旅游资源密度的概念及其应用——以从化市旅游资源为例

Concept and application of tourism resource density: a case of tourism resource of Conghua City

传统的旅游资源分布图难以实现对大量数据的全面反映和深度挖掘。借鉴物理学中能量辐射的原理,指出旅游资源单体也将其影响力以能量的形式向周围辐射,并将旅游资源的密度看作是旅游资源辐射能大小的分布。由此提出旅游资源密度的概念。根据旅游资源的特殊性,改进人口密度的核心估计模型,提出旅游资源辐射能的计算模型。运用GIS技术,以从化市旅游资源为例,制作生成旅游资源密度图。据此,从旅游资源分布的空间结构形式和旅游资源分区两个角度分析了旅游资源密度图在从化的应用。

Though tourism resource distribution map has quite a lot of merit and be an indispensable part in tourism resources survey report,it cannot reflect all the important survey result in a single map,which will prevent us to see the panorama of tourism resource distribution.What is more,tourism resource distribution map is a simple reflection of tourism resource,cannot reveal the inner relationship of survey information.In order to have a better view of tourism resource distribution,this paper uses the principle of energy radiation in physics for reference to put forward the idea of tourism resource density.It supposes that,tourism resource monomers radiate their influence in the same way as heat sources radiating their energy.The higher quality the tourism resource monomers have,the farther and stronger they radiate their energy.Every area is receiving the energy from the tourism resource monomers aside.So tourism resource density can be looked as the distributions of tourism resource radiant energies.The method of kernel density estimation is a good way to simulate this kind of condition and be widely used to estimate population resources density.As tourism resource density is not only care about the quantity of tourism resource monomers but also their quality,this paper take the kernel density estimation modal of population resources density for reference and consider the actual conditions to creates a new calculation model to measure the tourism resource radiant energies.Based on the survey date of Conghua we create a tourism resource density map with the help of GIS(geography information system) technology.It benefits a lot to analysis the distribution of tourism resources.According to the density map the tourism resource space structures of Conghua can be conclude clearly into four types: splattering structure,disperse-connected structure,single monomer structure,and polar aggregation structure.Different tourism resource space structures should have different development strategies.Based on the interrelations of the tourism resource monomer,considering administrative district and other factors,this paper segment Conghua into 14 basic sightseeing district and 3 tourism areas.
