| The change of land use is a hot topic in the research of current scholars,and the research on driving force is also the key point of land use change research.The study of land use change and its driving force is of great significance to understand the current situation and the trend of land use.There are many factors of land use change,but lack of systematic research on tourism factors.In this paper,it takes Wuxi as the study area,the basic of land use change data,analyzes the situation of land use change of Wuxi from1992 to 2014.Then it uses SPSS20.0 correlation analysis and TOPSIS evaluation method to analy the driving factors affecting land use change in Wuxi.The results of the analysis is mainly divided into the following two aspects:(1)Land use change.First,land use quantity changes,arable land,woodland,grassland is decreasing continuously,residential area and industrial and mining land,other agricultural land,water conservancy facilities land area increase.Secondly,the change speed of land use is the most rapid,followed by the unutilized land.Next,land for other agricultural land and water conservancy facilities;As a whole,land use changes were relatively small during 1995-2000 and 2010-2014.The equilibrium degree of land use structure also fluctuates,but it is still growing in general,indicating that the land structure of Wuxi is becoming homogenized.In particular,the grassland changes the fastest,the unused land is faster,the land of agricultural land and water conservancy facilities is the slowest.Finally,in terms of the degree of land use change,the comprehensive index of land use in Wuxi was significantly reduced from 1992 to 1995,indicating that there existed problems in the land use process at that time,and the land structure was not reasonable.Thecomprehensive index of land use in 1995-2014 showed a slow growth trend,indicating that the land use structure of Wuxi was improved and the efficiency was obviously improved.(2)Research on tourism driving mechanism.First using SPSS20.0 to land use change in Wuxi city and tourism economy has made the overall correlation analysis,and established the regression equation,results showed that the tourism economy with all kinds of land use correlation coefficient is bigger,the close relationship between land use and tourist economy in Wuxi.Then,the TOPSIS comprehensive analysis method was applied to select the relevant indicators of tourism factors and classify them,so as to construct a tourism driving mechanism affecting land use change and conduct research.In this paper,the driving force intensity value of land use change and the driving force evaluation value of five sub-factors on land use change are analyzed quantitatively.It is concluded that the driving effect of tourism factors on land use change is increasing year by year,indicating that tourism factors play an increasingly important role in the process of land use change.The driving intensity of the five categories of tourism factors is also not.In order to avoid the rise,the factors of tourism hotel,travel factor,travel agency factor,tourist factor and travel economy factor are the factors of strong and weak.To sum up,in this article,through correlation analysis and TOPSIS evaluation method,the driving force of land use change in Wuxi city and its tourism analysis,enriches and develops the theoretical basis of the change of land use evaluation system and method.At the same time,in order to ensure the reasonable structure of land use and the good development of tourism in Wuxi city as a national excellent tourist city. |
