Study On Heterogeneity Of The Activity Space Of The Host And Guest Groups In Tourist Cities

Tourist cities group activities between Host and guest groups space can reflect tourist city spatial structure,transport infrastructure is configured and tourism development situation,understanding and explore tourist cities group activity space characteristics between host and guest groups,reveal the bus allocation of resources to host groups influence mechanism and law of activity space,to optimize the tourism city space structure,the rational allocation of transport resources is of great significance.Based on this,this article to tourist cities group activities between the perspective of spatial heterogeneity,this paper in order to "host community activity space features,analysis of characteristics of activity space,influence mechanism modeling,optimization countermeasures" logical train of thought of research,obtained the host community activity space characteristic and lijiang lijiang bus allocation of resources to host the influence factors of group activity space.The findings:(1)there are obvious differences in the spatial distribution pattern of the activity infrastructure of the host and guest groups in lijiang.(1)in the past five years,the number of main and guest group activity infrastructure in lijiang city has increased by a multiple,and the spatial distribution has shown the characteristic of "dense inside and sparse outside",decreasing from the center to the surrounding level.(2)the host groups activity infrastructure presents the trend of "blooming everywhere",while the guest groups activity infrastructure presents the trend of axis development.(3)upper lijiang city infrastructure in the space formed "one master once" two agglomeration centers,but different types of facilities space aggregation degree is different,the host groups in the space to form a single agglomeration center,and the guest groups in the space to form a number of agglomeration centers,showing the characteristics of contiguous distribution.(4)the infrastructure in the central urban area of lijiang city mainly centers around the two major government agencies of lijiang city government and ancient urban district government to form the "8" double-core hot spots;The hot spots of the main infrastructure activities are mainly concentrated in the center of the ancient urban area,and the cold spots are mainly distributed in the marginal areas.The infrastructure hot spots of the object activities are highly concentrated and have obvious stepped features,which are significantly different from the spatial distribution of the infrastructure hot spots of the host and guest activities.(2)there are obvious differences in the activity channels of host and guest groups in lijiang.(1)the bus hot spot in lijiang city presents the spatial characteristics of "circle structure".The core hot spot area and the core cold spot area of the bus stop in lijiang city are divided by the northeast to southwest axis,which is the core hot spot area at the top of the axis and the core cold spot area at the bottom of the axis.(2)there is an obvious dislocation and separation phenomenon in the space of the activity demand of the host and the guest group.(3)the main activities of the node and the direction of obvious characteristics,the ancient city center agglomeration and radiation capacity is the strongest;The spatial connection intensity of the object activity is characterized by a high axial strip,which is an axial-radial structure with the ancient city as the core.Commuter activity channels show the "inverted arrow" distribution characteristics,the general school activity channels show the axis distribution characteristics;The spatial connection intensity of the guest activity is characterized by a high axial strip,which is an axial-radial structure with the ancient city as the core.(3)the spatial pattern of the activity intensity of the host and guest groups in lijiang is different to some extent.(1)the activity intensity level of the subject as a whole shows the spatial distribution pattern of the word "ten",and the activity spatial intensity of the guest shows the axis distribution of the word "1".(2)the revolving radius of the host activities in lijiang city along the bus network presents a spatial pattern of "big outside and small inside";The travel distance of the main body is distributed in a circle of "short inside and outside".The diversity index of host activity is characterized by the spatial distribution of the word "大".(3)The rotation radius of the guest of lijiang city presents the distribution pattern of north-south axis;The travel distance of the guest shows an "L" type spatial distribution.The average diversity index of guest activities was 0.235.(4)the travel space distance of the guest in lijiang city is about 2 times of the travel space distance of the host.(4)the allocation level of public transport resources in the central urban area of lijiang city is weak in coupling and coordination with the activity space intensity of the host and guest groups groups.The coupling coordination degree between the allocation of public transport resources and the host activity space decreases to the periphery in the form of "十",while the coupling coordination degree between the allocation of public transport resources and the host activity space decreases to the periphery in the form of "1".(5)the spatial autocorrelation model of activity space intensity of the host and guest groups in lijiang is different.The spatial intensity of host activities in lijiang city has obvious spatial agglomeration on the whole,and the gradient from high to low is formed from the center to the periphery.The spatial pattern of guest activity in lijiang is more random.(6)the factors influencing the activity space intensity of the host and guest groups are different in the allocation of public transport resources.Bus network,bus network density and bus station coverage of 500 meters have a significant impact on the activity space intensity of the main body.In addition,the former shareholders of the main body activity space are impacted by the spatial spillover effect of the activity space intensity of the main body in adjacent regions.The number of public lines,the coverage of public stations of 500 meters and the accessibility of public bus stations have significant influence on the activity space intensity of the guest.
