Study on the evaluation of GIS technology on surface water resources in the security intelligence perspective

Abstract

Abstract Seeking an efficient and reasonable evaluation method to determine the current evaluation situation of water resources can maximize the protection and utilization of water resources. This paper analyzes the characteristics of previous GIS technology in the evaluation of surface water resources and proposes the establishment of a GIS evaluation optimization model based on security intelligence perspective for the problems of information redundancy and low transmission efficiency of this evaluation method. Firstly, the feasibility and science of constructing a new model under the perspective of security intelligence is discussed, secondly, the development and application of security intelligence theory and the workflow of GIS technology in evaluating surface water resources are reviewed, and finally, the cycle chain of surface water resources evaluation and the optimization model of surface water resources evaluation based on GIS under the perspective of security intelligence are established, and the traditional surface water resources security management system is combined with security intelligence. The security intelligence subsystem and security management subsystem of surface water resources in the intelligence perspective are constructed. The study shows that the surface water resource evaluation model established by GIS technology under the perspective of security intelligence can make up for the deficiencies in information sharing and data standardization of common surface water resource evaluation models, solve the problems of redundancy of massive information and distortion of evaluation results, and provide suggestions for surface water resource evaluation decisions in a certain region or a certain basin.
