Ecological monitoring information management and pre-warning system for river-communicating lakes

Abstract

The invention discloses an ecological monitoring information management and pre-warning system for river-communicating lakes. The system comprises a hydrological module, a water quality and water ecology module, a river beach ecology system module, a species diversity module, a multi-element information mining module and a risk assessment pre-warning and analysis module, wherein the risk assessment pre-warning and analysis module comprises a low-water-level pre-warning module, a species diversity pre-warning module and a eutrophication risk assessment and pre-warning module. According to the system, modern information management functions of data and information electronic storage, data dynamic acquisition and transmission, intelligent query, information display and the like can be realized; the effect of analyzing heterogeneity and diversity of data and ecological characteristics of the data is good; and a monitoring result can be subjected to automatic determination and real-time pre-warning.

Description

technical field [0001] The invention relates to an ecological monitoring information management and early warning system for Tongjiang lakes. Background technique [0002] Lakes have multiple ecological service functions such as regulating water supply, flood control irrigation, aquaculture, and biological habitats. Lake ecological environment protection is of great significance to the economic and social development of river basins and regions. The largest group of freshwater lakes in China is distributed in the middle and lower reaches of the Yangtze River. The construction of the Three Gorges Project has had a profound impact on the ecology and environment of the lakes in the middle and lower reaches of the Yangtze River. Poyang Lake and Dongting Lake have attracted special attention. Due to the particularity of the connection between the Tongjiang lake and the Yangtze River, it is driven by the combination of the Yangtze River and the rivers entering the lake, which affe...

AI Technical Summary

Problems solved by technology

The traditional eutrophication assessment method (the TLI index of the environmental protection department) considers CODMn, TN, TP, SD, and Chla indicators, and the risk characterization is insufficient. It is not suitable for high-nitrogen and phosphorus lakes in the middle reaches of the Yangtze River, and does not consider the hydrodynamic parameters that are relatively difficult to obtain on site. For the Yangtze River The decision-making support for risk management of high-nitrogen and phosphorus lakes in the middle reaches is limited

[0006] However, up to now, no ecol...
