| 摘 要： | 选取位于贵州省普定县的后寨地下河流域中下游作为研究区,利用地理信息系统软件,解译出研究区2004年的潜在石漠化等级分布图,对海拔、坡度、坡向和坡位等地形因子同各等级潜在石漠化景观面积的相关关系进行定量分析。结果显示,研究区潜在石漠化景观在空间上呈不均匀分布;海拔、坡度和坡向等地形因子同潜在石漠化景观的多个等级斑块面积之间相关性显著(P<0.05或P<0.01);随着海拔的增加,低度和中度潜在石漠化面积所占比例逐渐增加,无石漠化和极低度潜在石漠化面积所占比例逐渐减少;随坡度的增加,无石漠化面积所占比例逐渐减少,低度、中度及极高度潜在石漠化面积所占比例逐渐增加;随着坡向由阴转阳,中度和高度潜在石漠化面积所占比例逐渐增加;而坡位与各等级潜在石漠化景观面积之间无显著相关性。 |

| Abstract: | To explore distribution of potential rocky desertification and their relationship with topographic factors,the middle and lower reaches of the Houzhai subsurface stream in Puding County was chosen as a study area.With the aid of GIS software,the 2004 potential rocky desertification distribution map was studied to analyze quantitatively correlation of topographic factors,such as elevation,slope,exposure and position,with areas of rocky desertification.Results show that potential rocky desertification distrib... |
