Basic Characteristics of Windbreak in the Black Soil Region of Northeast China and Its Relationship with Wind Direction
摘要
Abstract
[Objective]In order to explore the relationship between the windbreak direction and the prevailing wind erosion direction in the black soil region of Northeast China.[Methods]The basic characteristics of the windbreak in the study area were obtained by remote sensing interpretation and field survey,and the angle of intersection between the windbreak direction and the prevailing wind erosion direction,that is,the wind direction declination angle,was calculated and analyzed by combining the wind speed and wind direction data of 43 meteorological stations in the study area.[Results]The westerly wind in Mengdong black soil sub-region accounted for a large proportion,the wind direction was more concentrated,the prevailing wind erosion direction dominance was strong,the wind direction in the Songnen black soil sub-region was scattered,and the prevailing wind erosion direction dominance was weak.Average windbreak density Songnen black soil sub-area＞Mengdong black soil sub-region;The windbreak direction accounted for the largest proportion in the Songnen black soil sub-area was the N-S trend windbreak direction,and there was no obvious regularity in the Mengdong black soil sub-region.In the study area,the proportion of wind declination angle＜30° was 29.60％,and the proportion of wind angle＞30° was 70.40％,and the wind protection effect was poor.[Conclusion]The direction of a large number of windbreak in the study area is oblique to the prevailing wind erosion direction,and the protective effect is poor.The results of this study have important reference value for understanding the density and trend of existing windbreak belts,and for further construction and transformation of windbreak.关键词
