流动商贩的分布特征及营业空间界面影响分析——以广州中山大道西路段为例 总被引:1,自引:0,他引:1
流动商贩的空间分布有较大的临时性和变化性,但在各种不同因素的影响下,也具有一定的特征性。研究其分布特征和影响因素对从空间上引导该非正规经济的发展具有积极意义,而已有从空间角度出发的非正规经济研究成果较少。本文主要采用实证研究的方法,选取广州中山大道西路段的流动商贩为典型案例,从空间的角度对流动商贩这种非正规经济来进行研究。研究发现,流动商贩的空间分布具有时间、空间和类型构成三个特征。影响其分布特征的空间界面因素包括界面用地性质、权属以及界面空间特征等,揭示流动摊贩空间集聚的根源,为城市的规划管理和建设提供一定参考。 相似文献

国内旅游现象空间分异研究进展与展望 总被引:2,自引:0,他引:2
在综述国内关于旅游现象的空间分异研究进展的基础上,作者认为,国内旅游地理学关于旅游现象空间分异方面的研究主要是从旅游资源、旅游产业和旅游地、旅游客源市场和旅游流、旅游地本身等旅游产业发展投入要素方面入手的,对于旅游发展的区域效果方面的研究显得有些不足。在与国外该领域研究进展进行对比的基础上,结合国际国内旅游发展和研究的趋势,作者提倡国内旅游地理学应加强旅游影响空间分异研究。阐述了旅游影响空间分异研究的意义以及基本内容,希望藉此促进我国旅游地理学乃至旅游学研究的进一步完善。 相似文献

Vegetation history at the multi-period prehistoric complex at Ballynahatty,Co. Down,Northern Ireland

Palaeoecological methods can provide an environmental context for archaeological sites, enabling the nature of past human activity to be explored from an indirect but alternative perspective. Through a palynological study of a small fen peatland located within the catchment of a multi-period prehistoric complex at Ballynahatty, Co. Down, Northern Ireland, we reconstruct the vegetation history of the area during the early prehistoric period. The pollen record reveals tentative evidence for Mesolithic activity in the area at 6410–6220 cal BC, with woodland disturbance identified during the Mesolithic–Neolithic transitional period ca. 4430–3890 cal BC. A more significant impact on the landscape is observed in the Early Neolithic from 3950 to 3700 cal BC, with an opening up of the forest and the establishment of a mixed agricultural economy. This activity precedes and continues to be evident through the Mid-Neolithic during which megalithic tombs and related burial sites were constructed at Ballynahatty. Due to chronological uncertainties and a possible hiatus in peat accumulation in the fen, the contemporary environment of the Ballynahatty timber circle complex (constructed and used ca. 3080–2490 cal BC) and henge (dating to the third millennium cal BC) cannot certainly be established. Nevertheless, the pollen record suggests that the landscape remained open through to the Bronze Age, implying a long continuity of human activity in the area. These findings support the idea that the Ballynahatty prehistoric complex was the product of a gradual and repeated restructuring of the ritual and ceremonial landscape whose significance continued to be recognised throughout the early prehistoric period. 相似文献

旅游目的地危机事件的影响评估新考量 总被引:6,自引:2,他引:4
目的地旅游业受到危机事件冲击后,准确地对旅游业受危机事件影响的时长及旅游损失进行评估,有助于把握危机影响规律,为危机管理手段的选取和旅游业恢复政策的制定提供科学依据。本文以2003年SARS事件为例,运用旅游本底趋势线法(TBTL),对我国入境旅游人次受其影响的时间长度和旅游损失进行了评估。研究结论是,SARS对我国入境旅游影响时间长达19个月,入境旅游人次损失为1368.91万人次。研究结论和实际一致。 相似文献

A survey of the visual effects of wind farms was undertaken in South Australia, with the aim of quantifying the impact of wind farms on the perceived scenic quality of landscapes. In the study a total of 311 participants assessed the scenic quality of a photographed landscape in 68 coastal and inland locations where wind farms could be located, both without wind farms and with wind farms digitally added to the scene. A key finding of the study was that wind farms generally had a negative effect on landscapes of higher scenic quality but a positive effect on landscapes of lower scenic quality. The negative visual effects of a wind farm did not reduce appreciably with distance. White, blue or grey coloured turbines were preferred over tan or rainbow hues, but this finding was based on a small number of scenes. Limitations of the study included using static views of wind farms and having an insufficient number of scenes to assess the influence of the number of turbines on scenic quality ratings. The study concluded that wind farms should avoid areas of higher perceived scenic quality, particularly on the coast, and be located in areas of lower scenic quality. The study adds to the growing body of international research on community attitudes to wind farms, and contributes useful knowledge for future planning of wind farms in Australia. These research results should assist communities, government agencies and the wind energy industry and improve the planning and design of wind farms by taking community perceptions into account. 相似文献

National laws, local traditions and practices largely define which spatial planning policies are pursued and how they are carried out. Still, like many other policy areas, an unmistakeable process of Europeanization is underway in planning. On the one hand, informal bottom-up Europeanization is occurring through the increasing interaction between scholars and practitioners and by the growing body of spatial information and analyses available at the European Union (EU) level. On the other hand, formal top-down Europeanization occurs when EU policies – competition, economic development, agriculture, nature protection, air quality, etc. – impact domestic spatial planning systems, policy and practice. In this study, we investigate this second kind of Europeanization, using the case of the Netherlands as an example. Specifically, we construct a map revealing the location of EU sectoral policy using six distinct impact types. We observed that many policies overlap and various inter-sectoral tensions (horizontal coordination) are present. The empirical analysis moreover revealed, in line with recent theoretical literature on multilevel governance, that domestic policies and practices, particularly at the national level, determine the way European policies affect planning. This finding has implications for all member states, but particularly those whose national planning is undergoing fundamental reform. 相似文献
