Rain, snow and other pollutants absorption pores on materials and cause façade erosion; this process in porosity materials is quickly, as moisture with glacial and microbiologic effect compromising durability materials.
That happed for eliminate surface exacerbation moisture penetration into fabric materials.
Only Hardy Materials Work Water Penetration into Cracks and Erosion is possible.

Countries in the process of Eco-tourism development should work closely with ecological tourist destination, provide assistance and support for Eco-tourism development: (1) Develop Eco-tourism related standards, specifications of ecotourism planning process;(2) Develop scientific study, research and evaluation services of ecological tourism resources; (3) Provide classification and evaluation services to the ecological tourist resources ; (4) Provide relevant ecological tourist development planning services; (5) Provide supporting services for the ecological tourist area of merchants; (6)Provide related services of science and technology for the Eco-tourism development; (7) Assist the community to cultivate the training services of local managers and tour guides.
Buildings and decoration in the Scenic area use local materials, don't use a wide range of foreign building materials, it is not only environmentally friendly but also can make its background environmental photograph harmony with the scenic spot, and it has the very high value of environmental education.
