建设生态文明一直是我国的重要目标,但当前我们面临的生态问题很多,其中碳排放过量就是一个重要方面。为此,在发展低碳经济、推行低碳生产的同时,控制社区碳排放量、建设低碳社区成为我们的任务。它对于建设生态文明、促进人与自然和谐相处具有非常积极的意义。政府对低碳社区建设非常重视,也取得了显著成效,但当前依然存在诸如社区废弃物的低碳处理还处于粗放状态、居民的低碳环保意识有待提高等问题。为此,我们既需要认真总结和借鉴西方发达国家低碳社区的成功经验,又需要根据我们自己的情况进行改进,比如在社区建设低碳节能型建筑、激发社区居民在低碳环保方面的生活自觉,以及在能源的使用上尝试以新换旧等。 相似文献

城市功能拓展区既缺少核心区集聚的文化资源优势,又缺少郊区低廉的发展成本优势,但在着力发展文化创意产业的过程中,却可以通过整合文化产业园区资源,形成独特的发展优势.本文运用商业生态学理论,分析城市功能拓展区内文化产业园区发展的“三元”联动主体,构建园区资源整合的双重主体理论,并提出文化产业园区确定主导产业并吸引核心企业以“聚核”、拓展纵向产业链和横向服务链以“聚链”、打造公共平台并进行功能体系建设以“聚网”的“三聚”持续发展路径. 相似文献

This paper presents a comparative case study of academic group leaders, active in three different scientific fields at a leading Swiss technical university. It examines the obstacles that prevent scientists from commercializing their technologies and how they can be reduced. Traditional models of technology transfer assume that scientists prefer either to 'go it alone' and become entrepreneurs (the inventor entrepreneur model) or to let go of their technologies to people interested in their commercialization (the surrogate entrepreneur model). The results of qualitative research suggest that these two models capture the extremes of a continuum populated by a variety of intermediate situations where scientists are unwilling completely to let go of their findings, but also do not want to become full time entrepreneurs. This results in considerable commercial potential that is unexploited. The Founding Angels approach might be a solution to this problem; it is designed for academics in these intermediate situations. The study contributes to the literature on university-industry technology transfer and should be useful for practitioners and scientists interested in maximizing the synergies between academia and industry. 相似文献

Beginning in the early 1990’s, grazing lands once held in common were contracted to individual households in the rangeland regions of China. The resulting fragmentation of rangelands has led to ecological and social problems. As China seeks to address intractable poverty and rangeland degradation, attention has turned to rental, or transfer, of contracted grazing land as a market-based approach to re-aggregating grazing land into larger units that support economies of scale. However, given that many pastoral regions still maintain community customary institutions, what the relationship between market mechanisms and local customary institutions should be in rangeland management needs further analysis. This paper applies comparative case studies of two types of relationships between market mechanisms and customary institutions: (1) market mechanisms that replace customary institutions in the case of Axi village, and (2) market mechanisms that are embedded within customary institutions in Xiareer village. This allows contrast of the impacts of differing approaches on livelihoods, livestock production, and wealth differentiation among pastoral households. We found that there is a higher level of livestock mortality, lower livestock productivity, and higher livestock production cost in Axi Village compared to Xiareer Village. In addition, household asset levels are higher and there is less income differentiation in Xiareer Village. It is concluded that embedding market mechanisms within customary institutions has had notable benefits for the herders of Xiareer Village, because it is a better fit to the coupled pastoral social-ecological system. Based on these findings, we argue that in pastoral communities where the rangeland transfer system for contracted grazing land has not yet been implemented, it is critical to reconsider China’s current policy approach to pay greater attention to the innovative management systems being developed in local regions. Instead of considering market-based approaches as oppositional to traditional institutions, options that derive from the interaction of market-based and customary institutions should be considered. 相似文献

In the search for solutions to complex real-world problems, the benefits of transdisciplinary research (TDR) have been widely heralded. Land use science appears to be a designated field for TDR. However, to date, the additional expenses of TDR are accompanied by a so far not proved added value, and empirical findings are claimed to be scarce and dispersed over several disciplines and case studies.We reviewed 299 articles obtained from a structured literature search to (1) investigate the current differences between theory and practice, (2) identify empirical findings, and (3) ascertain the contributions of TDR to promoting sustainable land use management.Our results demonstrate that, in spite of an increasing conceptual consistency in the theoretical discussion of TDR, the implementation of TDR remains a substantial challenge, in part because of the gap between theory and practice. In addition, research on TDR is science and process centred. The benefits of TDR in addressing real-world problems within the field of land use remain unproven. 相似文献

为了避免倒车过程中因视觉盲区可能出现的安全隐患问题[1][2],文章采用飞思卡尔单片机做主机,Aptina图像传感器ASX340[3]做从机,利用ASX340内部的OVERLAY位图叠加系统,设计了一种能够将倒车过程中实时的车辆尾部的影像,距离障碍物的安全距离,倒车轨迹路径等信息提供驾驶员倒车影像系统[9][10]。使用HYRes3_1、Imatest软件[4]测量了影像图像质量的主要因素。测量结果表明成像质量能够满足目前车厂的要求。 相似文献

党的十八届三中全会以来,青海省全面实施深化改革工作,地方社会信用体系建设步伐显著加快。但是,还需通过自上而下的统一部署和强有力的制度约束,来解决信用基础薄弱、共享平台缺失、建设合力不足和以点带面机制不健全等问题。提出建立“总体要求———任务分解———基础工作———专项示范———支撑体系”这样一种全面的制度安排,以此为深化青海省社会信用体系建设提供新的思路。 相似文献

Dijkstra算法是求解最短路径问题的经典算法。在现如今的城市交通网络中,经常需要寻求两个地点之间的最短距离,减少运输时间。本文将Dijkstra算法与C语言相结合,对Dijkstra算法进行改进,根据实际网络图的情况,建立了相应的数学模型,运用C语言编程,在给定的网络图中,实现了只需确定起始点和终点,就可以直接输出最短路径和最短距离的功能。在有多个相同最短路径的情况下,会将多个最短路径一起输出,在搜索到终点时,立即跳出,结束循环。在一般情况下,无需对所有点进行迭代,提高了效率。这种方法可以应用到现在的物流运输中,以此来节约时间,降低成本。 相似文献
