摘　　要：针对广东省基层技术力量薄弱、防御设施有限的现实情况,提出了构建"一图一册"的基层山洪灾害防御新模式。基于GIS地图制图理论,通过符号抽稀、制图表达、标记分散等地图综合方法,编制了广东省7个地市的县级和镇级山洪灾害防御图和防御手册,推动基层形成"一图一册"的山洪灾害防御体系。同时配套研发了基于WebGIS的防御图册信息管理系统,提供统一的数据访问和安全控制机制,实现防御图册各类数据的可视化展示、动态管理、在线更新以及溯源追踪等功能,有利于保障数据的真实性、准确性和实时性。项目成果能有效打通信息传递的末梢堵塞、解决"最后一公里"的被动决策问题,推动山洪灾害防御业务数据资源的充分共享,进一步增强基层的山洪灾害防御能力。Targeted at the reality of weak technology and limited defense facilities in grassroots department of Guangdong Province,this paper proposes a new model for defensing mountain flood disaster based on“one map and one manual”.Based on GIS mapping theory,through map synthesis methods such as symbol thinning,map representation,and marker dispersion etc.This paper completes making defense maps and defense manuals of mountain flood disaster for 7 cities at county-level and town-level,this would promote the formation of“one map and one manual”mountain flood disaster defense system at the grassroots.At the same time,a WebGIS-based defense atlas information management system is developed,which provides a unified data access and security control mechanism,realizes the functions of visual display,dynamic management,online update and traceability of various data,and helps to ensure the authenticity,accuracy and real-time of data.The results can effectively break through the terminal blockage of information transmission,solve the problem of passive decision-making in the“last mile”,promote the full sharing of data resources for mountain flood disaster defense operations,and strengthen the defense capability of mountain flood disasters at the grassroots level.
