"分裂的全球化"与人类的可持续发展

经济全球化一方面推动了世界各国的合作，另一方面拉大了发达国家与发展中国家的差距。全球化进程中这种强弱群体的分化，实质上是一个“分裂的全球化”。它给人类的可持续发展带来了极大的挑战。全球化是人类发展不可逆转的方向。同时，可持续发展是人类社会共同的目标。只有解决分裂的全球化，人类才能实现可持续发展。     

生态福利绩效视角下的上海市可持续发展评价研究

资源与环境约束加剧的大背景下,在"生态门槛"内实现社会福利最大化的可持续发展模式是未来城市发展的必然选择。从生态福利绩效视角出发,选取人均生态足迹和人类发展指数构建城市可持续发展评价指标体系,并采用DEA方法计算二者的投入产出效率,对上海市1999~2012年可持续发展水平进行多维度、动态化的实证分析。研究发现:1上海市人类发展指数、人均生态足迹与经济发展同步增长,但人均生态足迹水平大于生态承载能力,处于严重"生态赤字"状态,并不断恶化;2上海市多数年份的生态福利绩效处于DEA无效状态,且2005年以来进入规模收益递减通道。最后提出政策建议。     

基于可持续发展战略的生态竞争力评价——以安徽省为例

生态资源与经济发展的关系是人类长期关注的热点问题之一。生态竞争力是指一个区域内的生态资源支撑其经济社会可持续发展所具备的资源优化配置的能力,是社会经济发展的基石。依据可持续发展理论,借鉴和参考相关生态环境及区域经济等评价指标体系,建立了以生态环境现状、生态环境压力和主动协调能力3个方面为二级指标的生态竞争力评价指标体系,并以安徽省原17个市为例,运用主成分分析和算术平均法等方法,对各市生态竞争力进行排名和系统分析。初步构建了以生态竞争力为评价指标体系的方法,其结果可为安徽省各市生态建设和经济发展提供科学依据和决策参考     

An approach to sustainable development: the case of Cuba

This paper analyzes the Cuban model of sustainable development and explains the causes that made Cuba the only country that meets the conditions of sustainability according to the Worldwide Fund for Nature (WWF). The Human Development Index has three main components: quality of life (health indicator measured as life expectancy at birth), knowledge (education indicator measured as adult literacy) and the standard of life (economic indicator measured by the Gross Domestic Income). This paper analyses the aspects of the educational and health system of Cuba and also of its energy policies that explain the excellent scores of the Human Development Index. Cuba shows a Human Development Index of 0.8 with an Ecological Footprint of 1.8?gha. This is achieved with a Gross Domestic Income lower than other countries with similar Human Development Index. The Ecological Footprint of Cuba is mainly determined by the CO₂ and the agricultural land footprint. The paper shows how the economic transition, after the economic crisis of the early 1990s, was realized without significantly increasing the Ecological Footprint.     

生态足迹研究述评

自然资源是人类赖以生存的物质基础，人类活动必须限制在环境资源承载力的值范围之内，传统的资源利用评价方法存在着考虑不全面、计算复杂、可操作性差等不足，因而有必要从生态系统本身的功能出发对人类活动的可持续性进行评价，生态足迹提出于20世纪90年代，是一种新颖的资源利用评价方法，它计算简明，对地区可持续发展决策具有一定的指导性，迄今为止，人们已在不同尺度上开展了大量相关研究，本文介绍了生态足迹的基本概念和进展，度评述了该方法的优点及不足，最后对今后的研究做出了展望。     

新疆城市化进程中生态预警研究

对新疆城市化进程中的生态环境进行预警研究,目的是在城市化引起生态环境退化之前,以便能及时采取防范措施。构建城市化生态质量评价指标体系和可拓学评价模型,利用灰色预测模型对新疆2010～2014年的生态质量评价指标进行预测,对新疆2005～2014年城市化生态质量进行分析。研究表明：2005～2014年,资源子系统经历改善-恶化-改善的过程,生态子系统先改善后恶化,环境子系统不断改善,总体上,城市化生态质量不断改善。因此,新疆城市化进程中,应当控制人口增长,节约水资源,保证充足的水资源量和生态用水量;节约居民和工矿用地,保护绿洲,提高森林覆盖和森林病虫害防治;不断提高环境污染治理投资,减少工业三废的排放等,使城市化与生态环境耦合系统处于协调状态     

