城市舒适物、经济机会、城市规模对中国高学历劳动力空间分布的影响

基于中国2010年人口普查资料和社会经济统计等数据,采用空间分析方法探讨中国300个城市高学历劳动力的空间分布特征,并基于负二项回归模型识别其影响因素。研究表明：1）中国城市高学历劳动力规模呈现级差化分异特征,其位序-规模分布符合幂函数特征,在空间上呈现集聚分布和东中西地带性分异的格局;东部沿海地区、辽中南半岛、哈长城市群及内陆省会城市是主要分布地。2）从高学历劳动力占总就业的比例看,北方资源型城市及东部沿海城市群高学历劳动力优势突出,中部和西南地区存在明显“凹陷”;从高学历劳动力和总就业劳动力耦合的结果看,相对占优型和绝对占优型两类城市主要分布在内蒙古和东北的工业城市、京津冀、山东半岛、长三角、珠三角城市群及内地省会城市。3）实证结果表明,高学历劳动力的空间格局受城市舒适物、经济机会及城市规模带来的集聚效应共同影响。从全国层面看,经济机会、城市规模、房价主导高学历劳动力的空间格局,凉爽的夏季气候、优质中学教育资源、游憩及交通资源对其也有重要影响作用。4）在不同规模等级的城市中,高学历劳动力的空间分布均受到经济机会和舒适物的影响,但舒适物因子在各类型城市中发挥的作用差异较大。     

Functional Zoning Mode and Management Measures of Qianjiangyuan National Park based on Ecological Sensitivity Evaluation

Functional zoning is an important guarantee for regulating the land use intensity of national parks and maintaining the integrity and stability of natural ecosystem. In this paper, we tease out of the functional zoning models and methods based on the empirical analysis of the world national parks, and then take the Qianjiangyuan National Park (QNP) as an example, study the functional zoning method based on ecological sensitivity. Results show that, the goal of national park construction in the world is changing from enhancing national cohesion to displaying the national image, from the pure natural protection and recreation use to protection of the comprehensive function of natural ecosystem integrity protection, recreation, environmental education, etc. The establishment of QNP is to protect the natural ecosystem of sub-tropical lowland broad-leaved evergreen forest, also to meet the community development and recreational consume of large population in Eastern China. So this paper establishes an evaluation index system based on ecological sensitivity, combining ecosystem services, potential habitats of important species, and development opportunities. Based on the analysis result, the functional zoning of QNP can be divided into strict protection area, ecological conservation area, traditional using area and recreational area. In this way, it can make the functional partition reflect system controls thought in area difference and space layout, and take the corresponding management measures in different functional areas, to promote the sustainable evolution of the natural ecological system in national park.     

A population based assessment of the geographical accessibility of outdoor recreation opportunities in New Zealand

Active participation in the outdoors not only provides enjoyment and adventure, but it is also important for health and promoting conservation values. The latter is particularly important for young people as they are at an impressionable stage in their lives. Geographical accessibly of recreation opportunities can be a major barrier to utlization of the New Zealand outdoors. While it would be ideal to have a variety of opportunities available to everyone regardless of residence, the distribution of opportunities is constrained by the extent of suitable lands. This research provides a population based assessment of the geographical accessibility of recreational opportunities. Accessibility has many dimensions and includes cultural, financial, and geographical barriers; therefore this research is only addressing one dimension of accessibility. Geographical Information Systems is used for the analysis, which involves a function called least-cost path analysis. This identified the travel time (using a private vehicle) via the quickest route from where people live (represented by census enumeration points) to the entry point of the recreation sites. The outputs of this research are maps and spatial statistics on the travel times to a range of recreation opportunities for different parts of New Zealand. This information is important for recreation planning. In addition, the information also provides research opportunities for modelling recreation use, especially when accessibility information is combined with landscape experience information and recreation usage statistics.     

