By adopting an ecological ditch technology, a plurality of plants are arranged in the ditch to intercept and adsorb substances such as nitrogen, phosphorus and the like in the ditch water body, and the nitrogen and phosphorus pollutants are purified and treated by utilizing the combined action of physics, chemistry and biology, so that part of pollutants are blocked from entering the water body, and the aim of reducing the pollution is achieved. (3) Terminal reinforcement: the tail end of the surface source pollution path is used for accommodating water, and ecological restoration measures can be adopted for carrying out the tail end pollutant reinforced absorption, so that the pollutant entering river is reduced. The ecological restoration measures adopted by the general river and the lake comprise the arrangement of an ecological slope protection buffer belt at the bank side of the river and the lake, the arrangement of a front-mounted reservoir at the front end of the lake reservoir, the ecological wetland technology, the construction of aquatic animal and plant communities and the like.

For the process blocking technology, plants can be planted only in ditches with natural soil, and most of the ditches are reconstructed concrete ditches, so that plants cannot be planted. In autumn and winter, plants wither and cannot play the role. Moreover, for the terminal strengthening technology, another piece of land needs to be searched to construct an ecological wetland or a buffer zone, so that land resources are scarce, and not every place can be provided with the place for terminal treatment, so that the terminal treatment has defects.
