摘要
以梅岭国家森林公园内的洪崖丹井景区为例,探究森林景区内蓝绿灰空间的声景特征及差异性。通过实地调查获取测量数据,利用IDW法绘制声景地图,通过R语言对样本空间的音频进行分析得出PSD值、NDSI值、ACI值。对等效声压级与声景指数进行Kruskal-Wallis非参数检验,验证相关性并分析造成其声景差异的影响因素。研究结果表明,洪崖丹井景区内等效声压级(Leq):蓝色空间>灰色空间>绿色空间;平均功率谱密度(PSD值):蓝色空间>绿色空间>灰色空间;标准声景差异性指数(NDSI值):绿色空间>灰色空间>蓝色空间;声音复杂度指数(ACI值):蓝色空间大于其他两类空间,灰色空间与绿色空间大致相同。洪崖丹井景区仅在NDSI值上蓝色空间与绿色空间具有显著差异性(P=0.029<0.05),3类空间的Leq、PSD、ACI分布均无显著差异性。森林景区内蓝色空间最为吸引游客,因而导致该空间内声压级最大,人工干扰程度最高;绿色空间与灰色空间在声景观特征上无明显差异,两者和谐共融。
Taking the Hongya Danjing Scenic Area in Meiling National Forest Park as an example,this study explores the soundscape features and variations in blue,green and gray spaces within forest scenic areas.Field surveys were conducted to collect measurement data,and IDW method was used to create soundscape maps.Audio samples were analyzed using the R language to derive PSD,NDSI,and ACI values.Kruskal-Wallis non-parametric tests were performed on equivalent sound pressure levels(Leq)and soundscape indices to verify correlations and analyze influencing factors.The results show that in the Hongya Danjing Scenic Area:Leq follows the order of blue space>gray space>green space;average PSD values rank as blue space>green space>gray space;NDSI values are highest in green space,followed by gray space and blue space;and ACI values are highest in blue space,with gray and green spaces being similar.Significant differences(P=0.029<0.05)were only found in NDSI between blue and green spaces,while Leq,PSD,and ACI showed no significant variations across the three spaces.Blue spaces in forest scenic areas attract the most tourists,resulting in the highest sound pressure levels and anthropogenic interference.Green and gray spaces exhibit no distinct differences in soundscape characteristics,coexisting harmoniously.
