欠发达地区县域经济可持续发展障碍与对策--以云南省凤庆县为例

通过对区位优势不明显,社会、经济和文化落后,但资源丰富的典型的欠发达县域凤庆县的实证研究,从思想观念、所有制结构、产业结构、基础建设、社会文化和经济,以及生态环境和农业基础等方面剖析了凤庆县经济不可持续发展的主要症结及原因,提出了该县经济可持续发展的总体思路,并作了对策探讨.     

贵州省湄潭县生态旅游发展规划研究

湄潭县旅游资源丰富,本文介绍了湄潭旅游资源的现状,从缺乏旅游精品、资源整合不足、文化挖掘不深、旅游宣传不力、旅游设施滞后、旅游人才匮乏等方面分析了旅游产业存在的不足,提出了发展生态旅游的思路,从茶文化、乡村休闲度假和浙大西迁文化和湄江山水四方面设计了生态旅游产品;从低碳旅游设施建设规划和体验式生态旅游规划两方面规划了绿色服务产品,并提出从旅游者、从业者和政府三个层面构建管理型生态旅游;最后对湄潭生态旅游发展提出了展望。     

生态经济学视角下的循环农业：理论、实践与发展方向

农业经历了生态农业、化学农业到生态农业的变迁,生态农业是起点也是终点。发达国家饱尝了发展化学农业的苦果,随后转轨到生态农业的道路上,最后认识到只有发展循环农业才能够做到农业可持续发展。发达国家的循环农业特别强调生态内涵和变废为宝理念,政府的财政投入和科研投入力度很大。相比之下,我国虽然已经开始发展循环农业,但目前还并不普遍,化学农业还占有很大比例。学习吸收发达国家的经验,会让我国尽早走上循环农业的发展道路。循环农业是我国农业的发展方向,为了做到这一点,需要强化农业产业化力度、加大财政补贴力度和科研投入力度。     

西方发达国家转移环境灾害的途径、原因及对策

发达国家的环境问题尤其是灾害问题的改善,在很大程度上是以将国内的致灾因素向发展中国家转移为条件的。发达国家主要通过资源掠夺资源引进、国际投资与国际贸易等途径向发展中国家转嫁各种灾害;世界经济秩序的不平等性、国际贸易与投资理论的不合理性、现行国际法规及规则的不完善性是发达国家转嫁灾害的主要成因;控制灾害的转嫁必须坚持历史责任原则和可持续发展原则两个基本原则,并采取相应对策。     

Energy efficiency and appliance’s characteristics considered prior to purchase: Differences and similarities between the United Kingdom,Germany, Portugal,Greece, Poland,Spain and Italy

This article reports country differences in the consumer’s most considered characteristics when choosing electrical appliances, including but not restricted to the energy efficiency aspect. A survey was performed to store customers from 7 countries: the United Kingdom; Germany; Portugal; Greece; Poland; Spain; Italy. Results showed consistency between countries in the top three characteristics considered: cost; quality; and a balance between price and quality. Differences were found for reported environmental attitudes and behaviours, purchase motives, and store employees evaluation. The results may support national policies and store level energy efficiency interventions. Specifically, they can provide input for store employee’s training, in persuading customers towards the purchase of energy efficient appliances.     

农村饮用水安全及其对策措施

针对农村饮用水安全总体状况及存在的问题,如工农业点面源、生活污染源造成农村水环境污染,饮用水质超标,季节性缺水、供水设施简单、制水工艺不足、供水水质二次污染,水源保护及水质监测不力、行业管理服务滞后等,强调"以人为本"的原则,正确认识农村饮用水安全内涵及卫生指标体系。采取加大工程建设方案优化力度、增强饮水工程规划设计的科学性、兴办乡村供水工程、采用合理的水处理技术设施、加强水质检测建设等工程措施,以及严防农村点与面源污染、加强农村水源地保护、创新农村饮用水安全管理制度及监督措施、完善农村饮水安全监测体系、积极研究农村饮水安全问题等措施,保障农村饮水安全。     

Assessing health impacts in complex eco-epidemiological settings in the humid tropics: Modular baseline health surveys

The quantitative assessment of health impacts has been identified as a crucial feature for realising the full potential of health impact assessment (HIA). In settings where demographic and health data are notoriously scarce, but there is a broad range of ascertainable ecological, environmental, epidemiological and socioeconomic information, a diverse toolkit of data collection strategies becomes relevant for the mainly small-area impacts of interest. We present a modular, cross-sectional baseline health survey study design, which has been developed for HIA of industrial development projects in the humid tropics. The modular nature of our toolkit allows our methodology to be readily adapted to the prevailing eco-epidemiological characteristics of a given project setting. Central to our design is a broad set of key performance indicators, covering a multiplicity of health outcomes and determinants at different levels and scales. We present experience and key findings from our modular baseline health survey methodology employed in 14 selected sentinel sites within an iron ore mining project in the Republic of Guinea. We argue that our methodology is a generic example of rapid evidence assembly in difficult-to-reach localities, where improvement of the predictive validity of the assessment and establishment of a benchmark for longitudinal monitoring of project impacts and mitigation efforts is needed.
