Mountain village and town public service facility layout method and system based on service isochronous circle

Abstract

The invention discloses a mountain village and town public service facility layout method and system based on a service isochronous circle, and belongs to the field of urban planning, and the method comprises the following steps: actually measuring the walking uphill and downhill speeds under different slope topographic conditions of a mountain village and town, and building a slope-speed regression equation; calculating the actual uplink and downlink speed of each road section of the mountain village and town road network by using the regression equation; establishing an isochronal circle model for various village and town public service facilities, calculating the construction land coverage rate in an isochronal circle, and determining whether to newly build public service facility points according to the size of the proportion; and adjusting the distribution positions of the new public service facility points. According to the method, storage and calculation are carried out through a storage medium and a calculation execution device. Meanwhile, the system comprises a data acquisition module, a calculation processing module and an output display module. Therefore, the pertinence and the accuracy of mountain village and town public service facility layout evaluation can be improved, and rational support is provided for construction decision-making of village and town public service facilities.

Description

technical field [0001] The invention belongs to the field of urban planning, and in particular relates to a method and a system for laying out public service facilities in mountainous villages and towns based on service isochrones. Background technique [0002] In the context of the new era, establishing and improving the system of public service facilities in villages and towns is a necessary way to improve the overall living standards of the people. On the basis of evaluating the rationality of the layout of village and town public service facilities, further optimizing the layout is an important part of urban construction to accurately allocate village and town public service facilities. For the villagers who use facilities, the rationality of the layout of public service facilities in villages and towns is not only the quantity and quality of the facilities, but also whether they can reach the facilities conveniently and quickly, that is, the time cost becomes an importa...

Problems solved by technology

However, at this stage, most evaluations on the rationality of the layout of service facilities are still limited to indicators such as the scale of facilities per capita and the service radius of facilities. Obviously, it is difficult to fully reflect the rationality of the spatial distribution pattern of public service facilities in villages and towns. Especially in mountainous cities, the topography and landform are special. There are many steep cliffs, and space obstacles such as uphill and downhill need to be overcome, resulting in a non-proportional relationship between the plane distance to the service facility and the actual travel cost

Secondly, the current evaluation and optimization methods for the layout of public service facilities in villages and towns are mainly aimed at traditional plain areas, and their planning experience is not suitable for the guiding significance of the layout planning of public service facilities in mountainous villages and towns.
