During the pre-test period (November 11-16, 2007), according to the topographic characteristics of Binggou basin, a total of 51 flower stems were arranged according to different topographic distributions such as flat land, shady slope, sunny slope and semi shady slope (including morning sunny and afternoon sunny), and the height of each flower stem was 2 meters. The height of each flower stem exposed outside the surface was recorded. During the enhanced test period (from March 2 to April 6, 2008), 10 flower stem observations were carried out in Binggou basin to observe the exposed height of flower stems after snow cover, and the snow depth at flower stems was obtained by calculating the difference with the height of bare land.\n
\nThe flower stem observation adopts two methods: human close-up observation and telescope assisted observation, accurate to cm. There were 10 observations in the test period in 2008.
