.
The agricultural non-point source pollution ecological prevention and control plant community constructed by the invention can effectively increase the surface runoff time by 1.
1-1.
5 times, and can reduce suspended solids by 46.
3-65.
7% , The total nitrogen content is 41.
8-20.
3% , and the total phosphorus content is 22.
6-30.
9% , which can effectively prevent and control non-point source pollution.
At the same time, it has good landscape aesthetic function and obvious ecological benefits
