Provided is a method for configuring slope regulation and storage measures based on flood regulation and storage capacity and water consumption control, including the following steps: S, collecting and organizing precipitation data of a basin; S, constructing an optimized configuration model based on a balance between flood regulation and storage capacity improvement and slope water consumption control; S, initializing settings; S, computing an optimal comprehensive benefit of the slope regulation and storage measures with a genetic algorithm; and S, determining whether a number of iterations is maximized; if the number of iterations is maximized, terminating an iteration and outputting data, such that a computation is completed; and if the number of iterations is not maximized, returning to the S, and restarting the computation. The optimized configuration model of this application can resolve a balanced relationship between flood regulation and storage capacity improvement and slope water consumption control.

The present disclosure provides a field integrated device for automatically shielding and collecting rainwater and simulating rainfall and an experimental method. The field integrated device comprises a roller shutter assembly. A rainfall assembly and a rainwater collecting assembly are fixed on the roller shutter assembly. The roller shutter assembly guides rainwater into the rainwater collecting assembly while shielding the rainwater. The rainfall assembly is connected with a pumping assembly. The pumping assembly transports the rainwater to the rainfall assembly to realize artificial rainfall simulation. The pumping assembly is fixed in a solar module. The solar module is electrically connected with the pumping assembly and a driving assembly in the roller shutter assembly. The solar module is in signal connection with a remote signal end.

The present invention discloses a method for detecting glacier melting based on tracer technology. The method includes the following steps. 1. Different tracer agents with equal concentration are respectively added into a plurality of water samples. The water sample and the tracer agents are mixed well. Meanwhile, the volume and the mass of each glacier model are recorded. A plurality of water samples added with tracer agents are frozen layer by layer from inside to outside to establish a plurality of glacier models. 2. The surrounding environmental factors of the glacier model are adjusted. Water samples of the glacier models melted under different environmental factor conditions are collected. Furthermore, the concentrations of different kinds of tracer agents in the water samples are measured.
