东北地区农业现代化与新型城镇化协调发展研究

新型城镇化与农业现代化作为"三化"、"四化"乃至"五化"战略的重要核心内容,研究新型城镇化与农业现代化的协调发展对于开创中国未来城乡经济社会发展一体化的新格局至关重要。以东北三省34个地级城市为研究对象,构建农业现代化与新型城镇化的评价指标体系,结合熵值赋权、变异系数赋权的综合确权法测算城市农业现代化与新型城镇化的发展水平,基于耦合协调度模型探讨二者的耦合度与协调发展度,并划分其阶段类型,研究表明:(1)东北三省新型城镇化的发展水平排序:辽宁省吉林省黑龙江省,农业现代化的发展优势排序:黑龙江省辽宁省吉林省;辽宁与吉林省的新型城镇化发展速度超前于农业现代化,仅黑龙江省的新型城镇化发展滞后于农业现代化;(2)东北三省新型城镇化的高值区分布在以哈尔滨为核心的黑龙江省西南、以长春为核心的吉林省中部、以沈阳和大连为核心的辽宁省中部及南端,农业现代化的高值区分布在哈—大—齐—绥沿线的松嫩平原;沈阳、大连、哈尔滨、长春新型城镇化水平居于东北三省前列,哈尔滨、沈阳、齐齐哈尔、绥化农业现代化水平位于首位;(3)辽宁省新型城镇化与农业现代化的耦合协调发展度均强于黑龙江省,吉林省略低;耦合度高值区位于黑龙江省东北部的三江平原、辽宁省的沿海经济带,协调发展度高值区位于黑龙江省西南部的松嫩平原及以长春、沈阳、大连为核心的小范围圈层区域;仅哈尔滨与沈阳市处于勉强协调阶段,多数城市处于高强度、中高强度拮抗耦合与轻度、中度失调阶段。     

Communicating risk for vulnerable groups: a case study of the Mano community’s strategies for collective knowledge to action

This paper discusses the emergent interest in risk communication as a strategy for disaster risk reduction. Communication plays an essential role in understanding risk, but studies suggest that people often do not respond in the way that risk experts anticipate. For risk communication to be effective, vulnerable communities need to understand risk within the local context as well as in terms of sustainability. Risk messages offer communities a way to enhance their collective knowledge of existing vulnerabilities, leading them towards alternative solutions for action. A longitudinal study of the Mano community development approach and its recovery from the 1995 Kobe earthquake illustrates how risk communication dynamics contributed to the community’s sustainable risk reduction. The study concludes that risk communication is a collaborative way for a community to work with risk experts, own their risk information, influence existing policies and practices, develop solutions to reduce vulnerability, and ultimately enhance a community’s capacity for managing future risk.     

Comparison of the daily global solar radiation from different data sources in Northwest China climate

The solar radiation data are of high importance to the solar energy systems. Conventional methods to obtain the solar radiation data are from weather stations, solar radiation models, commercial software databases, and field measurements. In the present study, a new daily global solar radiation model is proposed, by combining the quadratic function of sunshine fraction and sine function of the day of the year. The solar radiation model calculated data are then compared with China Meteorological Data Sharing System (CMDSS) data, TRNSYS data, and field-measured data in Northwest China climate. It is found that the newly proposed solar radiation model has better performance than the other nine solar radiation models in the literature. The solar radiation model calculated data fit well with the CMDSS annually average data. The TRNSYS data are a bit larger than the CMDSS annually average data in summer half year and a little smaller than those in winter half year. The solar radiation model and the CMDSS annually average data have the best correlation, whereas the TRNSYS data and the field-measured data have the worst correlation. The solar radiation model calculated data have the best correlation with the other three data sources.     

Green and compatible industrial development in Western China

Western China has lagged a lot in terms of industrial structure and economic development,compared with the national average.And China announced its target of CO_2 emission reduction,i.e.by 2020,CO_2 emission per GDP will drop by40-45%compared with 2005.The target will be incorporated into China's long-term industrial planning.Against this background,this paper will make a comprehensive examination of the industrial development of Western China,aiming to discover a green and compatible way.First,we analyze the spatiotemporal evolution of regional industrial structure for the period 2000-2010.Second,we try to discover the industrial structure optimization path for Western China by employing the Vector Auto Regression model.Lastly,we try to provide some advice and suggestions for further industrial development in Western China.Our examination shows that further industrial development in Western China should pay full attention to resource conservation and recycling,and develop on a green and compatible path.     

全球低碳发展评估及中国低碳发展的实现路径

低碳发展日益成为国际关注的热点问题,中国正处在快速工业化和城镇化进程当中,通过低碳发展实现经济社会转型尤为迫切。在全球大背景下正确判断中国的低碳发展水平,汲取各国有益的低碳发展经验,寻求适合中国的低碳发展路径尤为重要。从低碳发展特征指标变动出发,通过统计分析,得出全球低碳发展历史和现状水平,以及中国所处的位置。研究表明,近20年来全球碳生产力水平不断提高,近年来中国的碳生产力水平飞速提升,但是中国的碳生产力仍然远远低于全球平均水平,离先进国家的差距更大,不足法国的1/10,人均二氧化碳排放增速位居世界前列,减排压力巨大。因此,结合国内外实践经验,总结了中国低碳发展的5个实现路径,分别是调整能源结构、发展低碳产业、倡导低碳消费、建设低碳城市和加强碳汇建设。     

房地产开发地铁振动达标距离研究

已建和待建的多条地铁线路穿过某房地产开发地块,为了防治地铁运行对建筑造成振动环境影响,需要设定建筑靠近地铁的最小达标距离,包括采取减振措施后的距离。通过现场系统实验监测结合数值模型分析,从工程实践的角度提出了上述距离。对于实验中观察到随距离出现振动局部放大以及进口与国产仪器监测结果不同的现象,佐证了有关学者的理论与实验分析,提出:(1)现有地铁环境影响评价报告常用的60m评价范围偏小,推荐可扩大至80~100m;(2)迫切需要新的振动环境标准发布,避免有关项目的环境管理要求偏低。

Consistent assessments of pathways toward sustainable development and climate stabilization

Many of the numerous difficult issues facing the world today involve relationships entailing trade‐offs and synergies. This study quantitatively assesses some alternative scenarios using integrated assessment models, and provides several indicators relating to sustainable development and climate change, such as indicators of income (per capita GDP), poverty, water stress, food access, sustainable energy use, energy security, and ocean acidification, with high consistencies among the indicators within a scenario. According to the analyses, economic growth helps improve many of the indicators for sustainable development. On the other hand, climate change will induce some severe impacts such as ocean acidification under a non‐climate intervention scenario (baseline scenario). Deep emission reductions, such as to 2°C above the pre‐industrial level, could cause some sustainable development indicators to worsen. There are complex trade‐offs between climate change mitigation levels and several sustainable development indicators. A delicately balanced approach to economic growth will be necessary for sustainable development and responses to climate change.
