Urbanization strategic environmental assessment （SEA） is an effective instrument to enhance the harmonious development of urban complex system, integrating of environment and development in decision-making. Urbanization strategic environmental assessment integration technology system （SEA-ITS） is composed of ＂3S＂ （RS, GIS and GPS）, environmental expert system and environmental model system, coupling with appropriate SEA working process closely. In this paper, the structure and components of SEA-ITS are analyzed based on Chinese characteristics, meanwhile methods to fulfill the following system functions are discussed： urbanization SEA inquiring, analysis, discrimination, assessment, prediction, decision-making and output. Moreover, methods and technologies employed in different urbanization SEA hierarchies are summarized. As a case study, urbanization SEA-ITS is applied in Changchun City to solving complex real problems. Methods such as system dynamics and grey cluster are adopted to achieve the environmental impact assessment on the eco-industrial system planning. It is revealed that the system designed is capable of reflecting the dynamic behavior of eco-industrial system under different scenarios, meanwhile accomplishing strategy optimization and supplying scientific reference. The 4th strategy, namely concerning on economy increase and its interaction with science, technology and environment progress, would have the best efficiency. Further, more attention should be paid to the secondary development of integration techniques and function modification system of urbanization SEA-ITS. 相似文献

This paper reviewed the development of Strategic Environmental Assessment (SEA) in China, expounded its functions and regional characteristics, and discussed the targets of SEA in the process of urbanization,and the main assessment indicators, procedures, techniques and methodologies of SEA. It concluded that SEA could be improved by the following recommendations: incorporating SEA in decision-making process, selecting experimental units for SEA trial run, and developing strategic evaluation tools and techniques. SEA can provide appropriate and up-to-date information on the impact of human activity on environment in the process of urbanization, and develop a plan of action targeting implementation of intervention for the rehabilitation and preservation of the ecological stability of a city. Therefore, SEA can be a supporting tool for decision-making toward achieving sustainable development. 相似文献

Brownfield redevelopment is a new urban land use strategy to pursue the ideal of sustainable development. It relieves environmental pressure and resolves the glaring contradiction between urban land idleness and urban sprawl. It addresses issues of urban land use and farmland protection in China. This paper compares brownfield with greenfield, and defines brownfield and its redevelopment. It elaborates general and special government policies for this sustainable land use strategy in the context of China. General policies contain two aspects: clarifying brownfield redevelopment's priority in Chinese urban planning and land use and setting a general quantitative redevelopment target. The extent of the government's special policies, which aim at coordinating three factors in the redevelopment process, namely govern- ments, developers and users, are divided into five areas: statistics and categorization, assessment and remediation, fi- nancial supports and tax incentives, environmental and legal liability, and publicity and guidance. The paper concludes the major functions of different levels of Chinese government in the redevelopment process, i.e. making general strategy, formulating legislation, spectifying regulations and technical standards, estimating and categorizing brownfield sites, drawing up brownfield planning, providing information and financial support, guiding developers, publicizing the strategy to the public, and checking reuse results. 相似文献

The study on humanity response to global environment change is a new direction in the research of global change science, of which an important aspect is to study the adaptation strategies of human being to environ-mental changes in different regions. One reasonable and scientific adaptation strategy is based on not only scientific assessment of the impact of environmental change on society, but also correct estimation of the public perception of environmental change, whereas the research on the latter is terribly weak. This paper intends to understand the per-sonality difference in public perception of environment in the western China primarily by establishing the assessment index system of nation environmental perception and analyzing the results of questionnaire survey in some regions of Shaanxi Province. The conclusions are as follows: 1) The state of public perception of disaster is one of the founda-tions of constituting and enforcing reasonable adaptation strategy to environmental change. 2) The personality differ-ences of public perception of disaster appear as follows: female disaster perception is stronger than male.the order of disaster perception from strong to weak from the point of age characteristics is 20-30, 0-20, 40-50, 30-40, 50-60,60 year old or over in turns; the order of disaster perception from strong to weak from the point of educational char-acteristics is senior high school, college, illiterate, junior high school, primary school, in turns; the order of disaster perception from strong to weak from the point of occupation characteristics is student, farmer, teacher, worker and functionary, in turns; the order of disaster perception from strong to weak from the point of habitat characteristics is city, countryside, towns, and metrooolis in turns. 相似文献

