Abstract:: Through field test observations, this paper made a comparative analysis of the windproof performance of farmland shelterbelt in different types and structure. Optimal allocation recommendations of shelterbelts are proposed on this basis. The results show that windproof effects decrease in the order sparse transparent farmland shelterbelts > ventilated farmland shelterbelts > compact shelterbelt forest; In the vertical direction, the three kind sparse transparent tree shelterbelts at different heights generally follow this trend of increase of wind with height performance gradual downward. The average wind performance of mixed shrubs and bushes shelterbelts is elm + caragana shrubs mixed with 21.5% > 20.5% shrub shelter belts. The effective protection distance for wind reduction by 20% appeared at Corinthians 25H and 12H. Shelterbelt construction should be the preferred mixed shrubs; shrub shelterbelts can be laid in serious desertification of cropland or outlet strip of farmland; tree shelterbelts are not the best choice.
