基于双目标渐进法的中国省域生态文明发展水平评估研究 总被引:1,自引:0,他引:1
本文构建了包含4个领域、10个目标、25个指标的省域生态文明发展水平评估指标体系。在对比和改进现有数据标准化处理方法的基础上,提出双目标渐进法对评价指标进行归一化处理,并采用综合加权指数法对2014年我国的31个省、自治区、直辖市的生态文明发展水平进行评估。结果显示,我国生态文明发展水平较低,东南沿海地区生态文明发展水平高于中西部地区。总体来看,目前我国整体经济社会建设成效显著,但我国生态文明发展水平与预期目标及国际水平相比还有一定差距,因此在生态环境保护、工业污染控制、产业优化和资源高效利用方面还需加强。 相似文献

总结我国京津冀、长三角和珠三角地区不同季节基于气溶胶质谱仪的外场观测研究,探讨我国非难熔性亚微米气溶胶(NR-PM_1)化学组分和来源的时空变化特征。结果表明,3个地区NR-PM_1质量浓度变化范围为15.3~90.5μg/m~3,京津冀浓度最高,珠三角最低;3个地区中有机物均为NR-PM_1的主要组分,占24%~58%;珠三角地区硫酸盐含量更高,硝酸盐含量低;各地区秋冬季NR-PM_1质量浓度高于春夏季,主要是由于燃烧排放的一次有机物(BBOA、CCOA)与无机物(氯化物)增多造成;对有机物源解析的统计发现,机动车源(HOA)与二次源(SOA)在各地区站点中广泛存在,而烹饪源(COA)则一般存在于城市站点;生物质燃烧源(BBOA)在长三角、珠三角地区更为广泛,燃煤源(CCOA)主要存在于京津冀地区。 相似文献

深化生态文明建设的战略布局,客观上要求对我国的生态文明建设与国际进行比较,以确立赶超目标,找准发展重点。本研究构建了生态文明建设国际比较指标体系,以20国集团经济体的生态文明建设状况为评价对象,从生态状况、环境质量、社会发展和资源利用领域展开评价,获得各经济体生态文明指数2017和生态文明建设进步率(1990—2015)。量化评价结果显示,我国的生态文明建设水平排名靠后,与发达国家的最大差距在环境质量上,其次是资源利用效率。但我国在建设进步的速度上遥遥领先于其他经济体,正在奋起直追。本研究提出了提升我国生态文明建设水平的任务层次、战略重点以及赶超先进水平的时间节点。 相似文献

工业设计产业区域竞争优势比较研究 总被引:1,自引:1,他引:0
运用波特钻石模型理论确定影响设计产业竞争优势的关键因素,开发量表并设计问卷,完成珠三角和长三角设计产业竞争优势比较研究。分析显示:两地制造业和国际设计需求相对不足,设计企业经营管理和竞争策略颇为类似,政府设计促进政策实效不佳;但长三角在设计师薪酬、产业配套和发展机遇方面优于珠三角,其产业整体竞争力亦强于珠三角。 相似文献

Rapid economic integration of Hong Kong and the Pearl River Delta under the policy of “One Country Two Systems” and the consequent social and environmental degradation mean that assessment of sustainability impacts of development projects is essential. However, some fundamental problems are identified for the two systems to carry out SIA before embarking on development projects: minimal integration in terms of institutional set-up, strategies and policies concerning sustainable development; pre-set sustainability indicators rather than tailor-made ones to assess policies, programmes and projects of various nature; and rather different social, economic and environmental norms and development problems. In the short run, given these constraints, SIA in the region though “necessary” is rather “impossible”. Nevertheless, recommendations are put forward to facilitate regional cooperation of SIA practices in the longer term. 相似文献

Urban scaling laws relate socio-economic, behavioural and physical variables to the population size of cities. They allow for a new paradigm of city planning and for an understanding of urban resilience and economics. The emergence of these power-law relations is still unclear. Improving our understanding of their origin will help us to better apply them in practical applications and further research their properties. In this work, we derive the basic exponents for spatially distributed variables from fundamental fractal geometric relations in cities. Sub-linear scaling arises as the ratio of the fractal dimension of the road network and of the distribution of the population embedded in three dimensions. Super-linear scaling emerges from human interactions that are constrained by the geometry of a city. We demonstrate the validity of the framework with data from 4750 European cities. We make several testable predictions, including the relation of average height of cities and population size, and the existence of a critical density above which growth changes from horizontal densification to three-dimensional growth. 相似文献

This study meticulously explores the agglomeration mechanisms in microscale droplet aerosols, specifically focusing on acoustic and turbulent agglomeration mechanisms. Our theoretical analysis reveals a significant impact of orthokinetic and hydrodynamic processes on acoustic agglomeration. The acoustic wake effect elucidates the swift replenishment of small particles subsequent to an orthokinetic phase. An optimal frequency, varying for different droplets, was identified in orthokinetic agglomeration within the 50–250 Hz range. Hydrodynamic agglomeration remained relatively stable at an acoustic frequency exceeding 1000 Hz. The aggregation kernel function, denoted as Kij, exhibited a significant increase with increasing sound pressure levels, reaching up to 10−8 s−1. Environmental temperature had a predominantly positive effect on orthokinetic and Brownian agglomeration, although it exhibited an inhibitory effect on hydrodynamic agglomeration. For raindrops, a correlation was identified between particle spacing and Kij; a larger particle spacing corresponded to a smaller Kij. Despite an increase in particle spacing to 50 times the particle diameter, the hydrodynamic effect persisted. The aggregation kernel function linked to Brownian thermal motion was found to be 3–4 orders of magnitude lower than that of orthokinetic and hydrodynamic interactions. Additionally, the turbulent agglomeration kernel function for fog, cloud, and rain droplets with corresponding parent nuclei of 100 μm was of the same order of magnitude as the acoustic agglomeration kernel function. 相似文献
