城市生态系统的评价在生态城市规划中的应用(英文) 总被引:1,自引:0,他引:1
本文通过两个实例来说明不同的城市生态系统评价方法在生态城市规划中的应用。在天津市生态足迹研究中,计算得知全市2003年人均生态足迹和生态承载力分别为2.12公顷/人和0.33公顷/人,生态赤字高达1.79公顷/人,因此在其生态城市建设规划中提出了相应的能源和生物资源高效利用措施;在石家庄市生态系统健康评价中,评价了其2001年~2005年的生态系统健康水平。结果表明,生态系统在2001年处于病态,在后4年内处于亚健康状态。规划中提出了使生态系统向着健康有利方向发展的对策建议。 相似文献

在明确房地产业生态系统运行机制及健康内涵后,构建了基于PSR模型的评价指标体系,运用熵权TOPSIS法对武汉市2001-2012年房地产业生态系统健康状况及系统协调度进行了分析。研究结果表明:以2008年为分界点,在此之前,区域房地产业生态系统健康综合指数波动性较大,此后逐渐趋缓,但总体水平还有待提高,2012年房地产业生态系统仅处于"偏冷亚健康"状态;压力、状况和响应三个子系统间虽然保持较高协调性,但需注意系统内部结构调整与优化,避免协调度"虚高"现象。 相似文献

The transformations taking place in Poland aim, among others, at adapting the system to new conditions of a market economy. The irrationality of funding social services by the budget made it necessary to restrict the role played by the State in their funding. It means the need for changes concerning not only institutional reforms but also new sources of income. The goal of this paper is to present the main directions of reforms occurring in the Polish economy on the example of health care. The paper concentrates on the problems of implementation, the reform in health care, its reasons and consequences. The trends indicate that the process of reforms is going in the direction of developing new methods and forms of funding and reducing the share of budgetary funds in the funding of social services. The state responsible for the reforms makes an attempt to create appropriate legal and organizational conditions for the question of institutions providing social services. 相似文献

Health2020 is a promising framework of policies provided by World Health Organization (WHO) aiming to diminish the health and well-being inequalities among the citizens of countries. European Union (EU) and its member-states participate to this ambitious framework. The deterioration of major demographic, social and environmental factors, in addition to the escalation of the economic crisis prevent the successful and, without restrictions, implementation of this framework. Under such conditions, there is a strong need for all the EU member-states to utilize their health and economical resources efficiently and wisely. In order to provide a unified and value-based approach of the Heath2020 framework, we take advantage of the Data Envelopment Analysis (DEA) and Dynamic DEA methods to evaluate the impact of the Health2020 policies. This approach pinpoints the countries that can be characterized as outperformers and the lagged ones. We adopt several versions of evaluation, in relation to the regional targets of Health2020, measuring both the effectiveness and the efficiency of EU countries from 2011 to 2016. We, also, examine the stability of the technological frontier of the countries using dynamic DEA. Our results showed the existence of major dividend lines between the outperformers and the other countries. The results also reveal a stability in technological changes indicating, probably, the slow development in this sector at the field of Health. 相似文献

This article presents estimates of the impact of home safety and accessibility features on the prevention of serious, non-fatal falls for elderly widowed individuals. As these features are not randomly assigned across homes, we develop an instrumental variable (IV) strategy that relies on the differential decline in the health and functional status of spouses to identify impacts. Specifically, we use the deceased spouse’s functional status when alive, as measured by limits to Activities of Daily Living (ADLs), as an IV for the presence of home safety and accessibility features for the surviving spouse in the years after widowhood, and then estimate the effect of these features on the likelihood of a serious fall for the widow using rich longitudinal data from the Health and Retirement Study. The presence of such features reduces the likelihood of a fall requiring medical treatment by 20 percentage points, a substantial effect. However, falls are not the type of health shock that is a main driver of housing tenure transitions among the elderly. Although somewhat speculative, cost–benefit estimates suggest that investments in home safety for the elderly may generate in the short run as much as a dollar-for-dollar reduction in medical expenditures. 相似文献

This article outlines and critiques the main fiscal and economic rationales for the Private Finance Initiative and examines the impact of the policy on the long-term financial viability of NHS trusts. It concludes that the PFI funding of capital investment is highly problematic. Its high costs can have a negative impact on the finances of health systems. 相似文献

Insurers, health plans, and individual physicians in the United States are facing increasing pressures to reduce costs while maintaining quality. In this study, motivated by our work with a large managed care organization, we use readily available data from its claims database with data envelopment analysis (DEA) to examine physician practices within this organization. Currently the organization evaluates primary care physicians using a profile of 16 disparate ratios involving cost, utilization, and quality. We employed these same factors along with indicators of severity to develop a single, comprehensive measure of physician efficiency through DEA. DEA enabled us to identify a reference set of “best practice” physicians tailored to each inefficient physician. This paper presents a discussion of the selection of model inputs and outputs, the development of the DEA model using a “stepwise” approach, and a sensitivity analysis using superefficiency scores. The stepwise and superefficiency analyses required little extra computation and yielded useful insights into the reasons as to why certain physicians were found to be efficient. This paper demonstrates that DEA has advantages for physician profiling and usefully augments the current ratio-based reports. 相似文献
