AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively study and quantify the multidimensional and heterogeneous impacts of reservoir impoundment on the local climate of the reservoir area. There is a lack of quantitative analysis methods for spatial differentiation characteristics, which affects the stability and integrity of the reservoir area's ecosystem.

Method used

This study employs a combination of Theil-Sen trend analysis and LSTM model to isolate the impact of global climate change, quantify the effects of reservoir water storage on climate elements such as temperature, precipitation, wind speed, and humidity, identify dominant environmental factors for zoning, use an improved Theil-Sen trend analysis method to clarify the nature of the impact, and quantify the specific degree of impact using an LSTM model.

Benefits of technology

This study reveals the adverse effects and spatial evolution patterns of local climate after reservoir impoundment, providing scientific support for the differentiated protection of reservoir ecosystems, quantifying the effects of climate element changes, and supporting the planning, construction, operation, and scheduling of reservoir projects.

Abstract

The application discloses a kind of space differentiation characteristics analysis method and system that reservoir water storage influences local climate in reservoir area, comprising the following steps: determining target reservoir;Collect the meteorological station data in the target area where the target reservoir is located, obtain the environmental factors of target reservoir and each meteorological index before and after water storage of target reservoir;Identify the dominant environmental factor that causes the spatial differentiation of the influence of water storage on local climate;Based on the dominant environmental factor, the improved Theil-Sen trend analysis method is used to determine the influence property of the dominant environmental factor in different partitions;Based on the LSTM model, the specific influence degree of water storage on climate in different partitions is quantified.The application quantifies the change effect of water storage on temperature, precipitation, wind speed, humidity and other climate elements under the premise of stripping the influence of global climate change, and further reveals the spatial differentiation mechanism behind the influence difference.
