Blocks of traditional revetment have simple structure and single function, and traditional revetment has a negative effect on the environment for years. In order to improve this situation, based on the experimental study on the selectivity of fish towards the pore, I redesigned the block of ecological revetment. And I have been designed the porous ecological revetment block. The new block of revetment has many big pores, and fishes swim around it and live in it; pore of plant growth provides a space for growing aquatic plant; in order to guarantee stability of the blocks, the article designs the embedded structure, it diversifies the connection of blocks to accommodate a variety of terrains. Through the stability analysis of porous ecological revetment block, three design sizes of block that meet the stability requirements was defined.
