摘要:
 以裸露砒砂岩区鲍家沟小流域为对象，运用景观生态学理论和典型相关分析相结合的方法，研究了裸露砒砂岩区小流域土壤侵蚀空间自相关特征及影响因素。结果表明：1）以鲍家沟小流域为代表的裸露砒砂岩区典型流域，流域内的优势景观为裸露基岩景观，其次为连片的人工植被景观。2)各斑块类型的破碎程度呈草地>山杏林>柠条林>油松林>沙棘林>裸露基岩的排列顺序。3)典型相关分析表明，流域植被景观格局具有零散和形状复杂的斑块特征，坡度和地表切割深度是导致植被景观破碎并决定景观空间分布格局的主导因素。研究裸露砒砂岩区小流域植被景观空间格局与地形关系，对于科学指导区域植被建设，减轻入黄泥沙有重要意义。
Abstract:
 The exposed feldspathic sandstone region is one of the main coarse sand source regions in the middle reaches of the Yellow River.Studying the relationship between spatial pattern of vegetation landscape and topography has great significance to guide vegetation construction and reduce the input of coarse sand into the Yellow River.In this research,through theory of landscape ecology and canonical correlation analysis,we studied the relationship between spatial pattern of vegetation landscape and topography in Baojiagou watershed of exposed feldspathic sandstone region.The results showed that 1) Baojiagou watershed was the most typical one among the feldspathic sandstone regions.The dominant landscape in the the watershed was exposed bedrock,followed by a large area of artificial vegetation landscape.2) The degree of fragmentation of spatial pattern of vegetation landscape patches was in the order of grass land>Prunus armeniaca>Caragana korshinskii>Pinus tabulaeformis>Hippophae rhamnoides>bare land.3) Canonical correlation analysis presented that the vegetation landscape pattern had scattered and complicated shapes of patch characteristics.Slope and surface cutting depth were the main factors leading to the fragmentation of vegetation landscape.
