      abstract = {Based on geographical differences and space  differentiation, valley economy is a new pattern and new  perspective for the development of mountainous areas,  integrating ecological protection, industrial nurture, and  village integration. On the basis of natural and  geographical differentiation of valley, we give an overview  of the spatial distribution of valley in mountainous areas  of Beijing and spatial difference in valley density, and  sum up the typical development pattern of valley economy,  using DEM data. The results show that the spatial  distribution of valley presents an asymmetric shape of  inverted V or branch; Miyun, Yanqing, and Changping have  great valley density, while Pinggu, Fangshan and Mentougou  have small valley density; there is a significant positive  relationship between valley density and the spatial  distribution of river, reservoir. The development pattern  of valley economy is divided into five types: leisure and  high-end upgrade-based pattern, ecological development and  transition demonstration-based pattern, folk culture and  creation-driven pattern, scenic spots-driven and  valley-linked pattern and leisure agriculture and  specialty-led pattern.},
