Abstract：After a lot of site investigations，analyses and tests in the laboratory，it is found that the earthen ruin sites now existing in the arid regions of northwestern China have multi-diseases，which mainly take the forms of the backoff of wall bases，holes or cancellations，scaling off，cracks and collapses. All these diseases mentioned above are caused by wind erosion，rainfall erosion and repeated eutectic salt dissolving. This finding will play an important part in guiding us to protect the earthen sites in the areas concerned.
