中国能源安全的路径选择与战略框架

能源是国民经济可持续发展的基础,可持续能源战略对保障国家能源安全具有重要意义,能源安全与能源战略日益成为当前国际社会和国家安全战略中备受关注的重大问题.本文从中国的现实状况出发,阐述了制定国家能源安全战略的重要性,提出了能源安全的选择路径,构建了全面性能源安全战略框架,为制定我国长期能源安全战略提供参考.论文认为:国家能源安全战略是能源可持续供给、社会经济健康发展、突发事件合理应对、生态环境安全的重要保障;中国能源安全的路径应从能源供给安全、能源生产和使用安全、能源运输安全、能源环境安全及能源安全预警机制等方面进行选择;健全能源管理体制、能源政策、能源市场、能源技术、能源战略储备、提高输送能力、能源环境与节能是能源安全战略框架的重要内容.并提出以下建议:建立国家能源安全综合协调机构;运用市场机制提高能源效率,促进能源利用多元化;加快替代能源和新能源的技术研发;加强能源资源的战略储备.     

人的全面发展评价模型及实证分析

根据科学发展观的内涵,通过社会发展环境、生活质量及人口素质等六个评价准则构建了人的全面发展评价指标体系。在客观赋权法和主观赋权法赋权的基础上,通过相对熵优化理论对四种权重进行组合赋权的方式确定最优权重,建立了人的全面发展综合评价模型,并对中国典型的10个副省级城市进行实证分析。     

环境影响跟踪评价实践与理论研究进展

目前对跟踪评价的含义、目的、主要工作内容、实施步骤等已有了比较系统的研究,但是对战略层次跟踪评价的研究还比较少。本文首先回顾了环境影响跟踪评价在国内外的理论成果,总结跟踪评价的实践经验,认为跟踪评价主要驱动力来自于立法、决策方自身利益以及公众压力3个方面,并对今后我国开展跟踪评价工作提出相关建议,包括应加强规划环境影响跟踪评价的理论研究、建立相关的跟踪评价制度和开展跟踪评价试点等。

昌黎县大气环境污染分析与防治实践

昌黎县近几年环境空气监测数据显示:大气环境质量有所下降,环境受到轻微污染。污染产生的主要原因为冬季燃煤造成污染物排放增加及风沙、扬尘影响,结合本县采用发展集中供热、改善燃料构成、提升监管力度、严格环境管理、加大资金投入、开展末端治理等防治实践进行探讨。     

HIV and AIDS: Responding to a threat to education for sustainable development

The article seeks to sensitize the development community, particularly outside the education sector, about the issues surrounding education as a vehicle for promoting sustainable development in an AIDS environment in Africa. By illustrating how the epidemic impacts education sector staff as well as parents and students at all levels, the article intends to suggest how national authorities, NGOs and donor agencies can work out strategies to enhance the role of education in promoting sustainable development in Africa. Analysis will demonstrate how the AIDS epidemic weakens the education sector, particularly in countries with a generalized epidemic (defined as more than 3% of the adult population being HIV‐positive), undermining the sector's ability to contribute to general literacy and sustainable development. The article will demonstrate that HIV and AIDS is still not fully accepted as an educational issue, which has hampered efforts to deal with its ravages in the educational sector. The need for holistic policy frameworks for supporting teachers and administrators living with HIV and AIDS will be discussed as well as how changes in curriculum and better relations with the community are important in addressing the needs of students. The article will highlight options for developing innovative responses to HIV and AIDS in African education, showing how different forms of education can serve as vehicles for responding to the challenges of the epidemic. The examples emphasize the importance of learner‐centered instruction and partnerships with the health sector and other resources needed in an AIDS‐affected environment. Key messages of the article are that the HIV and AIDS epidemic is a multi‐sectoral problem and that responding to it effectively in the education sector requires coherent responses that address the needs of learners and instructors, including those who are personally affected or infected by HIV and AIDS. Adapting the Education for Sustainable Development initiative to address the challenges posed by the epidemic must be supported by policy development, leadership and advocacy. Diverse partnerships are essential, as the education sector alone cannot deal with the challenge of HIV and AIDS to sustainable development.
