论信息产业与可持续发展

信息产业与可持续发展在共同的时代背景下应运而生,相互作用又有机统一.信息产业对可持续发展有显著的正效应,主要表现为:信息产业对经济发展的贡献;信息技术的发展应用,可以减少人物流动,提高资源配置效率;合理利用自然资源,实时监测环境变化;可以通过非物质化降低能耗和物耗,等等.同时,信息产业因其固有的特殊性,又表现出与可持续发展不协调的方面,如信息安全与信息污染、电子产品中有毒元素的应用、电磁辐射及对人体的影响等.文章最后提出,信息产业对社会经济的可持续发展具有重要的推动作用,大力发展信息产业是我国产业结构调整的必然选择,以可持续发展战略指导信息产业健康发展,并以信息产业推动其他行业的可持续发展,提高资源环境利用和管理水平,是可持续发展的必由之路.     

基于博弈论的非点源污染控制模型探讨

随着对工业和城市生活污水等点源污染治理能力的不断增强,农业非点源污染对水质环境的影响日益凸现.相对于点源污染,非点源污染发生的不确定时间、不确定途径、不确定量等特点给治理政策的制定带来很大难度.本文从著名的公地悲剧现象出发,着力从市场博弈及政府监督博弈两个模型分析非点源污染制造者之间的博弈格局,并提出以“集体表现”的形式对非点源污染进行管理和控制.市场博弈模型中以一定的排污削减目标为前提,确定以成本最优的原则进行点源-非点源排污权交易是可行且有效率的;而政府监督博弈模型的结果显示:合理的环境补贴和惩罚机制、政府对自身声誉及公众形象的重视及维护对非点源污染治理起正向促进作用.     

人力成本管理的国内研究述评

香港典型地质遗迹资源与地质公园建设

香港素以金融、商业贸易中心闻名于世界,但香港境内所发育的曲折有致的岩石海岸、幽远宁静的海滩、巍峨多姿的群山、造型奇异的岛礁,弥足珍贵的自然生态和地质遗迹资源却鲜为人知。本文在对香港地质概况进行简单介绍的基础上,对香港地质遗迹资源进行系统分类和对比分析,指出西贡万宜水库至果洲群岛方圆近150 km2范围内发育的十分典型、极具规模的六方柱状节理构造景观是世界上同类岩石中罕见的地质现象,其分布面积大,露头完整,具有稀缺性、独特性和典型性,最后对香港国家地质公园一个公园,两个园区,八个景区的空间结构及每个园区的主要地质遗迹资源进行了系统归纳总结。香港国家地质公园的建立很好的起到了保育地质多样性的首要目标,同时很好地推动了香港的地质教育和科普发展。     

The Dual Model for Tourism Resource Productivity Improvement

For natural resource science, resource productivity studying is an important subject. But researches on tourism resource productivity are limited. The most significant influencing factor on tourism resource productivity is the potential market scale of tourist locations, and second most important influencing factor is the resource endowment. Regional urban population is significantly correlated with region tourist numbers, being the decisive factor of region potential tour market scale. In tourism development, the dual model should be adopted: on one hand to enhance tour spot attractiveness, on the other hand to cultivate the potential market by improving urbanization level and other means. In the situation of tourism development fever spreading, the dual model for improving tourism productivity helps to avoid the "Great Leap Forward" which means that too rapid tourism construction divorces from actual market demand.     

乌鲁木齐市一次冷空气过境天气对空气污染的影响分析

根据对2006年11月20～28日乌鲁木齐市出现冷空气过境天气过程的天气形式和主要气象要素及空气污染变化情况进行的分析,结果表明:冷空气过境天气前后,诸多气象要素发生了变化,冷空气导致逆温层的破坏和降水过程使各项污染物均得到有效的清除.通过此分析可为类似天气的空气质量预报提供思路.     

Making water policy work in the United Kingdom: A case study of practical approaches to strengthening complex,multi-tiered systems of water governance

We propose a suite of actions for strengthening water governance in contexts with complex, multi-tiered arrangements. In doing so, we focus on the collective water policies and approaches of the United Kingdom (UK), including those of devolved governments, which confront a host of serious water-related challenges—from massive flooding of urban areas and agricultural lands, to pressure on aquifers from rising water demand and drought. Further complexity in addressing these challenges has emerged in the wake of the June 2016 vote to leave the European Union (EU), so-called ‘Brexit’, and the ensuing ‘separation process’ with uncertainties for institutional and governance arrangements to follow. We make ten proposals for improving and reinvigorating water policy in complex, multi-layered situations, and comment specifically on their application in the UK setting. These are: put in place a system-wide water policy; fully embrace community-led nested river basin planning and management; fully fund river basin planning and management; re-focus the policy framing; use best-available data and information; create conversational spaces and become a more water-literate society; mobilise people; support and sustain core community networks; underpin river basin plans with regulatory provisions and effective monitoring and enforcement; and address systemic institutional amnesia. Individually and collectively, we contend that these actions will have a marked effect on transforming the planning and management of water resources. A system-wide water policy that maintains and builds on the substantive biophysical and socio-economic benefits delivered through implementation of the EU Water Framework Directive, together with the more recent Floods Directive, will galvanise stewardship of water in the UK. We urge more active engagement with and empowerment of the multiplicity of system ‘actors’, and highlight the role of non-government actors in a post-Brexit world as conduits for reaching out to and connecting directly with a wide range of water-related actors, especially across the EU. While attention to-date has focused on a plethora of specifically water-related projects, initiatives, plans and regulations, what is really needed is a systemic, long-term view of water resource management.

ZJR型涂料的制备及特性研究

利用溶胶凝胶法制备TiO2光催化剂,使用磷酸氢二钠、十水合四硼酸钠和氢氧化镁等制备了阻燃体系料,复合后制成ZJR涂料。利用热分析仪分析纳米TiO2和阻燃体系复合的防火涂料的温度与热失率关系,并得到热重与微商热重曲线。550~650℃之间,失重率约为11%,ZJR涂料在400~600℃有较好的阻燃效果。该涂料对污染气体的光催化降解研究结果表明:光照60 m in后,对二氧化硫的降解率为90.40%,紫外光照40 m in后,甲醛气体降解率为68.98%。进一步添加聚乙二醇和银离子使涂料改性,使涂料光催化甲醛的活性分别提高了11%和14%,效果显著。