基于湖泊形态分析的旅游开发适宜性评价——以大梁子湖为例

在旅游开发建设压力下,湖泊生态环境面临巨大挑战。湖泊旅游开发适宜性评价鲜少从湖泊形态入手,而湖泊形态参数所揭示的湖泊水文特征会在一定程度上对旅游开发造成影响。以GIS技术为工具,选取大梁子湖分形几何维数和欧式几何形态指标（岸线发育系数、形状率、近圆率、紧凑度、空间包容面积）作为湖泊形态参数,通过Mapgis软件分析,获得大梁子湖湖泊形态分形维数为1.549,同时进一步计算出构成大梁子湖的6大湖泊的欧式几何形态指标,以此构建基于湖泊形态的旅游开发适宜性评价指标体系,建立湖泊形态和旅游开发适宜性关系模型,揭示湖泊水文特征与景观吸引力、生态脆弱程度、旅游环境安全性以及游客环境容量等旅游开发适宜性指标的内在联系,为湖泊旅游开发决策提供科学依据     

基于本地生态足迹模型的浙江省可持续发展评价

Shifting role of ecology in solving global environmental problems: selected practical tools

As environmental issues changed its focus from pollution and endangered species to fulfilling basic human needs, such as health, education, shelter, sanitation, hygiene, on the one hand and social justice on the other hand, it widened in its scope. People questioned about adequacy of ecological knowledge in solving daily questions in their life, and also contribution of their values, objective life situations and idea of quality of life for ecological well-being. Two core and complimentary values strongly emerged from the concept of sustainable development; namely environmental protection and justice. Unfortunately, there is lack of awareness on dimensions of human life and its linkages with the wider environment. To combine the values, dimensions of human life and its linkages with external environment, fundamental changes in human behaviour for human development is required. Present article reflects on dimensions of life, essential skills and practical tools for environmental protection and human development.     

Ecological Sanitation--a way to solve global sanitation problems?

Today about 2.4 billion people in rural and urban areas do not have access to adequate sanitation services. Within 20 years, it is expected that an additional 2 billion will live in towns and cities, mainly in developing countries, demanding sanitation. Still over 90% of sewage in developing countries is discharged untreated, polluting rivers, lakes and coastal areas. Conventional sanitation concepts, based on flush toilets, a water wasting technology, are neither an ecological nor economical solution in both industrialized and developing countries. The water-based sewage systems were designed and built on the premises that human excreta are a waste; suitable only for disposal and that the environment is capable of assimilating this waste. A sanitation system that provides Ecological Sanitation (EcoSan) is a cycle--a sustainable, closed-loop system, which closes the gap between sanitation and agriculture. The EcoSan approach is resource minded and represents a holistic concept towards ecologically and economically sound sanitation. The underlying aim is to close (local) nutrient and water cycles with as less expenditure on material and energy as possible to contribute to a sustainable development. Human excreta are treated as a resource and are usually processed on-site and then treated off-site. The nutrients contained in excreta are then recycled by using them, e.g., in agriculture. EcoSan is a systemic approach and an attitude; single technologies are only means to an end and may range from near-natural wastewater treatment techniques to compost toilets, simple household installations to complex, mainly decentralised systems. These technologies are not ecological per se but only in relation to the observed environment. They are picked from the whole range of available conventional, modern and traditional technical options, combining them to EcoSan systems. The paper presents an introduction to EcoSan principles and concepts including re-use aspects (available nutrients and occurring risks), and case studies of EcoSan concepts in both industrialized and developing countries.     

