生态系统服务功能及其价值核算

生态系统服务功能是指生态系统服务与生态系统功能的综合，指生态系统与生态过程所形成及所维持的人类赖以生存的自然环境条件与效用，生态系统服务功能对于人类生存发展具有重要的价值，应该在社会经济体系中得以体现，本文探讨了生态系统服务功能的类型，价值核算方法与理论及其应用研究在完善国民经济核算体系、促进可持续发展等方面的重要意义，并对今后发展进行了展望。     

Economic development and environmental protection: an ecological economics perspective

This paper argues on both theoretical and empirical grounds that, beyond a certain point, there is an unavoidable conflictbetween economic development (generally taken to mean 'materialeconomic growth') and environmental protection. Think for a moment of natural forests, grasslands, marine estuaries, salt marshes, and coral reefs; and of arable soils, aquifers, mineraldeposits, petroleum, and coal. These are all forms of 'natural capital' that represent highly-ordered self-producing ecosystemsor rich accumulations of energy/matter with high use potential (low entropy). Now contemplate despoiled landscapes, eroding farmlands, depleted fisheries, anthropogenic greenhouse gases,acid rain, poisonous mine tailings and toxic synthetic compounds.These all represent disordered systems or degraded forms of energy and matter with little use potential (high entropy). The main thing connecting these two states is human economic activity. Ecological economics interprets the environment-economyrelationship in terms of the second law of thermodynamics. The second law sees economic activity as a dissipative process. Fromthis perspective, the production of economic goods andservices invariably requires the consumption of available energy and matter. To grow and develop, the economynecessarily 'feeds' on sources of high-quality energy/matter first produced by nature. This tends to disorder and homogenizethe ecosphere, The ascendance of humankind has consistently been accompanied by an accelerating rate of ecological degradation, particularly biodiversity loss, the simplificationof natural systems and pollution. In short, contemporary political rhetoric to the contrary, the prevailing growth-oriented global development paradigm is fundamentally incompatible with long-term ecological and social sustainability. Unsustainability is not a technical nor economic problem as usually conceived, but rather a state of systemic incompatibilitybetween a economy that is a fully-contained, growing, dependent sub-system of a non-growing ecosphere. Potential solutions fly inthe face of contemporary development trends and cultural values.     

Incorporating natural capital into economy-wide impact analysis: a case study from Alberta

Traditionally, decision-makers have relied on economic impactestimates derived from conventional economy-wide models. Conventional models lack the environmental linkages necessary for examining environmental stewardship and economic sustainability, and in particular the ability to assess the impact of policies on natural capital. This study investigatesenvironmentally extended economic impact estimation on a regionalscale using a case study region in the province of Alberta knownas the Foothills Model Forest (FMF). Conventional economic impactmodels are environmentally extended in pursuit of enhancingpolicy analysis and local decision-making. It is found that theflexibility of the computable general equilibrium (CGE) modelingapproach offers potential for environmental extension, with a solid grounding in economic theory. The CGE approach may be the tool of the future for more complete integrated environment andeconomic impact assessment.     

2000年北京大气中SO2浓度削减50%的健康效益—人力资本法实例研究

人力资本法是评估环境污染健康损害价值（或治理污染的健康效益）的常用方法，但在发达国家，它逐渐被隐含价格法等所取代。本文通过实例研究，探讨了人力资本法在我国目前的适用性，研究结果表明，当使用流行病学关于疾病负担的计量方法（ＹＰＬＬ）时，人力资本法在我国有很大的适用性。     

环境污染对人群健康影响评价及其经济损失估算

为了定量地描述环境污染对人群健康的危害及其相应的经济损失，本文认为应对健康风险评价和人力资本法作进一步的研究，以便给出统一的规范化评价程序和计算方法。文中还对有关内容作了简要介绍。

基于模糊综合模型的收费高速公路投资风险评估研究

我国高速公路存在着运行效率低下、收费标准较高、管理混乱、浪费严重、投资成本居高不下、财务状况难以为继等问题,不少项目存在着十分严重的银行金融风险和地方财政隐患,而高速公路投资的风险评估却基本上还是空白,因此,对高速公路投资风险进行评估具有重要意义。笔者认真分析了收费高速公路投资风险的特点,重点提出了风险评价指标体系,并建立了收费高速公路投资模糊综合评价模型。     

我国证券市场体制性缺陷与投资风险分析

与国民经济长期高增长相背离,证券市场出现了深幅下跌,投资者承受了巨大的投资风险,究其原因,体制性缺陷是重要因素之一。笔者认为,我国证券市场的体制性缺陷主要表现在市场经济环境不够完备、法律法规体系不十分健全、监管体制不力、证券市场的功能定位扭曲、股权分置问题久拖难决等方面。目前该体制性缺陷是导致我国证券市场长期下跌的重要原因,也给证券投资者带来了巨大的投资风险。只有加快改革、完善法律和监管体制,我国证券市场才能具有投资价值并健康发展。     

Ecosystem services assessments in local municipal decision making in South Africa: justification for the use of a business-based approach

The ecosystem services (ES) concept is being increasingly incorporated into environmental policy formulation and management approaches. The Corporate Ecosystem Services Review (ESR) is a framework used to assess the dependence and impact that a business has on ES. The success of the corporate experience of ES assessment provides an opportunity for adaption for local authority decision making. In this paper, the ESR tool was adapted to the South African setting at a local government level, and tested at two sites in the Msunduzi Municipality, KwaZulu-Natal. In testing the tool and gathering feedback from key stakeholders, it was found that there are both opportunities and challenges to this approach. Overall, however, it provides an opportunity for the systematic inclusion of ES assessment into existing regulatory frameworks for land-use planning and Integrated Environmental Management, whether in a strategic application, at a broader spatial (municipal) scale or in a specific locale within the municipality.
