澜沧江防洪是关系国民生计的大事,历来都受到国家的高度重视。过去,由于人们难以把握澜沧江流域水情信息变化、洪水现状及演变趋势,致使澜沧江防洪具有很大的被动性。根据防洪工作流程,研究了3S技术在防洪各工作环节中发挥的作用。研究表明,3S技术是澜沧江防洪数据采集的有效手段,确保了澜沧江数据的现势性和防洪工作的顺利开展。
The flood control of the Lancang River is a major event concerning the livelihood of the people and has always been highly valued by the country. In the past, due to the difficulty of grasping the changes of hydrological information in the Lancang River Basin, the status quo of floods and the evolution trend, the Lancang River flood control has great passivity. According to the work flow of flood control, the function of 3S technology in flood control work was studied. The research shows that 3S technology is an effective means of data collection for Lancang River flood control, ensuring the current situation of Lancang River data and the smooth implementation of flood control.
