- Title:
- Evaluation of Landscape Pattern after Seabuckthorn Planting in Soft Sandstone Area
- Keywords:
- soft sandstone area (SSA); Hippophae rhamnoides; landscape; principal component analysis (PCA); cluster analysis

- 摘要:
- 通过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个控制年份斑块特征的分析，发现作为景观主要组成部分的稀疏植被、草地、灌丛、沙棘和林地陆续增加，而未利用地和盖沙地面积继续下降。景观生态整体继续向植被面积更大、分布更为合理的方向发展，这也是实施沙棘生态工程的主要目的所在。
- Abstract:
- The patch characteristics have been studied in the Hippophae rhamnoides project through the methods of principal component analysis (PCA) and cluster analysis in the Soft Sandstone Area (SSA) from 1998 (one year before the begin year), 2003 (middle year), 2008 (the finish year), which showed that the main forms of landscape in the area like open vegetation, grassland, shrub, Hippophae rhamnoides and forest, had been gradually increasing while unused and sand decreasing. The total landscape system continuously develops into more vegetation coverage, more reasonable distribution, which is the main purpose of the Hippophae rhamnoides project.
