中文摘要：

分析了沟域经济的内涵及其对山区发展战略的影响，提出了“廊道＋沟域＋节点”的山区空间发展战略模式。以门头沟区为例，其沟域经济发展模式可归纳为“走廊带沟域促节点”，这符合提出的山区空间发展战略模式。交通线是沟域经济发展的主要廊道，在空间上打破了传统行政上的界限；沟域是沟域经济发展的主阵地，是山区发展的最佳区域；村庄是山区发展的主要节点，通过集聚式发展，符合山区发展空间优化的原则。

英文摘要：

Valley economy, as a new mode of mountain development, is playing an important role in gathering and effective linking the space of mountain traffic, villages, population and resources in order to meet the requirements of mountain space optimization development. Mountains spatial development strategy is the overall consideration of spatial layout on valley economy development. Based on the correlation between valley economy development and mountains spatial development strategy, the paper employs the methods of documentation and systematic analysis, studies the spatial development strategy of mountain under the background of valley economy, and proposes the spatial development strategy of ＂corridor ＋ valley ＋ node＂ to mountain areas. The authors provide a case study of Mentougou district. They summarize its valley economy development mode as ＂corridor construction spurs the development of valley economy＂, in which the authors take G108 and G109 as corridor axis, and 18 key valleys as the grasps for the improvement and optimization of the various types of villages. This is consistent with the proposed spatial development strategy of mountains areas. Traffic lines, the main corridors for the development of valley economy, break the limitation of traditional administrative in space of land use. Valleys are the main front of valley economy development, as well as the best region of mountain development. Villages, the main nodes of mountain development, promote the cluster development of valley economy spontaneously, which fits the principle of further optimization of mountain in spatial. Valley economy development exerts a systematic impact on implementing mountain spatial development strategies by taking the drainage basin as an unit and an overall consideration of ecological development, economic development, social development, cultural training.
