基于层次分析法的森林公园风声景评价研究

AHP Based Evaluation of Wind Soundscape in a Forest Park

以福州国家森林公园为例,应用层次分析法(Analytic Hierarchy Process),通过3个准则层因素和17个指标层因素探究影响森林公园风声景感受的景观指标。结果表明:在准则层的重要性排序中,植被群落结构因素>植物器官因素>建筑材质因素,所占权重分别为37.54%、35.88%和26.58%。在指标层的重要性排序中,隶属于准则层中植物器官因素的风吹树叶声的权重值远高于其他因子,占总权重的10.26%,进一步说明叶作为植物的主要器官之一,在风作用下产生的声景观感受的重要地位。有关结论为今后科学系统地开发、建设森林公园提供理论基础。

With the Fuzhou National Forest Park as an example,the Analytic Hierarchy Process(AHP)is used toevaluate some important factors which influence wind soundscape in forest parks,including three criterion layer factors andseventeen index layer factors.The results show that the order of the importance of the criterion layer is vegetationcommunity structure factor>plant organ factor>architectural material factor,the weights are37.54%,35.88%and26.58%respectively.In the order of the importance of index layer,the factor of sound of wind blowing the leaves,whichbelongs to vegetation community structure factors of the criterion layer,is greater than the other16factors,accounting for10.26%weight.It further illustrates that as the main organs of the plant,the leaves play an important role in evaluating thewind soundscape in forest parks.This paper provides a theoretical basis for the scientific and systematic development andconstruction of forest parks.
