托克逊县不同配置防护林的防风蚀特征研究
Research on Anti-wind Erosion Characteristics of Different protection forest in Tuokexun County
[目的]对比分析不同配置防护林的防风蚀效能,为干旱区绿洲城市防沙治沙以及改善生态环境提供理论依据。[方法]以托克逊县城郊防护林为研究对象,通过观测风速,起沙风速,近地表粗糙度,输沙量,风沙流结构等指标,对梭梭林、混交林1(胡杨占68%+柽柳占32%)、混交林2(胡杨占35%+柽柳占65%)进行不同配置林地的防风蚀效能对比研究。[结果]结果表明不同配置防护林的地表粗糙度、起沙风速、风速廓线、防风阻沙效能都有差异。粗糙度随高度的增加而降低,地表粗糙度…查看全部>>
[Objective]To compare and analyze the anti-wind erosion effects of different configurations of shelter forests,to provide a theoretical basis for sand prevention and control in oasis cities in arid areas and to improve the ecological environment.[Method]Taking the shelter forest in the outskirts of Tuokexun County as the research object,a comparative study on the wind erosion prevention efficiency of different allocation forests was carried out on Haloxylon …查看全部>>