土地覆盖信息是地理国情监测、生态环境建模等领域的重要组成。逻辑回归方法是土地覆盖变化信息局域精度量化颇有潜力的方法之一。在逻辑回归建模中,可从待检验地图提取若干像素尺度的景观指数(如像素类别、同质性、异质性、斑块大小等),用作协变量;基于验证样本,可估计逻辑回归系数,从而进行未采样点位的的精度预测。关于协变量的选择有两种策略:一是直接使用土地覆盖变化图中的若干景观指数作为协变量(直接策略),二是使用两时相的土地覆盖图中相应的景观指数的组合作为协变量(组合策略)。基于武汉部分城区的验证结果显示,两种策略下的逻辑回归预测结果的差异不明显。因此,从提高计算效率的角度,推荐采用直接策略进行土地覆盖变化信息的局域精度预测。 相似文献

The Yushu Ms 7.1 earthquake occurred on April 14,2010 in Qinghai Province,China.It induced a mass of secondary geological disasters,such as collapses,landslides,and debris flows.Risk assessment maps are important for geological disaster prevention and mitigation,and also can serve as a guide for post-earthquake reconstruction.Firstly,a hazard assessment index system of secondary geological disasters in the earthquake region was built in this paper,which was based on detailed analysis of environmental and triggering factors closely related to geological disasters in the study area.GIS technology was utilized to extract and analyze the assessment index.Hazard assessment maps of secondary geological disasters were obtained by spatial modeling and overlaying analysis.Secondly,an analysis of the vulnerability of hazard bearing bodies in the area was conducted,important information,such as, population density,percentage of arable land, industrial and agricultural outputs per unit area were regarded as assessment indices to evaluate socioeconomic vulnerability.Thirdly,the risk level of secondary geological disasters of the area was obtained by the formula:Risk=Hazard×Vulnerability. Risk assessment maps were categorized into four levels,including"low","moderate","high"and"very high".These results show that some urban areas are at very high risk,including Jiegu,Chengwen,Xiaxiula and Sahuteng towns.This research can provide some references and suggestions to improve decisionmaking support for emergency relief and post- earthquake reconstruction in the study area. 相似文献

Europe＇s mountains cover nearly half of the continent＇s area and are home to one fifth of the European population. Mountain areas are hotspots of biodiversity and agriculture has played a multifunctional role in defining and sustaining mountain biodiversity. Ongoing trends of agricultural decline are having negative impacts on mountain biodiversity. This paper presents results from an interdisciplinary European research project, BioScene, which investigated the relationship between agriculture and biodiversity in six mountain study areas across Europe to provide recommendations for reconciling biodiversity conservation with social and economic activities through an integrated rural development strategy. BioScene used scenario analysis and stakeholder participation as tools for structuring the analysis of alternative mountain futures. Three main BioScene scenarios were evaluated： Business as Usual （BAIT）, Agricultural Liberalisation （Lib）, Managed Change for Biodiversity （MCB）. BioScene brought together ecologists, economists, sociologists and rural geogra- phers, to carry out interdisciplinary analysis of the scenarios： identifying key drivers of change, assessing the biodiversity consequences and evaluating costeffectiveness. BioScene used a sustainability assessment to integrate the research outputs across natural and social science disciplines to assess the broader sustainability of the scenarios in terms of biodiversity, natural resources, rural development, social development, economic development and institutional capacity. The sustainability assessment showed that the MCB scenario was potentially the most sustainable of the three BioScene scenarios. Through the reconciliation of potentially conflicting objectives, such as conservation, economic development and human livelihoods, and with a strong participatory planning approach, the MCB scenario could represent an alternative approach to BaU for sustainable rural development in Europe＇s mountains. BioScene confirms the necessity for natural and social scientists to work together to seek solutions to environmental problems. Interdisciplinary research can assist with the definition of integrated strategies with the potential to reconcile the ecological, social and economic parameters that determine a sustainable future for European mountain areas. 相似文献
