Previous studies on river health evaluation mainly focused on characterizations at a river-corridor scale and ignored the complex interactions between the river ecosystem and other components of the river basin. Based on the consideration of the interactions among rivers, associated river basin and habitats, an assessment framework with multi-scale indicators was developed. An index system divided among these three scales to characterize the health of river ecosystems in China’s Liao River Basin was established. Set pair analysis was applied to integrate the multi-scale indicators and determine the health classes. The evaluation results indicated that the rivers in the western and eastern zones of the Liao River were classified as sick, and rivers in the main stream of the Liao and Huntai rivers were classified as unhealthy. An excessive level of disturbances, such as large pollution loads and dense construction of water conservation projects within the river basin, were the main causes of the river health deterioration. 相似文献

This paper examines sustainable entrepreneurship over time by focusing on the identification of the combinations of environmental factors (clean water and sanitation, affordable clean energy, urgent action to combat climate change, and life on land) and economic development factors (decent work and economic growth). Based on data from 50 countries, it examines the causal configurations behind the manifestations of these factors using fuzzy‐set qualitative comparison analysis. The variables and data were derived from the Global Entrepreneurship Monitor and the Sustainable Development Goals Index. Our key finding is that protecting and sustainably using terrestrial ecosystems always have a sufficiently positive effect to ensure a high level of sustainable entrepreneurship. Also, high levels of sustainable use of terrestrial ecosystems and sustainable growth and decent work, plus good access to affordable and sustainable energy and clean water are related to promote sustainable entrepreneurship. 相似文献

基于多区域投入产出法的广东省水足迹研究 总被引：1，自引：0，他引：1
在人类活动和气候变化的影响下,广东省面临日益严峻的水资源危机。水足迹反应了生产人类消费的物品和服务所消耗的水资源总量,为缓解广东省水资源危机提供了新视角。文章基于多区域投入产出法与2007年的社会经济统计数据,研究广东省的水足迹,结果显示,（1）2007年广东省的水足迹为316.4亿m3,其中本地水足迹占64.1%、外来水足迹占35.9%。（2）从产业水足迹看,第一产业虽然消费需求最小,但相应的水足迹最大,广东省的外部水足迹主要来源于该产业;第三产业的消费需求最大,但水足迹相对较小,各省市通过该产业输入广东的水足迹普遍较小。（3）在空间上,广东省的外来水足迹主要来源于湖南、广西、湖北和贵州等省区,且各地输入广东的水足迹随距离增大呈减小趋势。（4）从产业用水看,第一产业的完全用水系数最大,以直接用水为主;第二、三产业以间接用水为主。因此,提高农林牧渔业等水足迹较大行业的外部供给比例、积极扩大水足迹较小的第三产业消费需求,通过优化产业结构、提高产业链各环节用水效率,加强与水资源充沛省市的贸易,可缓解广东水资源危机,实现经济发展与水资源安全双赢。 相似文献

Conservation of historic buildings and streets through rehabilitation is growing rapidly in many countries. The extent to which this approach is conducive to the aims of social sustainability has yet to be investigated. This study examines the attributes and factors that contribute to socially sustainable development in the rehabilitation of historic districts. A historic district in Shanghai, China, is used as a case study. The study area, Tianzifang, is a community‐initiated rehabilitation, which has conserved traditional residential houses and old factories and transformed them into a community for creative industry. Site observations, personal interviews and questionnaire surveys of public opinion were conducted to examine the contributing factors. Through a literature review, fieldwork and a pilot study, 21 factors were identified as contributing social sustainability to the rehabilitation of historic districts and form the basis of the analysis of the case study and the opinion survey exercise. Through factor analysis, the underlying social sustainability factors that embrace the 21 attributes were derived. In order of importance, the social sustainability factors are ‘Maintain good physical condition to fulfill educational role’, ‘Provide public involvement opportunities’, ‘Enhance sense of place and local culture’, ‘Enhance cultural identity and collective memory’ and ‘Retain significant meanings and associations to the community’. This study presents a framework to understand the underlying factors for socially sustainable rehabilitation of historic districts, which provides insights for professionals and communities to design and implement rehabilitation strategies. The framework also provides a reference to examine other complex heritage sites worldwide. Copyright © 2011 John Wiley & Sons, Ltd and ERP Environment. 相似文献