重庆市景观格局动态变化分析

土地利用/覆盖变化是全球变化研究中的一个重要环节,景观生态学是土地利用/覆盖变化的一个重要的研究手段。以分形理论为指导,利用景观生态学的相关指标,在遥感和地理信息技术的支持下,研究重庆市景观格局的变化。采用1995和2000年Landsat TM/ETM影像为基础数据,提取并建立土地利用空间数据库,应用景观空间格局分形模型,获取景观类型的分形维数和稳定性指数以及景观多样性指数、分离度指数、破碎度指数、均匀度指数和优势度等指标。结果表明：水田、旱地、水域等土地类型的分形维数在研究时间段内有明显上升,有林地、灌木林地和草地等景观要素类型的分形维数降低;景观多样性和破碎度指数以及均匀度略有增加,而优势度指数下降;分形维数和破碎度指数呈极显著正相关。最后为重庆市景观格局的持续发展提出了若干建议。     

Moving towards urban sustainability in Kenya: a framework for integration of environmental,economic, social and governance dimensions

Global urban development is increasingly becoming an aspect of focus as nations fight sustainability challenges. A review of the current literature on urban sustainability suggests that research on development of cities, in both developed and developing countries, is growing fast, with an emphasis on sustainable development. However, very little of this research contains an integrated framework to systematically identify and examine the various dimensions of urban sustainability and to measure and evaluate them appropriately. Cities are more than the sum of their sectors, and are complex and interdependent systems on whose dynamics the quality of life of millions of human beings and a good part of the economy depend. Environmental, economic, social and governance problems can create formidable barriers to urban sustainability. Governance remains a critically important dimension of urban sustainability, especially when discussing urbanization in developing countries, given rapid population movements and imbalances in socio-economic development. Understanding how cities function is fundamental to resolving these imbalances. The aim of this paper is to provide a review and analysis of the concept of urban sustainability and to propose the development of a holistic framework through integration of environmental, economic, social, and governance dimensions of sustainability. Such a review would make it possible to understand the complex dynamics of the four dimensions and to assess the progress and challenges in moving towards urban sustainability, taking the case of Nairobi, Kenya, as an example. The paper argues that, for urban sustainability in developing countries, more emphasis should be placed on the governance dimension, because this is where the biggest challenge exists, with increasing needs for immediate management of rapid urbanization.     

全球绿色低碳发展与公平的国际制度建设

在可持续发展和扶贫框架下发展绿色经济与国际可持续发展制度建设及改革是当前世界可持续发展的核心和关键,也是"里约+20"峰会的两个主题。首先,绿色经济是体现经济社会与资源环境相协调和可持续发展的根本途径。绿色经济的核心是以低的自然资源消费、低排放、低污染,达到高的自然资源利用效益,实现高的经济社会发展水平,提供高的生活水平和优良的生活环境。全球绿色经济的发展潮流,将引发社会形态由"工业文明"向"生态文明"转变。虽然经济发展和消除贫困是发展中国家当前首要和压倒一切的优先任务,但也必须探索新型的绿色低碳工业化和现代化道路,在实现工业文明的过程中,努力建设生态文明,实现跨越式发展。同时积极应对全球绿色低碳转型中新的经济、贸易、技术竞争规则和格局的变动,加强先进技术创新,提升自身的低碳竞争力。其次,公平获取可持续发展的理念,应成为国际可持续发展制度建设和改革的基本原则。可持续发展要求既要促进经济社会发展与资源环境相协调,促进"代际公平",又要关注欠发达地区消除贫困,提高生活质量,改善生态环境,实现"国别公平"、"人际公平"。因此,国际可持续发展制度框架的建设和改革,要体现世界各国公平获取可持续发展的理念和原则,全面均衡地反映不同国情和发展阶段国家的利益诉求。主要表现在公平享有全球环境空间、公平获得现代优质能源服务、公平适应全球环境变化、公平承担责任义务及公平的国际制度和机制。中国需要统筹国内外两个大局,走中国特色的绿色低碳发展之路。最后,中国的国情和发展阶段特征,在可持续发展领域又面临比发达国家更多的困难和更严峻的挑战。在全球发展绿色经济,努力实现可持续发展的大背景下,中国要统筹国际国内两个大局,协调推进。在国际上积极参与国际制度的建设和改革,在促进全球经济发展,社会进步和环境保护等方面发挥积极的建设性的作用。在国内加强可持续发展战略的实施,走绿色、低碳和可持续发展的路径。主要战略对策包括加速转变发展方式,强化节能优先,控制能源消费总量和CO2排放总量的过快增长;加强能源结构的低碳化,逐步建立并形成以新能源和可再生能源为主体的可持续能源体系;加强城乡统筹,地区平衡,促进生态城市建设;适应国际可持续发展制度改革的趋势,加强绿色低碳和可持续发展的制度建设;抓住机遇,顺应世界绿色低碳发展潮流,自主实现发展方式的转变,把传统的资源依赖型、粗放扩张的发展方式转变到新型的技术创新型、内涵提高的发展方式上来,基本走上绿色低碳和可持续发展的轨道。     

