| With the rapid development of social economy and constant improvement of people s living standard;urban residents have increasingly high requirements for life quality and demands for urban outdoor leisure and entertainment.Out of limited land conditions in hilly cities,in order to coordinate the contradiction between hilly cities’ demand for construction land and citizens’demand for leisure space in parks,to apply the hill green land embedded in the downtown and surroundings is an effective approach of solving this contradiction.Meanwhile,it also keeps in line with the idea of urban ecological civilization construction that urban construction in the new era takes the nature as beauty and integrates good hill and water into the urban.Hilly cities in Central Guizhou Region solve the realistic contradiction between the increasing demands for recreation and insufficient recreation places by strengthening the construction of Karst hill parks.It is mainly divided into two types:First of all,newly build Karst hill parks on the natural hill green land.Second,improve and transform Karst hill parks with longer completion time.However,compared with regular landform parks,tourist capacity is the prerequisite of applying hill green land as parks and the main restraint.Therefore,to study the characteristics of tourists’ recreational behaviors and tourist capacity of the Karst hill parks that have been constructed is of great important theoretical and realistic meaning to judging whether hill green land resources could be used as parks,thinking about how to improve the tourist capacity of Karst hill parks and guiding the planning design of Karst hill parks.Based on protection of Karst hill green land resources,this paper selects Karst hill parks in the downtown of Central Guizhou hilly cities(Guiyang Urban,Anshun Urban)as the research object,and carries out the following research results:(1)Basic conditions and characteristics of Karst hill parks.Based on high-resolution remote-sensing image,it classifies land conditions and space types of Karst hill parks through spatial information technology.The results indicate:80%of the space of Karst hill parks is the negative space,which is hard to enter or tourists hardly enter;20%is the positive space,which is the main recreational space for tourists to have fun in the park.(2)Analysis of temporal and spatial variation of number of tourists in Karst hill parks.By integrating video monitoring data and statistics of field investigation data,it analyzes the temporal and spatial variation tendency of number of tourists in Karst hill parks.Two periods from 07:00 to 09:00 and 14:00 to 16:00 are the entry peaks of Karst hill parks.When tourist intensity of positive space(recreation site with smaller slope)is>300 person-time/h/hm2,tourists gradually turn from the flat ground place to hill recreation space.The number of tourists that have a rest on hills in spring and summer is the biggest,followed by autumn and then winter.(3)Set up the calculating model of tourist capacity of Karst hill parks.Analyze the limiting factors of Karst hill parks and its importance.Formula for calculating maximum visitor capacity:KHPTCCmax=Rrccmax+Rgccmax+Ewcc+Rwcc+Ricc总(1)Formula for calculating minimum visitor capacity:KHPTCCmin = Rrccmin + Rgccmin + Ewcc + Rwcc + Ricc总(2)The most suitable formula for calculating the capacity of visitors:KHPTCC =Rrcc+Rgcc +Ewcc+Rwcc+Ricc总(3)By combining estimated calculation principle of tourist capacity and analysis of ecological sensitivity,it constructs the calculating model of tourist capacity of Karst hill parks,and factor spectrum of recreation activities in Karst hill parks.The future research orientation of tourist capacity of Karst hill parks:Seek for the balanced relationship between ecological environment of Karst hills and tourists’ activities from the perspective of ecological protection;improve the accuracy and scientificity of tourist capacity calculation of Karst hill parks;maximize the landscape benefit and social benefit of green land resources of Karst hills. |
