"Fairy Tale World," "fairyland on earth" and known for Jiuzhaigou at longitude 103 ° 46 '-104 ° 4', latitude 32 ° 51 '-33 ° 19', Aba Prefecture in Sichuan Province in the northwest county of Jiuzhaigou, and Department southeast edge of the Qinghai-Tibet Plateau Ga Thurner at the northern foot peaks, at an elevation of 2000-3000 m, from the Sichuan provincial capital Chengdu, 435 km. Jiuzhaigou ditch and north to south, the terrain gradually increased, if the vertical section of a cut-shun Valley, this increased show is like a ladder. This is because the strong rise in the Qinghai-Tibet Plateau, which formed the edge of the different levels of the ladder-like block, the block in the Jiuzhaigou one of the main northern West to the new structure for the fracture sector, the main falls, such as Jiuzhaigou Shu Zheng, Connaught Long day, Pearl Beach, Xiong Maohai, and so is the development of these faults caused by the terrain on the order Hom. As the Department Hom in order to form water or water pressure to reduce in-house, the water is conducive to the CO2 escape, and promote the precipitation of travertine, travertine made in the Hom-order or the accumulation of water is continuously growing, forming a spectacular travertine. Lake connotations cause of the lake due to the scattering of sunlight, reflection and absorption. Sunlight or natural light is monochromatic light of different wavelengths combination of polychromatic light in the spectrum, from violet to red light, the wavelength decreases. Jiuzhaigou's a beautiful lake of blue and green on the lake Zhongduan Bo long scattering length is much larger than the wavelength, this is the Rayleigh scattering (RAYLEIGHSCATTERING) effect. Rayleigh scattering effect in the lake in Jiuzhaigou was particularly promine
