Ecological slope protection building block and building block combination

The utility model discloses an ecological slope protection building block and a building block combination, belongs to the field of municipal engineering, and solves the problems of integral slippage and local slippage in the building block construction process. An ecological slope protection building block comprises a building head and a building tail which are connected, the lower surface of the building head is horizontal, the upper surface of the building head is inclined, the end, close to the building tail, of the building head is high, the building tail is in an inclined plate shape, the upper surface of the building tail and the upper surface of the building head are smoothly connected along the same inclination, and the building head can be contained in the bottom space of the building tail. An ecological slope protection building block combination is formed by arranging a plurality of ecological slope protection building blocks in a linear mode, the building head of the rear building block is locate
