沙漠化土地整治过程中防护林体系优化配置的研究

Study on the Optimal Allocation of Shelterbelt System in the Process of Desertification Land Consolidation

文章对内蒙古鄂尔多斯市达拉特旗五股地沙漠化土地整治过程中防护林体系的优化配置做了研究。结果表明:在沙漠化土地整治和防护林体系配置过程中,应建造控制面积大于6.67 hm^(2)的防护林网,初期在格内设置高立式死沙柳沙障;所选用的树种其生态效益无明显差异,但抗性以新疆杨表现最佳。

This paper studied the optimal allocation of shelterbelt system in the process of desertification land consolidation in Wugudi Village,Dalad Banner,Ordos City,Inner Mongolia.The results showed as follows:in the process of desertification land consolidation and shelterbelt system configuration,a shelterbelt net with a control area greater than 6.67 hm^(2) should be constructed,and high vertical dead sand willow barrier was set up in the grid in the early stage;there was no obvious difference in the ecological benefits of the selected species,but the resistance of Populus alb a var.pyramidalis was the best.
