Abstract: 【Objective】 Using remote sensing data to discuss the planning and design method of soundscape in scenic area,we constructed a comprehensive evaluation model of comfort degree of soundscape, which provides a scientific basis for the development of tourism resources at the landscape scale. 【Method】 Taking the core area of Dr. Sun Yat-sen's Mausoleum Scenic Area in Nanjing as the research object, the comfort evaluation model of soundscape in scenic area is constructed by surveying the objective factors affecting the soundscape and referring to the results of tourists' subjective evaluation on the soundscape in the scenic area, and analysis and evaluation are implemented by using GIS software. 【Result】 The results show that the average sound level of the core area of Dr. Sun Yat-sen's Mausoleum Scenic Area in Nanjing is 66.88 dB. In the time dimension, the comfort degree of soundscape increases steadily at first and then fluctuates downward on average in every 24 hours. In the spatial dimension, the comfort degree of soundscape shows a patchy distribution trend where it is high in the south, medium in the middle and low in the east. The zones with higher comfort degree of soundscape are mainly located in the southeastern part of the scenic area, while those with low comfort degree of soundscape are mainly located in the southwestern fringe of the scenic area. In addition, the evaluation results of comfort degree of soundscape are positively correlated with landscape area, water area ratio and green coverage, negatively cor related to the linear distance between the scenic spot and the motorway, and have no obvious correlations to landscape diversity and road density. The threshold of comfort degree of soundscape is 64.62 dB. 【Conclusion】 The method of soundscape evaluation incorporating subjective and objective evaluation and spatial analysis method can provide reference for future comprehensive landscape planning and soundscape design of scenic spots in China.
