Plant community construction method capable of cutting pollutant output from lakeside fallow area

The invention relates to a plant community construction method capable of cutting pollutant output from lakeside fallow area. Three different types of plant community construction techniques are used, output values of runoff pollutant monitored the method of standard runoff plot in 2 years are analyzed, and three kinds of lakeside communities are used to construct. The three kinds of lakeside communities comprises: (1) shrub-arbor-grass plant community; (2) shrub-grass plant community; (3) shrub-grass spontaneous recovery plant communities. The plant community construction method has advantages that (1), combining ecological engineering, environmental engineering and landscape effect is economical and effective; (2) the community structure is reasonable with bearing impact load, and can adapt to the impact of unexpected events such as the southern untimed rainstorm on lakeside zone; (3) species selection is feasible and scientific. 本发明涉及种能削减湖滨退耕区污染物输出的植物群落构建方法，通过3种不同类型植物群落构建技术，采用标准径流小区监测2年的径流污染物输出值比较分析，采用3种湖滨
