摘要
利用CCA、DCCA等多元分析方法,在景观尺度上对山西高原植被与土壤分布格局之间的关系进行了分析,所得结论表明:纬向上主要是栗褐土、褐土、风沙土和栗钙土与植被的变化格局相关性较强,由于山西高原南北跨度大,土壤和植被格局纬向变化趋势的一致性十分明显;黄绵土、栗钙土、山地草甸土与植被的经向分布格局密切相关,由于山西高原东西向跨度较小,且大部分地区处于吕梁山与太行山之间,植被和土壤的经向格局梯度不明显;随海拔高度的增加,棕壤、山地草甸土、亚高山草甸土与山西高原植被的垂直分布格局相平行,由于山西高原相对高差较大,这种趋势也非常明显。综合分析还表明了气候、土壤与植被格局的一致性。
Relationships between vegetation and soil in Shanxi Plateau were studied using detrended canonical correspondence analysis (DCCA).It is shown that the first DCCA axe represented the diversity of vegetation and soil along latitude in Shanxi Plateau.The vegetation types and their distribution along latitude were mainly correlated with grey cinnamon forest soil,cinnamon soil, aeolian sandy soil and chestnut soil. The second DCCA axe represented the diversity of vegetation and soil along longitude in Shanxi Plateau. The vegetation types and their distribution in this direction were mainly related with loessal soil,chestnut soil and mountain meadow soil. Because Shanxi Plateau has a long latitude and a short longitude, the change of vegetation and soil along latitude is much greater than that along longitude. The third DCCA axe illustrated the vertical diversity of vegetation and soil along altitude, the vegetation types and their distribution were closely related with brown forest soil, mountain meadow soil and subalpine meadow soil.
