基于生态足迹我国三大经济圈可持续发展能力研究

本文基于当前国际上流行的生态足迹(Ecological Footprint,简称EF)模型,以可持续发展理论、区域经济学理论、生态经济理论等相关理论为基础,理论分析与实证分析、定性分析与定量分析相结合的原则,采用社会经济各相关部门的统计数据、相关研究报告的资料,针对中国东部地区三大经济圈的实际情况,建立了区域可持续发展评价指标,评价了三大经济圈的可持续发展能力,明确了当前三大经济圈社会经济发展所处的状态、存在的问题,研究结果可以为制定保证三大经济圈社会、经济实现可持续发展的政策提供科学依据和指导.研究表明,我国三大经济圈可持续发展能力较差,内部的经济与环境不协调性以及不合理的经济结构是制约三大经济圈可持续发展的主要问题.

工业综合开发区环境影响后评估探讨

环境影响后评估是提高环境影响评价有效性的重要手段。工业综合开发区环境影响不同于一般建设项目环境影响,因而后评估具有不同的特点。该文以福建省龙海角美工业综合开发区环境影响后评估试点工作为例,介绍了工业综合开发区环境影响后评估的主要内容和技术路线,阐述了对环境影响后评估的理解和体会。      

湘鄂赣农业资源与专业化区域化方向

湘鄂赣地理位置优越,农业资源丰富,稻谷、茶叶、麻类、棉花、油料、柑桔和淡水产品、禽蛋、肉类等在我国居有重要的地位,因此,大力发展三省农业生产,对我国人民实现小康生活具有战略意义。今后,要加速专业化区域化进程。我们找出生产潜力所在:改造低产田、低产园、低产水面;开发“三高”技术;开垦荒地、荒山、荒水;适当提高复种指数。通过建设,三省主要农产品将自给有余,还可满足国内外市场的需要。努力方向:高效农业开发——综合农业开发,吨粮田开发,玉米带开发,饲料稻开发,山区开发;合理布局农业生产;深化农业商品基地建设,发展综合利用,搞活商品流通;全面提高农业现代化水平,加强农业社会服务体系。     

Uncertainties in a risk management context in early phases of offshore petroleum field development

The current risk management approach for the Norwegian offshore petroleum industry came into effect in 2001 and has been stable with minor changes for 15 years. Relatively few new installations were slated for development until quite recently, and several new projects have been started in the last few years. The paper considers the risk management approach in the pre-FEED phase and builds on two case studies selected from the most recent cases. These case studies have been evaluated with respect to how uncertainties are considered in the early phase, based on the submission of the Plan for Development and Operation, their evaluations by authorities and the supporting documents. Both case studies involve new concepts for which there is no experience from similar environments and/or water depths. In spite of what could have been expected, the case studies conclude that uncertainties have not been in focus at all during concept development. This appears to be definitely the case for the licensees, but also to be the case for the authorities. Some suggestions are presented for what could have been considered by the licensees and authorities.     

Establishing the green neighbourhood: approaches to neighbourhood-scale sustainability certification in Portland,Oregon

ABSTRACT

While local governance is widely acknowledged as an important element in the pursuit of sustainability, local action alone is insufficient to produce lasting change. One recent solution to this quandary has been the production of certification frameworks that encourage sustainable development at the neighbourhood scale by providing local actors with standardised definitions of sustainable practices. While these frameworks facilitate the spread of sustainable development strategies between local communities, there are significant contrasts between their approaches to encouraging local sustainable development that simultaneously fulfils global objectives. This article explores these contrasts through two neighbourhood-scale sustainability certification frameworks: LEED for Neighborhood Development (LEED-ND) and the EcoDistricts Protocol. Analysis of these frameworks in the context of two centrally-located neighbourhoods in Portland, Oregon, reveals substantial contrasts between the two frameworks in terms of the relative flexibility of their sustainability metrics, the time frame over which decisions regarding sustainable development are made, and community involvement in the process of pursuing specific objectives. Furthermore, it suggests that greater flexibility in the application of standards, continuous governance, and greater community involvement lead to more dynamic and holistic forms of sustainability that evolve as both local community needs and broader understandings of sustainability change over time.     

战略环境评价在内蒙古“十一五”规划中的应用——以水环境为例

实施战略环境评价（SEA）,充分考虑战略的环境影响是全面落实我国可持续发展战略的前提和重要保证。内蒙古“十一五”规划SEA实现了真正意义上的战略环评。本文以水环境为例,运用情景分析法、压力分析法探讨了战略环境评价水环境压力的变化。引进容量承压度的概念,分析了内蒙古自治区经过“十一五”5年的发展重点区域水环境容量承压度的变化。计算结果表明,与2004年水环境压力相比,内蒙古“十一五”规划重点发展区域氨氮压力增大,COD压力变化较小。根据压力变化提出了水环境影响减缓措施。

区域开发建设环境污染防治措施的探讨

区域开发具有较大的不确定性,并且占地面积大、开发的内容广、性质复杂、建设周期长,通常的区域开发都有可能涉及到工业、城建、商业、人居、市政等多个领域的开发活动,所以区域开发必须结合区域开发的特征,准确识别其可能对区域内及其周边的空气环境、地下水质量、地表水水质及水文条件、声环境、土壤、植被、地形地貌等自然环境和人口、交通、经济结构等社会环境等产生的影响,并采取发展循环经济,减少污染生成的源头控制措施;科学规划产业结构,合理布局的预防性措施;源内达标、区域集中控制的污染治理措施;实施清洁生产、总量控制,推进区域环境与经济的持续发展。
