论地球系统科学与可持续发展战略科学基础（Ⅰ）

地球系统科学是可持续发展战略的科学。它脱胎于气候系统研究，跨越一系一自然与社会科学，将全球变化与区域变化冶为一炉，所涵差的时间数十年至一二百年，在此时间尺度内，所涵盖的对象基本上是大气、海洋与陆地以及介于其间的物质能量交换过程。陆地最重要、最复杂、受人类活动的影响亦最大，目前未知数亦最多。宜先在跨学科的综合工作上多下功夫，积极推动地系统研究。

The place of rural, remote and least-wealthy small islands in international water development: the nexus of geography–technology sustainability in Chuuk State, Federated States of Micronesia

Many least-wealthy, rural, remote and resource-poor small island communities are unlikely to benefit from high-profile global water improvement initiatives. Their small landmasses, geologic composition, geography, social and technological isolation, colonial history, and weak educational and financial resources constitute significant barriers to improving access to safe drinking water. This paper discusses the relatively unique position of such island societies in the international community, providing a case study of the Federated States of Micronesia that integrates data and information pertaining to water resources management and governance, spanning from the island village to national scale. A vision is offered regarding the interaction between small island human and biophysical water systems, manifesting ways to pursue water resource development to improve public health which are constructed to be economically, physically and culturally sustainable.

Producer Services Research in the United Kingdom

This paper reviews recent research in the United Kingdom on producer services and suggests directions for further research. A recurrent theme in UK-based geographic research into producer services is the role of service activities, establishments, and trade in uneven development of the UK space economy, a role manifested in uneven provision and quality of services in peripheral regions. During the 1980s, overall growth in demand for producer services and the rapid rise in metropolitan London real estate costs reduced London's dominance, but these trends moderated by the end of the decade. In the absence of adequate government statistics, regular and standardized surveys are needed to compile a time series of service change in the United Kingdom. Directions for continued empirical research include the role of producer services in innovation and technology transfer, the implications of information technology for the location of employment in the sector, and the impacts of productivity increases on employment and wages.     

中国建设用地与区域社会经济发展关系的空间计量研究

利用空间计量模型,对中国大陆地区的30个省、市、自治区2008年的建设用地面积与社会经济发展之间的关系进行了研究。研究表明:30个省、直辖市和自治区地区建设用地面积、GDP、总人口和城市化率都有显著的空间相关特征,一个区域社会经济的发展不仅会驱动自身区域建设用地的扩张,而且会带动邻近区域的建设用地的增长。传统上只从时间维度出发的研究思路,忽视空间维度的相关性和异质性,低估了区域社会经济发展对建设用地增长的作用,必须在普通面板线性回归模型中描述的基础上引入空间变量进行修正。计量模型检验表明,城市化水平对建设用地总规模的影响不甚显著。说明中国大部分省份的农村居民点用地的利用效率普遍偏低。因此,农村居民点用地的调整与优化已迫在眉睫,从长远看来,提高城市化水平,打破城乡二元化的土地制度,建立统一的土地市场,是缓解土地资源紧缺、提高土地利用效率的有效途径。     

淮海经济区协调发展度评价研究

基于区域协调发展的判定标准,构建区域协调发展的指标体系,通过线性加权模型和离差系数法分别计算出淮海经济区经济-社会-人口-资源-环境系统的综合发展水平得分和淮海经济区、苏北鲁南豫东皖北四大板块和20个市的协调度,通过对其分析得出以下结论：（1）淮海经济区处于低经济发展阶段的高协调度阶段;（2）市域协调度多处于中级基本协调阶段;（3）协调度呈现东高西低的空间格局。     

Coastal Massachusetts pond development: edaphic,climatic, and sea level impacts since deglaciation

Kettle ponds in the Cape Cod National Seashore in southeastern Massachusetts differ in their evolution due to depth of the original ice block, the clay content of outwash in their drainage basins, and their siting in relation to geomorphic changes caused by sea-level rise, barrier beach formation, and saltmarsh development. Stratigraphic records of microfossil, carbon isotope, and sediment changes also document late-glacial and Holocene climatic changes.The ponds are separated into 3 groups, each of which follow different development scenarios. Group I ponds date from the late-glacial. They formed in clay-rich outwash, have perched aquifers and continuous lake sediment deposition. The earliest pollen and macrofossil assemblages in Group I pond sediments suggest tundra and spruce-willow parklands before 12 000 yr B.P., boreal forest between 12 000 and 10 500 yr B.P., bog/heath initiation and expansion during the Younger Dryas between 11 000 and 10 000 yr B.P., northern conifer forest between 10 500 and 9500 yr B.P., and establishment of the Cape oak and pitch pine barrens vegetation after 9500 yr B.P. Sedimentation rate changes suggest lowered freshwater levels between 9000 and 5000 yr B.P. caused by decreased precipitation on the Atlantic Coastal Plain. Lake sediment deposition began in the middle Holocene in Group II ponds which formed in clay-poor outwash. These ponds date from about 6000-5000 yr B.P. In these ponds sediment deposition began as sea level rose and the freshwater lens intersected the dry basins. The basal radiocarbon dates of these ponds and stable carbon isotope analyses of the pond sediments suggest a sea-level curve for Cape Cod Bay. Holocene topographic changes in upland and the landscape surrounding the ponds is reconstructed for this coastal area.Group III ponds in the late Holocene landscape of the Provincelands dunes originated as interdunal bogs about 1000 yr B.P. and became ponds more recently as water-levels increased. Peat formation in the Provincelands reflects climatic changes evident on both sides of the Atlantic region.This is the 8th in a series of papers published in this special AMQUA issue. These papers were presented at the 1994 meeting of the American Quaternary Association held 19–22 June, 1994, at the University of Minnesota, Minneapolis, Minnesota, USA. Dr Linda C. K. Shane served as guest editor for these papers.     

北京市郊区传统村落价值评价及可持续利用模式探讨——以北京市门头沟区传统村落的调查研究为例

黄河流域县域交通供给格局及其空间适配性

分析黄河流域交通供给水平特征及其与经济社会发展的空间适配性,对交通资源优化配置、提升交通供需适配性具有重要参考。论文基于黄河流域现状综合交通运输与经济社会基础数据,分析了黄河流域县域交通优势度分异特征,并探讨了交通与县域发展质量的空间适配性。结果表明：黄河流域县域交通优势度有待提升,在人口与GDP方面呈现一定错配特征;高优势度县域集中分布在济南—郑州—西安—兰州通道沿线。黄河流域交通供给均衡性水平高于经济社会差异;样带交通优势度呈现陇海—兰新“一”字型样带>“几”字湾样带>南北纵向“1”字型样带的分布态势,固定资产投资、产业结构、城镇化、经济基础是影响黄河流域县域交通优势度的主要因素。“几”字湾样带和南北纵向“1”字型样带还受到高程、坡度等自然因素的制约;流域40.05%的县域处于初级适配状态,38.78%的县域为交通劣势型,集中在青藏高原、黄土高原沟壑区和内蒙古中西部地区,亟需提升交通设施对该类县域经济社会发展的支撑与保障能力。
