建设美丽中国、实现中华民族永续发展、建设具有中国特色社会主义,必须抓好生态文明建设。习近平生态文明建设思想以马克思辩证唯物主义原理和我国传统的儒家、道家文化根基中的生存智慧作为哲学依据,是顺应时代要求的新论断。这个思想有着生态自然观与生态经济观相统一、规律性与目的性相统一、继承性与创新性相统一、科学性与实践性相统一的思想特点。有此思想指导,我国全面建成小康社会、夺取新时代中国特色社会主义的伟大胜利、实现中华民族伟大复兴的中国梦必然指日可待。 相似文献

文章基于108个城市2004-2014年市级面板数据测度了长江经济带城市生态效率的时空演变格局,综合而言,长江经济带生态效率水平呈现出波动上升态势,长江流域城市生态效率分化特征明显,湖南、湖北和四川等长江上游城市生态效率较高,长江上、中、下游地区城市生态效率依次递减.对生态效率的影响因素研究表明,科技创新显著地提高了长江经济带的生态效率,经济快速增长降低了城市生态效率,意味着转变经济增长方式、加快科技创新是提高城市生态效率的有效途径.研究还发现,产业结构偏离度有利于提高城市生态效率,而产业升级抑制了城市生态效率的增长,意味着产业升级并不是提高城市生态效率的捷径. 相似文献

西方环境主义认为人类在地球上的频繁活动将导致地球整个生态系统的破坏,要想解决环境问题就必须限制人类活动,缩小经济发展规模,避免人口过剩;而生态学马克思主义则指出,生态危机产生的根源是由于资本主义私有制的存在,环境污染和人口过剩是资本主义剥削自然和剥削人类的结果,只有建立生态社会主义社会,绿色环境主义者和马克思主义者的可持续发展理想才能实现。 相似文献

Introduction and spread of the parasite Myxobolus cerebralis, the causative agent of whirling disease, has contributed to the collapse of wild trout populations throughout the intermountain west. Of concern is the risk the disease may have on conservation and recovery of native cutthroat trout. We employed a Bayesian belief network to assess probability of whirling disease in Colorado River and Rio Grande cutthroat trout (Oncorhynchus clarkii pleuriticus and Oncorhynchus clarkii virginalis, respectively) within their current ranges in the southwest United States. Available habitat (as defined by gradient and elevation) for intermediate oligochaete worm host, Tubifex tubifex, exerted the greatest influence on the likelihood of infection, yet prevalence of stream barriers also affected the risk outcome. Management areas that had the highest likelihood of infected Colorado River cutthroat trout were in the eastern portion of their range, although the probability of infection was highest for populations in the southern, San Juan subbasin. Rio Grande cutthroat trout had a relatively low likelihood of infection, with populations in the southernmost Pecos management area predicted to be at greatest risk. The Bayesian risk assessment model predicted the likelihood of whirling disease infection from its principal transmission vector, fish movement, and suggested that barriers may be effective in reducing risk of exposure to native trout populations. Data gaps, especially with regard to location of spawning, highlighted the importance in developing monitoring plans that support future risk assessments and adaptive management for subspecies of cutthroat trout. 相似文献

The components of a reliability system subjected to a common random environment usually have dependent lifetimes. This paper studies the stochastic properties of such a system with lifetimes of the components following multivariate frailty models and multivariate mixed proportional reversed hazard rate (PRHR) models, respectively. Through doing stochastic comparison, we devote to throwing a new light on how the random environment affects the number of working components of a reliability system and on assessing the performance of a k-out-of-n system. 相似文献

ABSTRACTIn ecological studies, individual inference is made based on results from ecological models. Interpretation of the results requires caution since ecological analysis on group level may not hold in the individual level within the groups, leading to ecological fallacy. Using an ecological regression example for analyzing voting behaviors, we highlight that the explicit use of individual-level models is crucial in understanding the results of ecological studies. In particular, we clarify three relevant statistical issues for each individual-level models: assessment of the uncertainty of parameter estimates obtained from a wrong model, the use of shrinkage estimation method for simultaneous estimation of many parameters, and the necessity of sensitivity analysis rather than adhering to one seemingly most compelling assumption. 相似文献

In this article, we lament the effects of practice-distant research and associated policy initiatives on contemporary children's services in England. In the last decade, as a result of high profile inquiries into non-accidental child deaths, statutory children's social care services in the UK have been subject to a wide-reaching ‘modernization’ programme. We studied decision-making in the high blame environment of local authority children's services. Our research sought to examine the relationship between performance management and the impact of anticipated blame within the decision-making practices of those providing, supervising and managing these services. We show that systems and technologies can be developed which both assist the users in their daily work and achieve desired organizational goals, but without an ethnographically informed, practice-near approach, unsafe work regimes and practices can ensue. 相似文献
