of water conservancy facilities in this area
