- Abstract:
- The tree spatial structure and the wind break function are studied on psammophyte,such as Holoxylom ammodendron Bunge,Hedysarum scoparium Fiseh.et Mey,Caragana korshinskii Kom and Calligonum mongolicum Turcz which are desertification control afforestation trees.The results showed that the total number of branch,the number of branch which have the diameter between 0～2,2～4,4～6,6～8,8～10 mm,the windward side width are increasing with the tree height,and when reach the maximum,then reduced.The number of branches whose diameter above on 10 mm declined.The four psammophyte all have the function of weakening wind speed,but the function gradually reduced with the increasing of the distance behind tree.The wind break function has a correlation with barrier side and windward side width.There is a positive correlation between windward side width and barrier side width.
