| 摘 要： | 在绿洲边缘及内部营造农田防护林最重要的作用是降低风速、控制农田土壤风蚀、防止或减轻地表起沙和风沙入侵，为农业生产营造一个良好的生产环境。绿洲农田防护林是绿洲防风阻沙、控制风蚀必不可少的技术措施之一，对农业生产具有重要意义。本文通过定位观测实验与定量分析相结合的研究方法，对不同结构类型的防护林防风阻沙的基本规律及防护效益进行了研究。

| Abstract: | Inside the oasis and around the edge of the oasis,the most important function of farmland shelterbelt is to build a friendly producing environment by decelerating wind velocity,controlling soil wind erosion,and defending or abating wind-sand intrusion.Oasis farmland shelterbelt is rather important in agricultural production,which is one of the necessary measures to defend wind and control wind erosion.In this paper,located observation and quantitative analysis are combined to analyze the basic rules and pre... |
