围封对阿尔乡沙化区域生态恢复潜力综合评价

阿尔乡与内蒙古科左后旗相毗邻,是科尔沁沙地南缘的一部分。随着人类过度的放牧和不合理的土地利用,土地沙化现象愈演愈烈,围栏封育以其投资少,易实施的特点成为治理沙化现象的主要措施。本文以阿尔乡围封的沙化土地为研究区域,运用恢复生态学、植物生态学和土壤学等多学科理论,通过野外调查、室内试验及数据统计分析等多种手段,运用综合指数法对生态恢复潜力进行综合评价,证实了围栏封育对阿尔乡沙化区域的生态恢复效应显著,揭示了围栏封育对该区域生态恢复的潜力。

Aer Desert of Zhangwu country adjoins Kc Zuohouqi of Mongolia, Aer Desert is a part of the south the Horqin sandy land. With human over-grazing and not reasonable land use, desertification phenomenon is increasing fierce. Enclosing is management measure of desertification due to low cost and easy operation. This study is based on the research of which is enclosed, using restoration ecology, plant ecology and soil science to evaluate the potential of ecological restoration for enclosing by using comprehensive index method, through the comprehensive evaluation of ecological recovery potential, it is confirmed that the ecological restoration effect is significantly after enclosing. The result show that ecological recovery is potential by enclosing.