Modeling large-scale winter recreation terrain selection with implications for recreation management and wildlife

Winter recreation is a rapidly growing activity, and advances in technology make it possible for increasing numbers of people to access remote backcountry terrain. Increased winter recreation may lead to more frequent conflict between recreationists, as well as greater potential disturbance to wildlife. To better understand the environmental characteristics favored by winter recreationists, and thus predict areas of potential conflict or disturbance, we modeled terrain selection of motorized and non-motorized recreationists, including snowmobile, backcountry ski, and snowmobile-assisted hybrid ski. We used sports recorder Global Positioning System (GPS) devices carried by recreationists at two study areas in Colorado, USA, (Vail Pass and the San Juan Mountains), to record detailed tracks of each recreation type. For each recreation activity, we modeled selection of remotely-sensed environmental characteristics, including topography, vegetation, climate, and road access. We then created spatial maps depicting areas that recreation activities were predicted to select and combined these maps to show areas of potential ecological disturbance or interpersonal conflict between motorized and non-motorized activities. Model results indicate that motorized and non-motorized activities select different environmental characteristics, while still exhibiting some similarities, such as selection for ease of access, reflected in proximity to highways and densities of open forest roads. Areas predicted to have only motorized recreation were more likely to occur further from highways, with greater forest road densities, lower canopy cover, and smoother, less steep terrain, while areas with only non-motorized recreation were closer to highways, with lower forest road densities, more canopy cover and steeper terrain. Our work provides spatially detailed insights into terrain characteristics favored by recreationists, allowing managers to maintain winter recreation opportunities while reducing interpersonal conflict or ecological impacts to sensitive wildlife.     

Factors of spatial distribution of recreation areas in peri-urban Beijing

Based on the case study of peripheral urban areas in Beijing, this paper aims to identify the factors which will influence the spatial distribution of peri-urban recreation areas, by analyzing the collected data from questionnaires, online survey, documentation and field investigations (2007). In order to achieve sound information, relevant data from different management departments, owners and land-use types involved in the case study area are collected. A sampling database for peri-urban recreation areas in Beijing is established, and GIS spatial analyses as well as statistic analyses are applied. The result indicates that spatial distribution of recreation areas is majorly influenced by four factors, e.g. tourism attractions and environmental conditions, policy and spatial governance, consumption demand and preference, land price and availability. Tourism attractions and environmental conditions are dominant factors for public recreation areas. Commercial recreation areas are highly related with accessibility. Agricultural recreation areas are usually attached to special farmlands near large-scaled scenic areas. Meanwhile, recreational business clusters have appeared in suburbs influenced by mass recreation market growth. Controlled by the land price, commercial recreation areas are differentiated on their scales and developing intensity. Policy and spatial governance have made arrangements of recreation areas more balancing and more human-oriented. A peri-urban recreation area model is therefore established on the basis of this analysis, which can guide urban planning and designing, land-use planning and recreation resource development.

THE GEOGRAPHY OF HOUSING VALUES IN THE TRANSFORMATION TO A MARKET ECONOMY: A CASE STUDY OF MOSCOW

Rapid progress of the market-oriented reform in Russia has led to the emergence of urban housing markets. The intraurban spatial differentiation in market valuation of housing suggests a conceptually new insight into the internal structure of the socialist city. This paper demonstrates that apartment prices in Moscow are largely determined by accessibility to the center of the city, social status of the neighborhood residents, and proximity to certain amenities such as recreational facilities or disamenities such as noxious industries.     

Linked to Landscape: Assessing Urbanization in Germany through Landscape and Economic Factors

The ongoing encroachment of urban land into natural landscapes has resulted in the degradation of ecosystems throughout Europe. Understanding why the share of urban land has increased is important for managing urban growth and maintaining ecosystem services. We estimate a model of landscape change that integrates geospatial and socioeconomic data in a spatial autoregressive model to explain the variance in urban growth observed in Germany between 2000 and 2006. In doing so, we test several determinants of urbanization identified by theoretical frameworks from landscape ecology and economics, including landscape pattern and transit infrastructure. The results show that despite planning guidelines and policies to promote dense development, urban growth has been extensive. Regions with a high degree of fragmented land and the prevalence of environmental amenities are characterized by particularly strong growth, pointing to challenges in crafting landscape policies that balance economic development with environmental conservation.

