实现传统经济向生态经济的转变

认为生态环境危机的出现，归根结蒂，在于人类社会的价值观存在着重大的错误以及由此而采取的经济发展模式存在着重大的错误；要缓解生态环境危机，人类社会必须改变价值观，改变经济发展模式，实现传统经济向生态经济的转变，走可持续发展的道路；为了实现这种转变，人类在经济活动中，必须遵循生态经济规律，建立企业生态经济管理模式，合理利用资源，优化产业结构，重视经济效益、社会效益和生态效益的协调和统一。文章还认为，为了实现这种转变，从联合国到个人，各国政府、各种组织、各行各业，都必须行动起来，参与生态经济建设。最后提出和讨论了生态经济学今后应该加强研究的几个问题。     

环境恶化与保护的经济分析

分析了环境恶化的根源不在于环境本身，而在于当今引导人们经济活动的经济体系，特别是其中的价格体系没有全面准确地反映出环境的各种价值（包括经济价值、生态价值和社会价值）。致使人类社会无代价地滥用资源并破坏环境。提出了加强保护的经济措施就在于运用环境经济规律和生态规律对当今不完善的经济体系进行全方位的修正。

Contribution of national bioassessment approaches for assessing ecological water security: an AUSRIVAS case study

River managers in Australia are managing in the face of extremes to provide security of water supply for people, production and the environment. Balancing the water requirements of people, environments and economies requires that water security is viewed holistically, not just in terms of the water available for human consumption. Common definitions of water security focus on the needs of both humans and ecosystems for purposes such as drinking, agriculture and industrial use, and to maintain ecological values. Information about achieving water security for the environment or ecological purposes can be a challenge to interpret because the watering requirements of key ecological processes or assets are not well understood, and the links between ecological and human values are often not obvious to water users. Yet the concepts surrounding river health are inherently linked to holistic concepts of water security. The measurement of aquatic biota provides a valuable tool for managers to understand progress toward achieving ecological water security objectives. This paper provides a comprehensive review of the reference condition approach to river health assessment, using the development of the Australian River Assessment System (AUSRIVAS) as a case study. We make the link between the biological assessment of river health and assessment of ecological water security, and suggest that such an approach provides a way of reporting that is relevant to the contribution made by ecosystems to water security. The reference condition approach, which is the condition representative of minimally disturbed sites organized by selected physical, chemical, and biological characteristics, is most important for assessing ecological water security objectives.     

Evaluating eco-sustainability and its spatial variability in tourism areas: a case study in Lijiang County,China

Studying eco-sustainability of tourism areas is part of sustainable development research. In tourism areas, the ecosystem comprises both the environment and the human system. The environmental system is basically physical, whereas the human system, consisting of both tourists and residents, is the dominant factor driving ecosystem change. If the combined influence of tourists and residents exceeds the carrying capacity of the environment, which is the ecological threshold of eco-sustainability in the tourism area, then the structure, function and stability of the environment will degenerate. Hence, eco-sustainability assessment of tourism areas should be based on analyses of the relationship between the influence of tourists and residents on the environment and the environmental carrying capacity. Using ecological footprint and tourism ecological footprint models, we developed and applied a synthetic assessment index system for eco-sustainability of tourism areas in Lijiang County, Yunnan Province, China, to conduct a quantitative spatial assessment for 2001. The eco-sustainability of Lijiang was high, with a harmonious relationship between regional socioeconomic development and the ecological environment. There were significant spatial differences in eco-sustainability among 24 towns in the region because of spatial heterogeneity in socioeconomic status, tourism development and environmental elements.     

无锡市水环境变化及其引发的地质灾害问题与对策

随着经济的快速发展，无锡市水环境质量发生了很大的变化。由于在太湖、五里湖等湖泊周围大规模围湖造田，水域生态环境和原有水系格局被破坏，五里湖、梅梁湖水质恶化，每10年下降一个等级，太湖水质总体上呈现富营养化状态。水环境变化在一定程度上导致了地面沉降的发生，有的地区地下水位呈加速下降的趋势，有的地区已出现多个地下水位降落漏斗，后者面积达220km^2。应该加快区域供水建设步伐，调整工业结构，加强对水资源的管理和调控。

种群水平生态风险评价方法概述及其在环境管理中的应用

生态风险评价的目的是保护生态系统功能的完整性、稳定性和持久性,为环境风险管理提供理论依据。然而,目前常见的用于保护生物的化学污染物浓度阈值大多是以个体水平的毒性试验结果为基础,忽略了物种在时间和空间相互作用等因素,不能够完全保护生态环境安全和生态系统功能的延续性。本文从生态风险评价的概念、目的和意义引出种群水平生态风险评价在环境管理应用的重要性,综述了种群水平生态风险评价的科学问题(如密度依赖、遗传变异和空间结构等),归纳了种群水平风险评价主要模型方法及其应用(如Euler-Lotka方程、预测矩阵、个体模型、空间模型和动态能量预算模型等),列举了各国现有法律法规中关于种群水平生态风险评价的规定,以期为种群水平生态风险评价方法研究及在环境管理中的应用提供有益借鉴。

Integrated ecological assessment as the basis for management of a coastal urban protected area: A case study of Xiamen,China

In the process of rapid urbanisation in China, environmental problems have increased, from sewage discharge to climate change. Marine protected areas (MPAs) are widely advocated as a means to comprehensively manage human activities and resources in ocean and coastal areas. However, MPAs only safeguard populations or assemblages within their boundaries and fail to offer any protection from many major threats to marine environments. An increase in environmental threats implies an increase in environmental management and assessment. We propose a methodological framework for integrated ecological assessment using the Xiamen marine protected area as a case study. The integrated ecological assessment framework can be generalised from the dimensions of environment, economy, society and institution. Surveys were undertaken to assess the state of the Xiamen coastal environment, the resources of the reserve, and issues associated with human activities. Stakeholders were interviewed about their attitudes towards issues regarding the management of the reserve. The constraints of the reserve management were identified. The methodological framework is presented as a tool to help identify relative ecological security in order to prioritise actions and assess the ecological implications of management and policy decisions.

Ecological network and emergy analysis of urban metabolic systems: Model development,and a case study of four Chinese cities

Analysis of the structure and function of urban metabolic systems is an important goal of urban research. We used network pathways and network utility analysis to analyze the basic network structure of the urban metabolic system and the complex ecological relationships within the system, providing a new way to perform such research. Using four Chinese cities as examples, we developed an ecological network model of the urban metabolic system. By using network pathway analysis, we studied the changing relationships between metabolic length and the number of metabolic pathways, and between metabolic length and reachability. Based on the distribution of the number of metabolic pathways, we describe the basic structure and intercompartment relationships of the system. By using the sign distribution in the network utility matrix, we determined the ecological relationships and degree of mutualism between the compartments of the system. The basic components of the system consisted of the internal environment, the external environment, and the agricultural, industrial, and domestic sectors. With increasing metabolic length, the ecological relationships among the components of the system became more diverse, and the numbers of metabolic paths and their reachability improved. Although the basic network structure of the four cities was identical, the mutualism index differed. Beijing's mutualism index was superior to that of Shanghai, and much higher than those of Tianjin and Chongqing. By analyzing the structure and function of the urban metabolic system, we provide suggestions for optimizing the structure and adjusting the relationships, and propose methods for the application of ecological network analysis in future urban system research.
