基于多源信息融合理论的盐湖综合监测与洪水预警系统研究——以柴达木盆地那陵格勒尾闾盐湖为例

As one of the most significant strategic resources in China, Salt Lake Resources play important roles in the economic and social development. With the increasing development efforts in recent years, coupled with the impact of climate change, salt lake resources system is experiencing dramatic change, on the one hand, the amount of resource is dynamically changing alone with the improvement of the technology as well as the increasing cognition to salt lake system. On the other hand, the environmental impact of brine industry is becoming increasingly apparent. To better understand the evolving patterns and mechanism of change of modern salt lake, it is critical to obtain accurate and dynamic data from monitoring. Aiming to establish a monitoring and pre-warning system in line with the fundamental characteristics of salt lake resources system, firstly this study frames the concept of integrated dynamic monitoring system of salt lake under the guide of the sustainable theory and Multi-Source Information Fusion Method， and then multiple monitoring indicators are carefully selected from interconnected resource, environment and production system based on their significance to sustainable development. Focused on the optimized layout of monitoring stations, methods of integrating the multi-source data, the study also elaborates the principles, the structure of system, and operational technique of dynamic monitoring, warning models and warning levels. The results of the study fills the gap of the lack of monitoring system of salt lake in China, which contribute to the sustainable development of brine industry in Qinghai Provence as well as western China.

随着人类开采力度的加大和全球变化的影响，盐湖资源系统正在发生急剧变化。准确把握盐湖系统变化规律是制定盐湖资源管理策略和科学合理开发资源的基础。本研究基于可持续发展和多源信息融合理论，从相互关联的盐湖环境、资源和产业多个子系统中选取关键监测指标，从构建理论及原则、综合监测指标选取、多源信息获取及融合、预警模型构建、预警阈值确定、预警层次与方式等方面对构建盐湖资源综合监测与洪水预警系统深入探讨。尝试在案例盐湖区将遥感、超声等多项技术与常规气象水文监测结合，实现北斗卫星无线通信技术及GIS空间分析建模的一体化融合，建立由传感器部分、信息预处理部分、信息融合中心部分和决策控制部分等构成的数据融合系统模式，并构建适合盐湖区特点的洪水预警系统模型。该研究不仅能掌握盐湖对外部环境要素变化和人类干预的响应机制和规律，提高资源利用率,其成功经验的推广对保障盐湖区产业可持续发展与科学管理有重要意义。