Combining conventional and volunteered geographic information to identify and model forest recreational resources

It is now common for researchers in natural resource management and economics to develop spatial models of recreation demand for the purposes of valuation and planning. Such an approach has significant advantages but requires access to relatively detailed spatial data. In the absence of official data concerning resources, researchers may benefit from employing increasingly available volunteered geographic information (VGI) as a central source of data or to complement more traditional data sources. This paper describes the development of a map of forest recreational resources in Ireland by combining conventional forest cover data and VGI of recreational trails. As an extension the new map is combined with household survey data to explore respondent's ability to identify local recreational forests and models the impact of the characteristics of the closest forest on their annual visitation. The results suggest that VGI can be a useful resource to researchers in both the identification and characterisation of recreational resources. In addition, this paper finds that the distance to and characteristics of the nearest recreational forest has a significant impact on total annual visitation by members of the public.     

国家公园游憩利用与社区协调的空间重构机理与联动逻辑

游憩活动带来的“人”与“地”的互动使国家公园原本的人地关系有了更复杂的内涵。国家公园的社区协调与游憩利用需要联动发展,其机理是当代社会由流空间与地方场所形成的空间重构。以流空间理论为基础,解析国家公园空间重构机理,构建游憩利用与社区协调的空间联动逻辑模型,结果发现：1）国家公园生态空间所具有的独特资源禀赋是生活空间、生产空间、游憩空间运行发展的基础,生活、生产、游憩空间三者都影响生态空间的生态承载力。2）生活空间中原住民的地方依恋和文化认同都起源于生态空间,为游憩空间提供人文资源,通过宜居程度和生活保障的提升来促进生产空间的优化。3）生产空间也为游憩空间提供具有原真性的文化资源,通过生产方式的转变和就业渠道的增加提高原住民的收入水平,带动生活空间的改善。4）游憩空间所产生的经济资本和文化资本能够助力于生态空间的维护、助力于生活空间的改善和生产空间的优化。因此在未来的国家公园建设与发展中,一是需要根据流空间结构,推进游憩利用与社区协调的科学管理;二是基于空间重构机理,促进游憩利用与社区协调的要素流动;三是需要利用空间联动逻辑,完善游憩利用与社区协调的多元发展模式。     

基于RS和GIS的喀斯特山区景观生态格局

喀斯特地区生态脆弱性特征受各种自然和人为因素综合作用的影响。本文选取桂西南典型喀斯特山区，集成GIS和RS技术提取景观生态格局信息，运用景观生态学的基本理论和方法，在FRAGSTATS*ARC软件支持下，以分维数、形状指数、景观优势度、景观破碎度和相邻指数等景观格局指标，对该区脆弱生态环境的景观格局进行定量分析。结果表明石漠斑块已经占据景观的主导地位，景观格局呈现明显的破碎现象，必须采取综合措施进行生态重建。     

Assessing linkages between ecosystem services,land-use and well-being in an agroforestry landscape using public participation GIS

