China is a mountainous country, with hills, mountains, and plateaus cover about two-thirds of its total land area. The vast area, huge population, rich natural resources, and great potential of development in mountain areas make them the most important “rear garden” supporting the sustainable development of the whole country. Nevertheless, China’s mountain areas are also prone to various kinds of natural disasters, and thus formed a scenario of high overlap between the high-risk zone of natural disasters and the lagging zone of social and economic development. And such scenario has caused significant waste of various related inputs, and becoming a …
