旅游生态足迹初探——以嵩山景区2005年"五一"黄金周为例

在生态足迹理论与方法的基础上,提出了旅游生态足迹的概念,运用旅游生态足迹计算模型,从旅游交通、旅游住宿、旅游餐饮和旅游购物等4个方面计算了2005年“五一”黄金周期间嵩山景区的旅游生态足迹,并与郑州市的生态足迹对比。结果表明:黄金周期间,嵩山景区游客的人均旅游生态足迹0.02264gha,是郑州市周人均生态足迹0.00436gha的5.19倍,旅游是一种对自然资源高需求、高消耗的生活方式。指出旅游生态足迹计算方法的特点,影响旅游生态足迹大小的关键因子,减少旅游生态足迹的途径和旅游生态足迹计算中存在的问题。     

Application of Landsat satellite imagery to monitor land‐cover changes at the Athabasca Oil Sands,Alberta, Canada

A major advantage of satellite remote sensing is that the imagery acquired provides a synoptic view of the landscape. Thus, repeat coverage by the satellite on a regular basis permits the detection of changes in land‐cover over time. This study demonstrates the application of remote sensing technology to the monitoring of mining activities at the Athabasca Oil Sands region of Alberta, Canada. First, we describe the techniques used to match a time sequence of Landsat imagery, both spatially and spectrally, to ensure that the spectral changes through time are due to land‐cover variations. A series of spectral trajectories were then extracted to assess changes in land‐cover through time. Secondly, a land‐cover classification was produced from the baseline 1984 imagery and, using historic and future mine extents, the classification was analyzed to determine the proportion of each land‐cover type affected through development. Results of the analysis indicate that since 1984 there has been a larger reduction in mixedwood dense and broadleaf vegetation classes than mixedwood sparse or dense conifer stands in the area. Based on the delineations of mine‐site activity, the area of woodland and wetland habitat subject to development has increased from approximately 2,520 hectare (ha) in 1984 to 32,930 ha in 2005.     

明清时期汉水下游地区的地理环境与堤防管理制度

明清时期国家对于汉水下游的水利管理制度经历一个变迁的过程,与这一区域的水利问题的日益突出密切相关,垸田的发展以及带来的问题是主要的因素。钟祥至沙洋的汉江干堤极易溃决,并且关系到整个下游地区的安全,因此在人力组织、资金筹集、岁修维护上,国家的政策表现出明显的倾斜性,相对于沙洋以下的区域,给予了充分的重视。沙洋以下,天门、潜江、沔阳等州县所在区域主要以垸田为主,国家将这一区域的堤防修筑与维护主要交由地方来进行。垸堤岁修维护采取堤甲制的组织形式,由垸民完成,一方面没有固定的资金,另一方面在正常年景之下,垸民可以获得基本的物质生存,因此垸堤的维护面临相当的困难。     

宁绍地区史前文化遗址地理环境特征及相关问题探索

本从宁绍地区各个遗址不同时期遗存的海拔数据对比入手,试图找出距今7000至4000年间遗址环境变迁的规律,并从化生态学角度去分析、解释、推断诸如河姆渡化“缺环”说、宁绍地区7000年前古化地理环境、宁绍地区史前化遗址环境与聚落形态特征的关系等问题。     

Determinants of temporary labour migration in southern India

We present new data from three village panchayats in northwest Tamil Nadu and investigate the associations between demographic and socioeconomic factors with temporary labour migration from this setting. Individual (n?=?1110) and household (n?=?278) level logistic regression models were used to demonstrate how factors at each of these levels can influence temporary labour migration trajectories. Young males were most likely to temporarily migrate for work from this region. Additionally, large households from historically disadvantaged castes with marginal land and housing were most likely to have at least one migrant member. Households with multiple migrant members appear to use temporary migration to cope with serious deprivation relative to households with only one migrant member. These findings provide a strong case that can be compared to other settings in India and can be used to inform improved policy and targeted development initiatives to support temporary migrant workers and their households.     

九十年代中东地缘政治的因素与机制探讨

中东是个独特的政治地理区域,90年代以来正在走向多极化。影响中东地缘政治的因素丰富多样,本文对其中的地理位置、国土、自然资源、民族、宗教、地区霸权等最重要的因素进行了简要的论述。并在提出国家影响力、地缘政治影响力概念的基础上,设计了简明的公式,对中东地缘政治稳定度作了定量探讨,文间还结合当前中东政局中的重大问题和主要特征进行了分析。     

《诗经》中农业地理知识探微

本文用地理学的方法,细致分析和探究了《诗经》中蕴藏的农业地理知识,其中包括农业自然资源条件、自然灾害、土地利用、重农思想、物候与农事活动。主要的粮食作物与经济作物、发达的畜牧业等。古为今用,作者通过对《诗经》中农业地理知识的深刻挖掘,得出了三个有益的启示。可为今日农业生产和农业地理研究提供一些借鉴。     

神话与宗教中理想景观的文化地理透视

神话与宗教是原始的哲学和宇宙观,理想景观是其中一个重要组成部分。根据文化圈的不同,世界神话与宗教可划分为三种地域类型:中国式、希腊式和希伯莱式。它们各有其不同的理想景观类型。理想景观是人们对于环境的选择和改造,它的形成受自然环境和文化的双重作用,其中自然环境的作用是潜在的、基础性的,而文化的作用是直接的和本质性的。不同的文化通过神话和宗教中的理想景观类型来表达自己的景观理想,又依据这些理想,通过地理回归在现实中使其物化,实现对地理环境的影响。     

主题公园拥挤感知的影响因素研究:以方特欢乐世界为例

近年来随着"黄金周"假期政策的出台以及消费者旅游需求的急剧增长,拥挤成为困扰国内众多景区发展的主要瓶颈之一,而目前关于旅游景区游客拥挤感知的研究却相对薄弱。文章以方特欢乐世界主题公园为例,运用IPA评价分析模型对影响主题公园游客拥挤感知的关键性因素进行了评价和讨论。结果表明,不同的学历与游客的拥挤感知差异性显著,呈负相关,男性的拥挤感知大于女性;时间和密度因素是影响游客拥挤感知的主要因素。最后从游客对园内的拥挤期望出发,提出了改进我国主题公园的管理和提高游客满意度的建议。
