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.

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.     

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.     

解决经济发展与淡水资源紧缺矛盾的新途径研究--以青岛市黄岛区为例

随着黄岛区迅速成为青岛市新的经济重心,该区淡水资源的紧缺与经济发展的矛盾日益突出.解决该地区水资源紧缺问题除传统的通过挖潜当地水资源及外部调水途径外,加大对海水的利用及对中水利用也是解决该区水资源紧缺问题的重要途径.结合黄岛区分区规划对黄岛区在海水利用及中水回用方面的必要性和可行性进行了探讨.     

骆马湖水体氮污染特征分析

2005年通过对骆马湖水质监测，并结合近几年的监测资料进行了分析，结果表明，氮是骆马湖水体的主要污染物，包括总氮、氨氮和硝酸盐氮，其主要特征是入湖河流、降水、围网养殖和点源带来的污染。     

含有机物铁泥的超临界水氧化法资源化

氨基染料生产过程中产生大量含有机物的铁泥,对环境造成严重污染并造成资源的极大浪费.利用超临界水氧化法对含有机物铁泥进行资源化处理研究,并对产物进行了X射线衍射分析(XRD)、色差实验与电子探针分析.研究结果显示,用超临界水氧化法处理铁泥可以将铁泥中所含的有机物完全氧化,真正实现环境友好;超临界水首先将铁泥氧化成α-Fe2O3与γ-Fe2O3,再经过800℃煅烧后可以作为氧化铁红颜料使用;超临界反应压力对样品的晶型与颜色影响不大.
