基于场论的动态缓冲区生成方法与应用

缓冲区可分为影响度只呈单一距离关系的静态缓冲区和影响度随距离变化而呈不同强度的扩散或衰减的动态缓冲区。本文通过对现有动态缓冲区算法在实际应用中存在的不足与局限的分析,提出了一种新的基于场论的动态缓冲区生成方法。该方法以场论的观点为指导,打破了传统缓冲区在进行重叠合并时简单地采用影响度小的服从影响度大的方法,而是按照场强叠加的原理,将各个影响度进行叠加来生成动态缓冲区。论文按照实际需要,提出了两种新的动态缓冲区模型,给出基于场强积分原理的动态缓冲区影响度的计算方法,实现了基于场论的动态缓冲区的生成,并成功应用于实践中。

A field theory based dynamic buffer analysis algorithm and its application

Buffer is a zone around a geographic entity to find what extent it influences the other objects around it.Static buffer is only a simple zone around the entity,but in dynamic buffer,the influence is changed along with the distances between the entity and the objects around.This paper proposes a new dynamic buffer analysis algorithm based on the theory of fields by analyzing the existing demerits and limits in application of it.The algorithm based on field theory breaks the traditional way on the overlap com...
