Research On Landscape Evaluation Based On Tourism Big Data

Big data has shown scientific advantages in landscape planning and design,but landscape evaluation is rarely supported by big data.Nowadays,Chinese tourism industry is booming.Tourists have left an amount of data on the Internet,providing a new perspective for landscape evaluation.Based on the strategic development of tourism in Lishui City,this article takes Lishui City's landscape as the research object,hoping to comprehensively and scientifically analyze the disadvantages and problems of Lishui's landscape planning,and explore new ideas of improving Lishui's landscape planning.With the background of the Internet era,having researched big data and landscape evaluation theory,the semantic difference method,factor analysis method,and GIS analysis method have been established to evaluate and analyze the landscape of Lishui City.This paper collected big data of evaluation of all attractions in Lishui City on Ctrip and Qunar websites and build a semantic evaluation analysis model based on big data.The six major landscapes in Lishui City were selected,and semantic difference method was used in combination with the literature to determine 28 pairs of adjective pairs as indicators for landscape evaluation in Lishui City.Supplemented by sentiment analysis in natural language processing to obtain a quantitative SD method landscape evaluation table,five characteristic factors were extracted by factor analysis method as follows: landscape image factor,impression-transfer factor,spatial organization factor,place perception factor,and environmental atmosphere factor.The six landscape samples were rated on the five characteristic factors.The relationship between landscape distribution and tourists distribution in Lishui was obtained by GIS analysis method.The results and conclusions were obtained through research as follows: First,this research designed a big data semantic analysis model process and confirmed that natural language processing can be used as a quantitative method for semantic difference method.Second,people-oriented,this research constructed a landscape evaluation analysis from the perspective of tourists.Based on the model,a landscape evaluation system suitable for Lishui city was obtained.Third,the advantages and disadvantages of the landscape in Lishui were analyzed and summarized.Fourth,in view of the landscape planning and construction of Lishui,this paper proposed some advice for the Lishui landscape improvement plan in the macro level landscape plan improvement,the meso level landscape design optimization,and the micro level landscape detail reconstruction.
