摘　　要：我国西北地区分布着大量土遗址,在对西北地区土遗址实地调查的基础上,按照病害成因类型对该区域土遗址进行归纳总结。根据调查数据进行量化拟合分析后发现,裂缝、掏蚀、冲沟、倒塌等四种病害之间有明显的内在联系,各种病害形成与发展之间存在先后及促进关系。其中线性拟合结果表明上述四种病害之间呈现不同程度的相关性,裂缝、掏蚀、冲沟等三种病害最终将导致土遗址倒塌,相关系数表明导致土遗址倒塌最为显著的影响因素是土遗址冲沟与掏蚀病害。文章认为土遗址加固保护应该综合考虑多种病害,进行多病害综合治理的方法,最大程度地延缓土遗址破坏。A large number of earthen sites are found in arid and semi-arid regions of Northwest China. Based on the field investigation of earthen sites in Northwest China, this paper summarizes the diseases of these sites in the study area according to the types of disease causes. The quantitative fitting analysis of survey data revealed an internal relationship between four typical diseases, namely cracks, erosion, gullies, and collapse, and a sequence and promotion relationship between the formation and development of various diseases. Linear fitting results show a positive correlation among the four aforementioned diseases in varying degrees;cracks, erosion, and gullies will eventually lead to the collapse of earthen sites. The correction coefficient indicates that the most significant factors leading to the collapse of earthen sites are the development of gullies and erosion. Thus, the reinforcement and protection of earthen sites should consider a variety of diseases, and comprehensive treatment of multiple diseases should be performed to delay the destruction of earthen sites to the largest extent.
