The utility model relates to an ecological bank protection that can be used to hydrological experiment monitoring, divide the ecological bank protection of road (7) or river course both sides into a plurality of landmass, every landmass sets up the different slopes and covers with different vegetation, lay on every landmass respectively hyetometer (8), evaporating dish (9), flowmeter (12), soil moisture sensor (11) and warm and humid acidimeter (10) one or more, hydrological element data under its different situation who collects, a hydrologic analysis research for going on under the change underlying surface condition. The utility model discloses not enough to hydrological element data data acquisition under the present change underlying surface condition with the help of present ecological bank protection theory, improves it, can carry out the collection of hydrological element monitoring data under the different natural condition in field.
