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。     

云南省经济增长与能源消耗的计量模型研究

根据云南省1985~2003年能源消耗的统计数据以及人均GDP统计数据,分析人均GDP与能源消耗之间的相关关系,选取相关性较好的能耗指标(煤炭消耗量、石油消耗量、天然气消耗量、电力消耗量)建立两者之间的计量模型。并在此基础上分析能源消耗与人均GDP增长的关系。经研究发现,云南省经济增长与能源消耗呈类似于EKC的倒U型曲线,且曲线尚未到达转折点,能源消耗量随着经济增长将持续增长。有必要采取有利措施倡导“循环经济”、“绿色GDP”等使曲线走势向良性方向发展。

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。

全国及区域性人均耕地阈值的探讨

论文首先指出并不存在联合国粮农组织提出的人均耕地面积阈值;继而认为人均耕地面积阈值具有鲜明的时间和空间特征,需要有明确的前提条件。为此按1995年的耕地实际生产力(在耕地面积中扣除菜地和经济作物用地面积),以人均400kg、450kg、500kg粮食需求量的生活标准,提出就全国平均而言,人均耕地面积不应小于0.092hm₂、0.104hm₂、0.115hm₂(可以看作当前的人均耕地面积阈值)。根据2010、2030、2050年我国的预期耕地面积以及可能达到的生产能力,按人均400kg、450kg、500kg粮食需求量的生活标准,就全国平均而言,2010年人均耕地面积不应小于0.059hm₂、0.067hm₂、0.074hm₂(可以看作近期的人均耕地面积阈值);2030年人均耕地面积不应小于0.052hm₂、0.058hm₂、0.064hm₂(可以作为中期的人均耕地面积阈值);2050年人均耕地面积不应小于0.046hm₂、0.052hm₂、0.058hm₂(可以作为远期的人均耕地面积阈值)。