A newly developed agent-based framework for modeling, simulation, and evaluation of resource management in self-sustainable human settlements is presented, along with the ability of the framework to prolong the self-sustainability of the observed human settlement system in the simulation environment. In this study the focus is on the analysis of a conducted water management simulation based on observations of an existing eco-village in Croatia, in the context of producing, storing, and consuming water as a resource. The conducted research shows that the developed framework was able to prolong the self-sustainability of localized water production, storage, and consumption dynamics when managing the water allocation with the use of self-sustainability mechanisms, in comparison to water management without using such mechanisms, under the same initial conditions. The work is placed within the context of sustainable development, Internet of Things, as well as Environmental Internet of Things areas of research, analyzing the ambiguous relationship between the terms ‘sustainable development’ and ‘self-sustainability’. 相似文献

An integrated multi-criteria analysis framework was proposed for the sustainable water management of built reservoir with dam-heightening-based decision, which enhances the conventional decision-making methods by more reasonably quantifying the decision-making process. The method utilizes a group of techniques involving game theory, analytic hierarchy process (AHP) identifying and considering different stakeholder groups, entropy weight, and fuzzy comprehensive evaluation (GAEF), and is applied to the largest water transfer programs in China. The study results showed that the improved multi-criteria decision framework can well deal with the decision-making problem of built reservoir construction scheme in facing the newly increased task of water transfer. The study identifies five stakeholders that affect the subjective weight of the heightening schemes of built reservoir for inter-basin water transfer. It was revealed that the game theory can better couple the collective wisdom of large complex groups and the objectivity of indicators than traditional methods such as geometric average. This study is of high reference value for the feasibility demonstration of built reservoir with dam-heightening-based decision around the world to achieve the water related Sustainable Development Goals (SDGs), especially for those reservoirs with water transferring tasks. 相似文献

Strategies for the management of cultural heritage resources within a sustainable development concept framework are examined. In line with the 1992 Rio Declaration principles of sustainable development, the paper suggests sustainability principles relating to community participation as more relevant for the field of cultural heritage resource management in Botswana. The article illustrates this relevance by exploring and drawing out production and consumption indicators of cultural heritage resources in both their tangible and intangible composition. It concludes that participation principles of sustainable development are more applicable as a point of departure towards integration of sustainability into cultural heritage resource management as communities are carriers and immediate custodians of cultural resources in Africa. Conservation processes that set limits of acceptable change for resource use are suggested within a modified framework that links community interaction with cultural resources at both social and resource management levels.

SUMMARY The notion of sustainable development in the context of water resources is discussed. Facing the increasing pressures — population growth with consequences for settlements and production of food and fibre, and human aspirations to better living standards — the business-as-usual approach to water development and management cannot he globally sustainable. The need for curbing water demands and for ‘doing more with less’ are gaining growing recognition in our increasingly thirsty planet. An integrated approach to freshwater resources is needed, based on the perception of water as a natural resource, part of the ecosystem, and an economic and social good. It is discussed how hydrological extremes jeopardize sustainable development. Sustainability-related properties of drought and flood preparedness and mitigation measures are reviewed. Even if the term ‘sustainable development’ has been typically used in a qualitative sense, in order to compare how different options (e.g. flood protection alternatives) fare with regard to sustainable development, one needs at least rough quantitative measures. A sample of relevant indices is reviewed. It is advocated that hydrological observations should be recognized as an essential component of sustainable development and management of water resources. 相似文献

To improve material efficiency, industrial structure optimization becomes a focal point in Chinese industrial and environmental policies. It is crucial to cluster economic sectors and determine their priority for industrial and environmental policy implementation. Integrating a set of criteria, a hybrid input-output model and the hierarchical cluster analysis, this study clusters China’s economic sectors and determines their priority on a life cycle basis. China’s economic sectors are clustered into three clusters. Industrial structure changes (industrial policy) should encourage the development of sectors in cluster 1 and limit the development of sectors in cluster 2. Technology development and materials recycling (two environmental policies) should mainly focus on sectors in clusters 1 and 2. Future industrial policies in China should limit the development of two sectors named Manufacture of metal products and Extraction of petroleum and natural gas. Instead of limiting some industries by command-and-control, the best policy option is to remedy environmental standards and law enforcement. Enterprises belonging to the identified key sectors from the viewpoint of direct production impacts should be concerned to achieve enterprise sustainability. To achieve sustainable production chains, the identified key sectors from the viewpoint of accumulative production impacts should be concerned. For sustainable consumption, the identified key sectors from the viewpoint of consumption impacts should be concerned to transform consumption styles. Most of environmental pressure can be alleviated not only by technical improvements and material recycling, but also by the development of economic sectors in cluster 1. 相似文献
