城市居民对乡村旅游影响的感知研究——以上海、南京为例

乡村旅游的发展必然会对乡村经济、社会文化和环境产生影响.以2006年9-11月在上海、南京两城市所作的700份问卷调查资料为基础,利用SPSS和Excel软件,定量分析了城市居民对乡村旅游影响的感知.结果表明:城市居民对乡村旅游影响正面感知强于负面感知;可分为中立者(37.3%)、理性支持者(37.8%)和矛盾支持者(24.9%)3类,支持者多于中立者;人口学特征不同,其感知存在一定差异.

基于PPGIS的乡村旅游社区景观价值变化研究——以丽江束河古镇为例

景观价值是人对环境的主观感知和效用评价,景观价值变化的研究能够帮助理解旅游社区的社会现象.以丽江束河古镇为例,采用参与式制图与半结构化访谈方法调查当地居民对旅游开发前后的感知景观价值,最终获取的有效问卷与填图为293份,提取空间数据点658个.通过对访谈结果进行编码和归纳得到旅游开发前后各7种景观价值类型.采用质性分析...     

云南省乡镇农村地震灾害直接经济损失研究

根据1993-2003年30余次云南省地震的损失评估调查资料,建立了云南省农村乡镇各烈度区房屋建筑物损失与受灾人口的定量关系,初步建立了各烈度区水利设施损失、生命线工程损失与房屋建筑物损失的关系。以云南地区2004年-2005年4次地震为实例,用以上计算方法估算了4次地震的直接经济损失,并与地震现场评估的结果作比较,结果表明,该计算模型实用性强,对一般性地震的模拟误差平均值在30％左右。

Spatial Accessibility to Health Care Facilities in Suhum District,Ghana

To improve geographical accessibility to health facilities in rural Ghana, it has been recommended that additional health facilities be built. Resource constraints make this recommendation infeasible. Using location-allocation models, this paper demonstrates that in the Suhum District of Ghana substantial improvements in accessibility can be achieved with better locational choices and without additional facilities. Also, additional facilities will produce little improvement in accessibility if location is not explicitly considered. The paper demonstrates the utility of location-allocation models for improving accessibility to services in the Third World.     

Effect of relative humidity on the angular distribution of scattered light intensity for rural and urban aerosols

The change in atmospheric relative humidity affects the physical and optical properties of aerosol particles. It would be interesting to study the effect of an increase in relative humidity on the angular scattering of light by aerosols (by incorporating the changes due to it as the complex refractive index and the parameters of the size distribution function). In the present paper we have computed the angular scattering function for rural and urban aerosols, for light of wavelength 0.55 μn. The results obtained for these two models, representative of different environments, are interesting and show some discriminating features.

Space,Place, Population and Census Analysis in Australia

The Australian Census of Population and Housing is a census of people not places. However, where people live and work can be of major relevance in our search for explaining and understanding their behaviour. This paper argues that the place dimension in the Australian census has not been exploited very effectively in this respect. Three dimensions of the issue are addressed. Firstly, the spatial units commonly used for analysis of census data often are not appropriate to the problem being investigated. The spatial units in the Australian Standard Geographical Classification (ASGC) used for census data rarely represent meaningful social, economic and environmental regions. Secondly, the use of a simple urban/rural dichotomy is criticised as being a very blunt instrument to differentiate settlement types. Thirdly, the relationship between people and place in the census is discussed. While for the most part the census relates people to a single location—their place of usual residence—this is only one of the places with which people regularly interact. It is suggested that there is a need to adopt practices in the census which allow a range of population geographies to be defined. In conclusion it is argued that innovation in the Australian census, especially with the introduction of meshblocks and contemporary methodology and technology in Geographical Information Systems, makes it possible to analyse spatially referenced data in ways that can address these three issues.
