中文摘要: |
自然旅游资源的空间分布受到地质构造、地层岩性和地形地貌等多重因素影响,为了准确分析巴塘县自然旅游资源的空间分布及其影响因素。本文选取巴塘县575个自然旅游资源点,综合运用多尺度地理加权回归模型、核密度分析法和标准差椭圆对巴塘县自然旅游资源的空间分布和影响因素进行定量分析。结果表明:(1)区内自然旅游资源空间分布差异明显,在中西部和北东地区整体出现两个高密度“核心”区;(2)基于MGWR模型对地形地貌因素、河流水系进行分析,通过各影响因子回归系数,可知影响因子对自然旅游资源分布的影响程度在不同区域具有差异;(3)由于各地层岩性分布的差异,导致风化能力不同,形成不同的成景条件;(4)自然旅游资源分布点与构造延展方向一致,具有沿断裂构造聚集分布的特征。 |

The spatial distribution of natural tourism resources is affected by multiple factors such as nature,geological structure and stratigraphic lithologyIn order to accurately analyze the spatial distribution of natural tourism resources and its influencing factors in Batang CountyIn this paper,575 natural tourism resources in Batang county are selected,and multi-scale geographical weighted regression model,kernel density analysis,standard deviation ellipse and other spatial analysis methods are comprehensively used to conduct quantitative analysis on the spatial distribution and influencing factors of tourism resources in Batang CountyThe results show that:(1)there are obvious differences in the spatial distribution of natural tourism resources in the region,and there are two high-density “core” areas;(2)Based on the MGWR model,the topographic and geomorphic factors and river system were analyzedThrough the regression coefficients of each impact factor,it can be seen that the impact degree of the impact factors on the distribution of natural tourism resources is obviously different in different regions;(3)Due to the difference of lithology distribution in different strata,the weathering ability is different,resulting in different scene-forming conditions;(4)The distribution point of natural tourism resources is consistent with the direction of structural extension,and has the characteristics of aggregation and distribution along the fault structure |