While a number of studies have applied public participation GIS (PPGIS) approaches to the spatial assessment of ecosystem services, few have considered the associations between the spatial distribution of ecosystem services and the context-specific nature of self-reported well-being. In this study, we engage the general public to identify and map a range of ecosystem services that originate in place-based, local knowledge and explore the context-dependent nature of subjective well-being. We conducted a PPGIS survey with 219 local residents in a Spanish agroforestry (dehesa) landscapes and analysed the spatial patterns of mapped ecosystem services, their relation to land cover, protected area and common land patterns. In addition, we explored the landscape values contributing to people’s well-being; and the relationships between ecosystem services in different land covers, landscape values and socio-demographic characteristics. A mosaic of landscape types (i.e., the landscape) provided more ecosystem services (especially cultural and provisioning) to people compared with the individual land system of agroforestry. However, land tenure and public access significantly guided the spatial practices and values of the people beyond the preferred landscape types. The contribution of the landscape to well-being is largely related to values based on interactions among people and the landscape, as tranquillity/relaxation and people-people interactions such as being with family and friends. We discuss the specific contribution of agroforestry landscapes to the provision of ecosystem services and human well-being. We conclude that the integration of the applied methods of social-cultural assessment on the one hand links to ecosystem services frameworks but on the other hand represents a more holistic conceptualisation of people’s benefits from landscapes.

绿带是阻止城市蔓延、提高城市生态安全格局的重要手段,其游憩开发能够为大都市游憩空间紧缺提供有效的解决途径。以北京市第二道绿带为研究区,以2013年绿带内6种类型游憩空间（共448处）为研究对象,运用Kernel核密度算法等空间分析方法,从北京市绿带游憩空间的整体分布格局、规模容量特征和各类型游憩空间分布特征及成因三个层面进行分析。主要结论：① 从整体分布格局来看,北京市绿带内形成了若干游憩空间集聚区域,游憩空间结构出现“北密南疏”的整体特征;北部游憩空间集聚程度高且分布连续成带,南部游憩空间集聚程度较低且分布离散成团;北部温榆河沿岸地区游憩空间大量集聚,成为绿带游憩空间结构的主要骨架。② 从规模容量特征来看,占地规模较大的游憩空间呈集聚分布,规模较小的游憩空间呈分散分布,绿带内已形成了6个由面积规模较大的游憩空间密集分布构成的热点区。③ 绿带内6种类型游憩空间分布特征及成因表现为：绿带内的资源环境本底决定了既有吸引物游憩空间的空间特征;政策性规划引导郊野休闲公园空间分布相对均匀;重要水系与运动健身游憩空间的空间分布高度关联;主题活动游憩空间更倾向于靠近主要交通干道;会议度假游憩空间与北京市地热资源分布契合度高;民俗体验游憩空间大量分布在海淀区上庄水库周边。揭示了北京市绿带游憩空间布局情况,为中国绿带游憩体系的统筹建设、空间结构调整和布局优化提供了参考。     

基于POI的城市休闲空间格局分析——以乌鲁木齐市为例

基于百度POI数据,运用Ripley’s K函数、最近邻层次聚类、空间自相关等方法,对乌鲁木齐市公共休闲设施空间布局进行研究,总结城市休闲空间的格局特征,进而探讨休闲空间的影响因素。结果表明：（1）乌鲁木齐休闲设施空间分布表现出明显的向心集聚性。（2）各类休闲设施热点区分布表现出不同的集聚倾向,娱乐类、购物类、健身类三类休闲设施热点区主要布局在主城区以内重要交通枢纽和商业中心附近,餐饮类休闲设施热点区表现出明显的人口导向特征,旅游类休闲设施热点区均分布在热门旅游景区附近,文化类休闲设施热点区分布于科教文化基地或多民族混居区。（3）乌鲁木齐市休闲空间格局为“圈层+扇形+组团”模式,核心为面状综合型休闲中心,外围为扇形的休闲设施稀少区、组团式多功能休闲区和组团式餐饮休闲区,最外围是休闲设施极少的郊区和组团式旅游休闲区。（4）乌鲁木齐休闲空间与人口空间分布存在较强的空间正相关关系。     

