西北干旱地区由于其独特的地理环境和气候特征,成为我国受风沙侵蚀最严重的地区。基于此,首先对西北干旱地区进行概述,接着通过某林区的3片植被种类不同的区域进行标准地调查、防风圈沙效应固定和土壤成分方面的分析,认为多层次、多样化、网格状的防风固沙林的防护效果最好。林业的发展不仅对防风固沙有重要作用,还能够改善土壤成分,帮助重建健康的生态系统。
Due to its unique geographical and climatic characteristics, arid regions in northwest China have become the most affected areas in our country. Based on this, we first outline the arid areas in northwestern China, and then conduct a standard survey on three types of vegetation in different areas of a certain forest area, and analyze the effect of wind-sand suppression and soil composition. We believe that the multi-level and diversified grids Sand-shaped sand-shaped protective effect of the best. The development of forestry not only plays an important role in windbreak and sand fixation, but also improves soil composition and helps rebuild a healthy ecosystem.
