  1. Notes: Grasslands are mainly distributed in areas with elevations below 3,000 m and are strongly interfered by human activities and thus were assigned a naturalness value of 3. As for some large lakes and rivers such as Erhai Lake, Lugu Lake, Dulong-Irrawaddy and Nu-Salween, they were scored by adopting the national water quality standards and the better the water quality was, the higher they were scored. The water quality data were derived from the “2013 annual bulletin of environmental conditions in Yunnan Province”36. In terms of some unnamed plateau lakes, those located in areas with elevations above 4,000 m were assigned a value of 5, while lakes located below elevations of 4,000 m were assigned with value 3.
