Zusammenfassung:The invention discloses a lake buffer zone building method for non-point source pollution control. The method includes the following steps that a region among a farmland, a village and a lake is selected to serve as the foundation to build a buffer zone. The buffer zone comprises a vegetational zone (1) planted with indigenous plants (3). The end, away from the lake, of the vegetational zone (1) is the front end, and a reinforcement substrate zone (2) is built at the front end or the middle of the vegetational zone (1). The lake buffer zone building method for non-point source pollution control which is good in purifying effect, easy to operate and low in cost is provided for control over non-point source pollution and particularly control over nitrogen and phosphorus in the non-point source pollution.
