Abstract:Vertical planning is the special support of the control and regulation level and is the basis of the implementation planning of mountainous and hilly cities. Based on the characteristics of mountainous and hilly cities, the principles and strategies of vertical planning of chemical parks are put forward. The vertical planning methods of chemical parks in mountainous and hilly cities are analyzed and studied from four aspects of vertical planning of roads, vertical planning of sites, drainage planning and earthwork balance, and the essentials for attention in the vertical planning process are sorted out and summarized. In the recent construction of the park, it is expected to directly guide the design of project construction drawings, effectively reduce the external transportation of earthwork, maximize the earthwork balance and reduce the government investment.
