A data management method and system for environmental traffic

Abstract

The present invention discloses a data management method and system for the environmental flow. The method comprises: obtaining historical data of the water system, and calculating the threshold value of the environmental flow according to the historical data of the water system, wherein the threshold value comprises the basic environmental flow and the suitable environmental flow; obtaining the real-time environment flow of the current water system, comparing the real-time environment flow with the threshold value, and obtaining the real-time environmental flow data deviation; according to the deviation, acquiring a watershed model to carry out adjustment and calculation according to the preset rule, and providing an adjustment scheme of the corresponding watershed; and carrying out three-dimensional visual display on the basic environmental flow data, the suitable environmental flow data, and the real-time environment flow data. According to the method and system disclosed by the present invention, by establishing a data relationship between multiple used models and long time series data, and the environmental flow, and the data relationship is analyzed into a three-dimensional scene that can be rendered so as to realize multi-data visualization management, so that three-dimensional visualization flow management decision based on the long time series data is realized, flow management and determination are facilitated, and repeated manpower calculation work is reduced.

Description

technical field [0001] The invention relates to the technical field of environmental flow, in particular to a data management method and system for environmental flow. Background technique [0002] Environmental flow refers to the water flow that the river needs to maintain. Due to factors such as water shortage in the river basin and development of the river basin, if the environmental flow of the river cannot be maintained, the health of many water-dependent ecosystems will be degraded. According to the actual situation of different watersheds, it is often necessary to determine the factors that need to be calculated and considered in the watershed, for example: the flow rate to improve the water quality of the river is usually combined with the research on the comprehensive prevention and control of regional water pollution; the flow rate to maintain the normal spawning and reproduction of fish, according to The requirements of fish for water depth, water temperature, flo...

Problems solved by technology

Due to the various parameters involved in it, how to find the threshold value of the environmental flow in the long-term sequence of the basic situation of the water system, the historical water use situation, the law of pollutant discharge and the joint operation of the reservoir, and reasonably derive it, in the actual use process , with high complexity and weak operability, has become an urgent problem to be solved; in addition, after the derivation, how to intuitively give decision makers appropriate content support based on the current real-time traffic situation has also become one of the urgent problems to be solved; A large amount of data is generated during the calculation process. In order to understand the calculation process, users sometimes need to establish a suitable relationship among large amounts of data for data display.

At present, the existing environmental flow technology is mainly based on manual measurement and recording, and there is no data management and visual display scheme for environmental flow
