生态规划在资源型城市转型实践中的作用——以抚顺市为例

目前我国一些资源型城市由于长期开采,资源已近枯竭,即将陷入可持续发展危机,如何实现资源型城市转型成为我国城市发展中十分重要的课题。为了研究生态规划对于资源型城市转型的推动作用,本文以典型资源型城市抚顺市为例,通过分析其城市生态规划的内容及近年的规划举措,得出了城市生态规划是推进城市转型的有效途径这一结论,并分析了该结论的广泛意义。     

环境统计在环境保护中的应用

环境统计是用数字反映并计量人类活动引起的环境变化和环境变化对人类影响的工作。从统计工作实践出发,通过能源环境统计数据、环境质量统计数据和污染源排放统计数据在日常环境管理中的应用实例,总结出环境统计在环境保护中的应用价值,以期引起对环境统计工作的重视。     

县域土地利用规划生态环境影响评价研究——以陇县为例

以生态服务价值理论为指导,从土地利用变化动态度、生态系统服务总价值和生态价值敏感度3个方面评价陇县土地利用总体规划(2006～2020年)对区域生态环境的影响。结果表明,林地、耕地在规划期内生态系统服务价值都呈增长趋势,区域生态系统服务总价值增加了30700万元。     

金属矿山废弃地类型划分与生态退化特征

由于矿山开采中地表结构扰动、环境污染等因素导致矿山废弃地生态系统极度退化。通过对其产生原因和占地现状、特征的分析,将金属矿山废弃地划分为5大类15个类型,对其生态退化特征进行了评价;其中地表结构的不稳定性、土壤和植被的缺失及重金属离子污染是生态退化的主要限制性特征,也是生态恢复的难点和重点,并对不同类型金属矿山废弃地的生态治理措施进行了探讨。     

鄱阳湖生态经济区经济与环境的协调性研究

对经济与环境协调性关系的分析是可持续发展的研究核心。文章根据鄱阳湖生态经济区经济和环境的发展状况,选取了7个经济指标和7个环境指标,采用主成分分析法及协调性发展指数评价方法,对2006-2010年鄱阳湖生态经济区的经济系统与环境系统的协调性进行了定量分析,通过研究提出需要进一步加大鄱阳湖生态经济区环境保护力度、加快发展循环经济和构建环境友好型产业体系等政策建议。     

快速城市化地区人工湿地景观生态功能优化研究

以太湖武进港河口人工湿地为例,在兼顾生态与景观美学的前提下,研究城乡交错区域湿地景观功能的优化设计,包括:岸边水体生态修复区,动植物景观配置,植物种类的多样性及植物种植的后处理,构建水、植物和动物三位一体的景观;形态设计,平面形态及纵断面的形态设计应实现优化人体视觉感官效果,避免简单的圆形、矩形等过于规整的形式;附属设施建设,运用跌水、花坛、小径、木亭、花架、植物等多种元素搭配,弱化硬质线条。通过上述相关的景观优化设计,达到人工湿地生态功能与景观效果的有机统一,提升人居环境质量。     

Designing the sustainable product-service integration: a product-service blueprint approach

As a means for providing the sustainable production and consumption, the concept of product-service system (PSS) has received increasing attention. What is at the core in the PSS is the design, since it determines the distinctive characteristics and quality of PSS. Even though some tools have been suggested for PSS design, previous tools mainly focus on identifying the relationship between actors in a conceptual level. Despite the fact that it is significant and cannot be neglected, what is more important in a practical situation is to represent the detailed flow or relationship of PSS elements, with the consideration of products and services. In response, this paper proposes a ‘‘product-service blueprint’ which is a new and systematic way to elucidate the relationship between products and services, providing the implication of how PSS can provide the sustainable production and consumption. Employing the service blueprint as a starting point, new areas, lines, and symbols are introduced to represent the distinctive features of PSS. The proposed product-service blueprint represents the product use throughout the life cycle, service flow from the management to the customer, and the relationship between products and services. Taken together, the product-service blueprint will help both managers and researchers to promote the product-service integration under the concrete framework.     

The water supply footprint (WSF): a strategic planning tool for sustainable regional and local water supplies

This paper introduces a new methodological approach of the ecological footprint explicitly addressing the sustainability of water supplies, which we call the water supply footprint (WSF). The WSF calculates the catchment area or water supply hinterland of a certain society and can serve as a strategic planning tool for local or regional water supplies linking the water demand with the water supply in a water supply footprint matrix. Based on regional water balances it estimates how much water can be appropriated for human use in an environmentally sustainable way.The proposed method is tested on the South East Queensland water supply in Australia, an area where water use restrictions are regularly imposed on the population. Applying the proposed method indicates that supply shortages may be avoided by considerably changing the organisation of water supply, thereby reducing and possibly even avoiding the necessity for large-scale supply side measures like additional sweet water reservoirs or desalination plants. In that way it is demonstrated that the WSF method is applicable at an early and strategic stage of water supply planning.     

基于Landsat TM遥感数据的沈阳市生态环境监测与评价

以近年Landsat TM 遥感图像为基础数据源,利用遥感与GIS技术对沈阳市生态环境状况进行了监测.结果表明,2009年间沈阳市生态环境质量处于一般水平,与2008年相比,生态环境质量指数上升,生态环境状况呈现变好的趋势.     

以生态足迹法分析评估抚顺市可持续发展

在介绍生态足迹理论和计算模型的基础上,对抚顺市2007年的可持续发展状态进行了实例计算和分析,结果表明抚顺2007年的生态赤字为4.986 3hm2,其城市处于非可持续发展的状态.在此基础上,提出了促进抚顺可持续发展的建议.
