珠江流域洪水频繁,灾害严重,抵御灾害的能力差,洪水仍是心腹之患。自然灾害不可避免,又没有抗拒自然灾害影响的巨大经济实力,人虽然不能胜天,但采用减灾防灾的措施就成为适应自然的基本思路。流域内防洪任务十分繁重,建立一个高效可靠工程措施与非工程措施相结合的防洪减灾系统是十分必要的。当前,非工程措施能起事半功倍的作用,防汛指挥系统建设是重要的非工程措施。在统一规划、统一标准的前提下建立信息采集、防汛通信、计算机网络、防洪决策为中心的防汛指挥系统建设是当务之急。1.洪水仍然是心腹之患 Floods in the Pearl River Basin are frequent, with serious disasters and poor ability to withstand disasters. Floods are still a problem of confluence. Natural disasters are inevitable, and there is no huge economic power to resist the impact of natural disasters. Although people can not survive, the adoption of disaster mitigation and disaster prevention measures has become the basic idea of ​​adapting to nature. The task of flood control in the basin is very heavy. It is very necessary to establish a flood control and disaster reduction system which combines efficient and reliable engineering measures with non-engineering measures. At present, non-engineering measures can play a multiplier effect and the construction of flood control command system is an important non-engineering measure. Under the premise of unified planning and unified standards, the establishment of flood control command center centered on information collection, flood control communication, computer network and flood control decision-making is a top priority. 1. The flood is still an infatuation
