Résumé partiel
The river management is closely related to the construction of water ecological civilization.It is of great significance to construct the river information management platform to carry out the river chief system and maintain the long-term and orderly development of rivers.The Guanchuan River is located in Dingxi City of Gansu Province,which is a small and medium-sized river in the arid region of the Loess Plateau.The development and utilization degree of water resources and shoreline resources in Guanchuan River is relatively high,and the channelization of river channels is obvious.There are a series of problems in the course management of Guanchuan River,such as the scattered basic data,the low efficiency of water treatment and the damage of the water ecological environment.Based on the problems existing in channel management of Guanchuan River,this paper carried out the big data,Internet and “3S” technology to build a “river chief system” grid management information system.This system integrated the “river chief system”management system and the grid management method,and realized the fine management of the river by the means of divising the river into multi-level unit grid.The key problems and main conclusions during the establishment process of grid-based management information system,i.e,“river chief system” are summarized as follows :(1)The division standard of river grid management are proposed,and “one water area strip grid and four types of shoreline functional zone grid” are constructed.According to the division method of shoreline control line,the shoreline grid is divided into two levels,which provides the foundation for river grid management.(2)The hydrological data,water management data and shoreline management data of the river course in the study area were collected,and the basic database and management information database of the river course were constructed using GIS platform.The functional modules of the system are designed comprehensively considering the actual demands of the river course,which including six parts:hydrology and water resources,water quality,shoreline grid management,video monitoring,data query and background management.(3)The “LAMP” mode was conducted to develop the system,which including Linux operating system,Apache web server,My SQL database and PHP development language
