摘要
土地沙化是我国当前最为严重的生态问题,沙障作为防沙治沙的主要措施之一,在我国干旱沙区发挥了重要作用。在流动沙丘上布设埋嵌式塑料网带状沙障,能阻截近地面风沙流和增加植被覆盖度,具有良好的固沙效益。和黏土沙障、麦草方格沙障、塑料网方格沙障相比,埋嵌式塑料网带状沙障具有材料运输方便、操作技术简单、投入成本低、防护时效长、便于机械化操作、省时省力等优点,推广应用前景广阔。
The most serious ecological problem in our country is land desertification.The sand barrier is one of the main measures to prevent and control desertification which has played an important role in arid desert areas of China.Laying embedded plastic banding sand-barrier on moving dunes can intercept the surface sand flow,increase vegetation coverage and has good sand fixing effects.Comparing with clay sand-barrier,straw grid sand-barrier and plastic checkerboard sand-barrier,the embedded plastic banding sand-barrier has the advantages of easy transportation of material,simple operation,low cost,long protective aging,convenient mechanized operation and saving time and labor.Therefore,it has broad prospects for popularization and application.
