Study on Deterioration and Conservation of Sukhothai Historic Site, Thailand

1-通过在SRI Sawai寺庙设置计算机控制的测量系统来测量Sukhothai历史遗址的环境条件。还测量了室真寺大殿内部的微气候。利用测量得到的数据，对大殿内大佛保护遮蔽物的效果进行了模拟分析。研究表明，在大殿上设置遮蔽物是有效的。2--利用两尊老佛像进行了实验研究。一座是室真寺大殿旁的中型佛像。另一尊是萨斯寺的同型佛像。两座雕像都被清洗过。然后，对萨斯寺的雕像进行了硅树脂溶液浸渍处理，而室真寺的雕像没有进行处理，而是覆盖了侧开式茅草屋顶。对这两尊雕像的定期调查表明，这样的避难所对雕像的保护是有效的。3-一种新型的杀菌剂，以消除藻类、地衣和苔藓，在斯里钦寺和萨斯寺进行了测试。4.对素可泰历史遗址过去所做的保护工作进行了现场和文献调查。5-在其他类似遗址，如大城府遗址、吴哥遗址(柬埔寨)、我儿子遗址(越南)等进行了比较研究。

1- Environmental Conditions of Sukhothai historic site were measured by setting a computer controlled measuring system at Sri Sawai temple. Micro-climate of the inside of the main hall of Sri Chum temple was also measured. Using the data obtained by those measurements, simulation analysis was done on the effect of a shelter on the hall for preservation of Giant Buddha in the hall. And, it reveals that setting a shelter on the main hall is effective.2-An experimental study using two old Buddha statues was conducted. One is a middle size Buddha statue next to the main hall of Sri Chum temple. The other one is the same type Buddha statue in Sa Si temple. Both of two statues were cleaned. Then, the statue at Sa Si temple was treated by impregnation with silicone resin solution, while the statue at Sri Chum temple was not treated but covered with a side-open type thatch roof. Periodical investigation of those two statues reveals that such a shelter is effective to preserve the statue.3-A new type biocide to eliminate algae, lichens and mosses was tested at Sri Chum temple and Sa Si temple. And, it reveals that the new type biocide is very effective.4-The past conservation works done at Sukhothai historic site were investigated in situ and in documents.5- Comparative studies were done at other similar sites such as Ayutthaya site, Angkor site (Cambodia), My Son site (Viet Nam) etc.,.
