| 摘 要： | 本文重点对晋陕蒙砒砂岩区沙棘生态工程实施前一年（1998年）、中期（2003年）、最后一年(2008年)3个控制年份,通过专用软件,分类型统计各景观要素的面积、斑块数等,对区域内景观成分组成结构进行了分析.砒砂岩区在沙棘及其他生态工程建设的实施基础上,区域景观格局发生了很大变化,景观本底由盖沙地和稀疏植被分庭抗衡,逐渐过渡到以稀疏植被、灌丛、林地和沙棘等各类植被为主.沙棘渐渐成为区域景观的重要组成部分,对区域生态环境改善起着越来越重要的作用.

| Abstract: | The areas and numbers of different patches,and then the structure of the landscape types have been calculated through special software to the seabuckthorn project in the Soft Sandstone Area from 1998（one year before the begin year）,2003（middle year）,2008（the finish year）.The matrix in the area has been changed from sand and open vegetation before the projects of seabuckthorn and other ecological engineering to open vegetation,shrub,forest and seabuckthorn after the projects.Great changes have been taken place in the area for the landscape pattern,that seabuckthorn has gradually been the important types in the area to play a powerful role for environment improvement. |
