摘　　要：针对现有缓冲区分析常重影响范围轻影响力值、重静态缓冲轻动态缓冲、重缓冲半径轻约束条件,缺乏顾及多方要素的缓冲区分析综合模型的问题,该文基于分析对象、距离属性及约束条件3个基本要素构建了缓冲区分析综合模型,设计了缓冲区分析综合模型的实现方法,并从河面宽度、哨岗监控以及噪音扩散不同应用视角验证了综合模型的可行性。实验结果表明,缓冲区分析综合模型可有效综合多种缓冲要素的复合作用,适用于多样化的缓冲区分析应用需求。In view of most exsiting buffer analysis payed attention to the range of influence and overlooked the influence alue,emphasized static buffer and neglected dynamic buffer,while attached importance to buffering radius and made light of constraint condition,this paper built a buffer analysis model based on the analysis object,distance property and constraint conditions,then a realization method of the integrated model of buffer analysis was designed,to test the feasibility of the model,this paper involved three experiment,there were river width,sentries monitoring and noise spread.Experimental results showed that,the comprehensive model of buffer analysis could effectively synthesize the composite function of various buffer elements,which could be applied to the diversified buffer analysis and application requirements.
