【摘要】 西北地区尤其丝绸之路沿线是中国土遗址分布最多的地区,其土遗址分布集中,种类多,赋存环境复杂,具有炎热、年较差和日较差较大、干燥少雨、偶有极端降雨气候,大风、沙尘暴经常发生,构造活动剧烈和地震频繁等特点.土遗址的病害类型多,基本包括了干旱环境土遗址的所有病害.西北地区室外遗址主要病害是片状剥离、风力淘蚀和裂隙;室内土遗址的主要病害是污染、温度剥离和裂隙.土遗址的病害受赋存环境和土遗址本身的特性两方面控制,影响西北地区土遗址病害的环境因素主要是风、雨和地震.更多还原

【Abstract】 The earthen sites in China are distributed in the northwestern region mostly,especially along the Silk Road.The distribution is centralized,and the type of earthen sites is diverse;and also,the environment of earthen sites is complicated.There are many types of the earthen sites diseases,basically including all of the earthen sites diseases of arid area.The main diseases of outdoor sites in northwest China are spin-off sheet,wind erosion and fracture,while the main diseases of indoor sites are pollution,temperature spin-off and fracture.The diseases of earthen sites are controlled by environmental occurrence and their own characteristics.The environmental factors which account for the earthen sites diseases in northwestern region are mainly wind,rain and earthquake.更多还原
