  • 简介:山谷经济是在被山谷开发的各种各样的人物定义的多山的区域开发的一个新模式,并且是区分为多山的区域开发的节俭的地理模式。在在山谷的不同多山的元素的分发的特殊空间联合关系是为山发展研究的新题目,并且如此的研究为研究和惯例两个都是有意义的。把简短探索基于关于多山的区域开发和追随者的长期的研究进涵义和山谷经济的空间组织进程,作者在北京多山的区域分析了山谷经济的开发的现在的状况,在北京多山的区域学习了特征和山谷经济的空间结构的变化的影响,并且最后建议了山谷经济的空间结构的合理安排山谷经济在新时代在北京多山的区域在发展和功能的转变起一个重要作用,这在这研究被考虑。第一,山谷经济没被行政边界构画出,并且它沿着主要交通线粗略地在多山的区域连接大多数村庄。因此,山谷经济能在多山的区域对发展施加积极影响,至少在象在多山的区域和农村、城市的区域的协调发展的工业结构的重新整理那样的方面。另外,在北京多山的区域的山谷经济在第二等的集中的一个空间组织阶段被发展,这被发现,它被节省资源的、生态的保护和工业优化描绘。因此,山谷经济的发展将在多山的区域对在生态的保护和经济开发之间的协作有用,并且将支持多山的区域的综合发展。在北京多山的区域的山谷经济的发展中的模式将在北京多山的区域的功能的角色的转变为决策提供基础,并且在另一方面,将在北京外面在多山的区域为研究介绍经验。
