Method for constructing cold region riparian buffer zone for preventing and controlling agricultural non-point source pollution
The invention is applicable to the technical field of ecological engineering, and provides a method for constructing a riverbank buffer zone for preventing and controlling agricultural non-point source pollution in a cold region, which comprises the following steps: step 1, trimming a riverbank side zone; 2, sequentially planting arbors, shrubs and herbaceous plants in the river shoreside zone; 3, an AMF fungicide is applied in the gradual freezing period and the spring thawing period; and 4, daily maintenance and management are conducted on the ecological buffer zone. After the riparian buffer zone is constructed, the vegetation coverage of the riparian zone is improved to 95% or above; the non-point source pollution interception effect is good, the load of pollutants such as TN and TP is reduced by 50% or above, the biodiversity of a shoreside zone is remarkably improved, soil erosion is effectively prevented, and water eutrophication is effectively prevented.
本发明适用于生态工程技术领域，提供了一种构建阻控农业面源污染寒冷地区河岸缓冲带的方法，包括以下步骤：步骤一、修整河流岸边带；步骤二、在河流岸边带依次种植乔木、灌木、草本植物；步骤三、在渐冻期和春融期施用AMF菌剂；步骤四、对生态缓冲带进行日常养护及管理。本发明河岸缓冲带构建完成后，岸边带植被覆盖度提高到95%以上；对面源污染截留效果好，TN、TP等污染物削减负荷50%以上，岸边带的生物多样性显著提高，有效防止土壤侵蚀，有效预防水体富营养化的发生。
