国内已从宏观尺度研究全国A级旅游景区的空间分布情况,但有关区域性旅游景区空间分布的研究较少。山东半岛蓝色经济区作为中国第一个蓝色经济战略区,具有很强的代表性。选取山东半岛蓝色经济区的284处A级旅游景区作为研究样本,利用蓝色经济区不同等级景区在各市区分布折线图得到不同等级景区的空间分布差异。利用空间分析和数理统计的方法,包括地理集中指数和基尼系数对其进行分析,辅以洛伦茨曲线对结论进一步验证,最终得到蓝色经济区的A级旅游景区在空间上呈现出集群分布、不均匀分布特点。采用聚类分析确定了旅游节点和旅游轴线,确立了以青岛为核心,向周围城市辐射发展的空间格局。 相似文献

长江中游城市群高等级旅游景区时空格局演变研究 总被引:1,自引:0,他引:1
《资源开发与市场》2020,(9)
应用地理学方法分析了长江中游城市群高等级旅游景区的空间格局演变及其影响因素。结果发现:①景区空间分布为凝聚型,其集聚强度在不同尺度上表现出先增加后减少的规律,一阶热点区位于省会城市和旅游资源丰富的城市。②景区空间分布不均衡,环鄱阳湖城市群形成以南昌、上饶为核心,九江、景德镇为次核心"U"型带状景区空间格局,其他3个子城市群则分别形成以宜昌、武汉、长沙为中心的环状空间格局。③长江中游城市群高等级旅游景区的空间格局主要受到经济和人口驱动,4个子城市群的影响因素呈现空间差异性。 相似文献

情感形象是旅游目的地重要形象之一。以外地游客的上海游记为语料,采用扎根理论研究法、内容分析法分析外地游客对上海旅游目的地的情感态度。结果表明:(1)游客对上海旅游目的地的情感态度总体上积极正面,体现在旅游吸引物、休闲娱乐、设施服务、环境氛围和管理服务5个维度上;(2)游客对上海旅游目的地的积极评价多集中在“繁华、现代、时尚、独特”高频词上,说明世界著名旅游城市形象已基本建成;(3)但是景区商业化、高物价和人多排队等因素带给部分游客负面情绪。针对此,本文提出了夯实景区文化内涵、加快全域旅游建设、加大宣传力度、加大精细化服务管理等提升城市旅游形象的建议。 相似文献

空气质量是影响旅游目的地发展的重要因素,游客目的地选择、旅游体验和重游意愿等与其关系紧密。获取2013年1月至2019年7月游客在携程网发布的259个国内5A级景区空气质量的13,069条评论,通过双向LSTM模型进行情感分析,借助Gephi、Vosviewer分析其共现网络图,并依托扎根理论诊断影响游客对景区空气质量感知的因素。结果发现:①游客对我国旅游目的地空气质量感知情感值正面极性显著,时间上呈稳中有升的趋势,空间上"南高北低"格局明显。②高情感值景区与景区类型相关,低情感值景区则受地理位置影响。③共现网络图谱和扎根理论分析均得出自然环境、身体健康和服务设施是影响情感值的主要因素。 相似文献

研究旅游资源的空间结构特征并开展量化评价是旅游资源开发与保护的重要前提。海螺沟景区是我国西部的典型景区之一,探讨其旅游资源的空间结构特征,并为景区旅游的开发提供理论依据,对我国西部山区旅游业的发展具有重要的示范意义。对海螺沟景区旅游资源的空间结构参数(连接度、通达度与紧密度)计算结果表明,海螺沟景区旅游资源的连接度β指数为1.0、平均回路数为9、γ指数为0.4,整体连接度较差;旅游资源的平均通达度指数为46.9,节点平均径路长为3.8,通达度较差;旅游资源的紧密度为0.72,整体为中等。针对研究结果,提出了海螺沟景区旅游资源的空间结构优化对策,可为海螺沟景区乃至我国西部其他山区旅游资源的开发与利用提供科学依据。 相似文献

通过对景点评论的内容分析,对比了男女性外地游客对上海南京路步行街的旅游意象。结果表明,男、女游客对这条步行街的整体印象无显著差异,对各种属性的感知相似性多于差异性,性别对城市步行街的旅游意象影响较小。基于游客对南京路步行街的意象,针对城市步行街类景区的规划与管理提出了建议。 相似文献

Trametes versicolor decolorized 2000 mg L(-1) of the mono-azo substituted naphthalenic dye Amaranth with no dye sorption observed visually. The changes in the toxicity were assessed over a period of 30 d for the dye-treated viable culture, control (no dye added), and a boiled culture treated with dye, using the Microtox Acute Toxicity assay. Before dye addition, the culture filtrate had some toxicity, which increased after the dye addition. The toxicity of the dye-treated culture decreased during the treatment. The loss of toxicity occurred at the same time, with the loss of color suggesting that detoxification is associated with decoloration. The change in pH was due to natural metabolic processes and had a small effect on detoxification. Because the toxicity of the treatment was similar to that of the control at the end of the treatment, the effluent seems to be safe for release into the environment, potentially rendering this treatment suitable for industrial application. 相似文献

The increase in the number of tourists visiting a coast is desired by most of the countries for economic reasons. However, this increase in tourism may cause pollution of the sea. This can be only avoided by proper planning and by predicting the carrying capacity of the coast in terms of sea pollution. This is especially important for developing countries where part of the wastewater is discharged without any treatment into the sea.In the present study the beaches were classified according to their use — and consequently the amount of waste discharged into the sea — into four groups: (1) coasts that are used only for swimming and recreational purposes; (2) coasts used simultaneously for dwelling, swimming, and recreational purposes; (3) coasts along which only dwellings exist; and (4) natural and man-made harbors, i.e., coasts used as shelters. During the survey,40,320 observations were made between December 1985 and February 1988 to determine the effect of the number of tourists on seawater quality. The results obtained were analyzed by a multilinear regression program to obtain an empirical equation giving the extent of the sea pollution in terms of coliform concentration as a function of population density and some other environmental factors.The equations derived in this study enable the determination of the carrying capacity of a beach in terms of pollution as well as the expected degree of pollution corresponding to a given population density. Furthermore, it allows the prediction of the extra carrying capacity that can be obtained by improving the waste-disposal conditions. 相似文献