全球可持续发展面临的挑战与对策

全球可持续发展涉及可持续经济、可持续环境和可持续社会三方面的协调统一,要求人类在发展中讲究经济效率、关注环境和谐与追求社会公平,最终达到人的全面发展。自1992年联合国环境与发展大会以来,国际社会积极推动实施《关于环境与发展的里约宣言》、《21世纪议程》和《可持续发展首脑会议执行计划》,各种形式的国际和区域环发合作深入开展,各个国家为促进可持续发展付出了巨大努力,在消除贫困和实现千年发展目标方面取得一些成绩。但是,全球在经济、环境和社会发展方面正在面临着越来越复杂的形势,全球可持续发展事业依然面临严峻的挑战。本文从经济、环境与社会三个方面,系统分析了全球可持续发展面临的挑战。分析表明:全球经济发展依然不平衡,不稳定性在加大,而且世界贫富差距明显,发达国家对发展中国家的官方援助不足;全球能源结构没有根本性改变,CO2排放不断增加,气候变化问题突出,而且一些国家生态环境问题较为严重;世界总人口数不断增加,各国就业水平难以提高,各国教育水平非常不均衡,而且欠发达国家人均医疗卫生支出水平低,居民健康状况堪忧。针对全球可持续发展面临的挑战,本文提出了相应的对策:①坚持"共同但有区别的责任"原则。可持续发展没有统一的模式,各国的发展阶段、条件和能力的不同必须予以正视;要区别发达国家和发展中国家的不同国情,要充分尊重发展中国家的发展权利;要为发展中国家向可持续发展转型提供技术、资金和能力建设方面的强有力支持。②加强各国政府在环境领域的交流与合作。不仅要重视全球性环境问题,而且更要优先考虑区域性环境问题,特别是发展中国家和最不发达国家面临的生态环境问题。③积极推动全球社会朝向均衡、普惠和共赢的方向发展。世界上所有国家都应有权以平等的身份参与全球治理过程以及不断改进和优化治理机制,而且全球治理结构应该向发展中国家倾斜;要积极消除贫困、减少不平等现象、使增长具有包容性、使生产和消费更可持续;要增强人们做出可持续选择的权利,特别是妇女、年轻人、失业者以及社会最弱势和最脆弱群体的权利等。     

Quantitative Appraisement on Ecological Carrying Capacity in Coastal Rapid Developing Region of Hainan Province

Abstract

The ecological carrying capacity, an important indicator to evaluate the sustainable development of the ecosystem, means the potential ability of the natural ecosystem to carry socioeconomic development while the ecosystem is healthy. It is limited by the carrying capacity of natural resources and environment and the elasticity of the ecosystem. It will be greatly significant to study the ecological carrying capacity of Hainan Province, the first ecological province admitted by the State Environmental Protection Administration in China. Not only is the natural ecosystem reflected, but also the effects of human activities are emphasized by integrating the ecosystem health analysis into the ecological carrying capacity research. The research results, using the Factor Analysis tools of software SPSS, indicate that the ecological carrying capacity of Hainan Province fluctuated obviously from 1996 to 2005. The level of the ecological carrying capacity of Hainan Province was relatively high in 1996, and reached into trough from 1997 to 1999. It has steadily ascended to be above the middle level since the 21st century. The results also show that policy factors, especially the implementation of the ‘Ecological Province’ strategy, were important driving forces to influence the ecological carrying capacity. With the population rapidly increasing, the land and water resources per capita have decreased quickly. The amount of the ecological carrying capacity was promoted remarkably by socioeconomic development especially economic growth and technology applications. All of these will provide useful suggestions to establish and enact regional development policies, especially for protecting and reconstructing the ecology and environment of Hainan Province.
