中文摘要	采用样带法,以毛乌素沙地南缘牛枝子Lespedeza potaninii-黑沙蒿Artemisia ordosica群落界面为研究对象.以样带上样地间的平方欧氏距离系数为指标,采用游动分割窗技术判定了牛枝子-黑沙蒿群落界面的位置和宽度.结果表明:当分割窗体大小在4个和6个样地单位时,曲线波动大,干扰了界面的判定.而最小窗体大小为8个时,能很好地进行界面的判定.样带A和样带B在样地20～25都出现了波峰.游动分割窗技术是景观界面影响域判定和群落划分的有效方法,并在小尺度研究中能够较好地解释群落水平界面的边界和宽度.
英文摘要	Two transects were set up to study the Lespedeza potaninii-Artemisia ordosica community boundary in south edge of Maowusu Desert. The squared Euclidean distance coefficients of sampling plots along ecotone transect were applied in the moving split-window technique for edge influence of landscape boundary position and width in the area across the community. The result showed that while the split form was in size of 4 and 6 units of plots, the curves dramatically varied and the identification of landscape boundary was interfered. While the minimum size of split-window was 8 plots the landscape boundary could be properly identified. The emerging peaks appeared between plot 20 and plot 25 in Transect A and B. Therefore, moving split-window technique was an effective method for edge influence of landscape boundary and community classification and it was a satisfactory method to show the peaks and widths of communities in small scale.
