基于新一代测绘技术的水上水下地形一体化测量及库容测定——以淄博市马踏湖为例

Integrated Topographic Survey and Storage Capacity Measurement Based on New Generation Mapping Technology——A Case Study of Mata Lake in Zibo City

高精度的水上水下地形数据为智慧水利水资源的调度、洪水的演进分析、风险模拟预警以及生态管理提供必要数据支撑。传统的测绘技术获得数据难以满足当前精细化管理需求,本研究以淄博市马踏湖为例,采用新一代无人机和多波束测深系统等测绘技术获取湖区陆表和水下地形数据,并采用密集点云格网法精确计算模拟实验区库容,为湖区水资源生态调度以及智慧化管理提供支撑。

High-precision topographic data on water and underwater provide necessary data support for intelligent water resources scheduling,flood evolution analysis,risk simulation and early warning,and ecological management.Traditional surveying and mapping technology to obtain data is difficult to meet the demand of the fine management.In this study,Mata Lake in Zibo City was taken as an example.A new generation of unmanned aerial vehicle and multi-beam sounding system for surveying and mapping technologies were used to obtain epicontinental and underwater terrain data of the lake.Then the dense point cloud grid simulation method was used to precisely calculatethe capacity of the study area,which can providesupport for the ecological operationand wisdom management of water resources in the lakes.
