The invention provides a rain collection and snow-melting agent resistance device for anti-glaring trees in a central isolation zone of an express way. Rolling traces are formed between a first rain collection plate and a first rain collection and snow-melting agent resistance turning plate, a second rain collection plate and a second rain collection and snow-melting agent resistance turning plate, a third rain collection plate and a third rain collection and snow-melting agent resistance turning plate and a fourth rain collection plate and a fourth rain collection and snow-melting agent resistance turning plate. As the rain collection plates are paved in the central isolation zone of the express way, rain on the central isolation zone is collected into green tree-planting pool to be irrigated; therefore, by the mode, the natural falling water can be used fully and the rain collection efficiency is high; the rain collection plates can also be used for preventing water in soil of the central isolation zone from being evaporated and preventing weeds from growing, so that the weed removal maintenance working quantity of the central isolation zone of the express way can be reduced. The rain collection and snow-melting agent resistance turning plates are turned up in winter and placed down in spring; the rain collection and snow-melting agent resistance turning plates and the rain collection plates are connected into a whole, so that the occupied area is small and snow-melting agent snow water on the road can be effectively prevented from sputtering into the green tree-plantingpool.