基于人口特征的城市生态游憩空间配置——以常熟市为例

生态游憩空间配置是休闲城市建设的重要内容,对城市生态文明建设、城市优质生活环境营造具有重要意义。本文以国家休闲城市综合标准试点市——常熟市为研究对象,以人口特征为切入点,对该市不同功能区内各年龄段人口数量、可进行生态游憩的时间、生态游憩意愿、对不同生态游憩空间的偏好,以及全市不同功能区人口对生态游憩空间的配置需求进行了调查研究。人口特征影响城市生态游憩空间的配置需求,全市不同功能区的人口特征有显著差异,因此对各类生态游憩空间的配置需求不同。在人口量、人口平均生态游憩可能性、人口生态游憩空间类型偏好等因素的影响下,商业活动区内人口对各类生态游憩空间的配置需求指数均最高,其次为生活居住区、商务办公区、工业生产区;全市不同功能区内人口对草地游憩空间的配置需求指数均最高,其次为水域和林地。可根据城市不同功能区人口数量、类型、分布特征,以及对各类生态游憩空间的配置需求来指导城市规划建设中生态游憩空间的配置实践。     

A GIS-based exploration of the relationships between human health,social deprivation and ecosystem services: The case of Wales,UK

Being able to analyse the relationships between people and nature has always been of key interest to ecosystems conservation, planning decisions and in a number of disciplines of natural and social sciences. In this framework, it is of paramount importance to evaluate possible correlations between factors such as ecosystem services, human health, and social deprivation. The present study aims at exploring relationships between ecosystem services, human health, and social deprivation for the region of Wales in the United Kingdom. Wales is of special interest because as a region it offers many ‘green’ ecosystems which have already been found to have a positive influence on humans' well-being as well as on socio-economic status. First, a recreational layer showing the size and location of all potential recreational areas in each Welsh local authority was created. Subsequently, correlation/regression analysis and weighted raster analysis were performed which allowed determining quantitatively the degree of correlation between the observed socio-economic factors and recreational areas.The findings of this exploratory study suggested that the relative size of potential recreational area varies widely within the local authorities comprising Wales. Not all the socio-economic factors which were examined herein found to be correlated with recreational areas. Some variables, such as income and employment deprivation showed high correlations with poor recreation options. Very poor correlation was also reported between recreation options and variables such as life expectancy and long-term illness. Our results, in agreement to previous studies conducted elsewhere, suggested that human health is determined by a complex interplay of more than one of the observed determinants, including for example biology and genetics or living and working conditions. As to our knowledge there are no prior research studies on the topic for our study region, this work provides a key contribution concerning the determination of a “social” value of ecosystems in the context of human health and other socio-economic factors. However, as these are only initial results, further work is required to verify those.     

景观空间异质性对地表水质服务的影响研究——以河南省伊河流域为例

人类干扰使景观空间异质性发生了剧烈变化,进而对生态系统服务产生了严重影响。目前,针对景观空间异质性与生态系统服务的关联关系研究还较为薄弱。以河南省伊河流域为研究区域,以地表水质服务为研究对象,分析了地表水质服务的空间变化;通过以水质采样点为中心建立缓冲区,分析了不同尺度下的景观空间异质性特征,并与地表水质指标进行相关性研究,以探讨景观空间异质性与地表水质服务间的影响规律及响应机制。结果表明：① 研究区地表水质状况整体上为西南、东北部较差,中部较好;② 从景观组成来看,林地面积占比或斑块个数的增加有利于地表水质的提高;③ 类型水平上,林地的景观构型与化学需氧量的质量浓度在200 m半径缓冲区内显著相关（P<0.05）,城镇用地的景观构型对地表水质的影响则在2000 m半径缓冲区内更为明显;④ 景观水平上,总磷的质量浓度受到景观构型变化的强烈影响（P<0.05）,景观构型异质性越低,总磷的质量浓度就越高;⑤ 适当增加景观空间异质性可有效降低地表水质污染物的质量浓度,提高地表水质服务。研究结论可为伊河流域的空间开发及水环境保护政策的制定提供科学依据。
