The invention discloses a method for collecting climate change information and water resource information. The method comprises the following steps: weather information and target water source information near a target water source by a terminal based on Internet of Things communication are acquired; the terminal based on Internet of Things communication sends reverse link data to the first transmission receiving point; the terminal based on the Internet of Things communication measures a first link quality represented by a signal to interference plus noise ratio between the terminal based onthe Internet of Things communication and the first transmission receiving point and a second link quality represented by a signal to interference plus noise ratio between the terminal based on the Internet of Things communication and the second transmission receiving point; the terminal based on the Internet of Things communication judges whether the second link quality represented by the signal to interference plus noise ratio is superior to the first link quality represented by the signal to interference plus noise ratio or not; and if the link quality is superior to the first link quality represented by the SINR, the terminal based on the Internet of Things communication sends a reverse link data transmission report to a second transmission receiving point.
