STRATEGIC ENVIRONMENTAL ASSESSMENT FOR SUSTAINABLE DEVELOPMENT IN URBANIZATION PROCESS IN CHINA

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.

Criteria for Aggregating Sustainable Development Indicators as a Way of Modeling Through “Live and Work” City Index

Measuring and comparing sustainable development levels of cities,regions,and projects are an essential procedure in creating and maintaining sustainable urban futures.Introducing a new urban sustainable development assessment model:The Live and Work(LaW)City Model.As an indicator-based sustainable development indexing model,it aims to assist planners and policy makers in their decisionmaking procedures and development of cities by providing an integrated assessment framework.Several efforts were done to develop composite indicators,but it was concluded that most of them focused on environmental dimensions and neglected the overlapping of the other influential ones.The paper gives an overview of the nature and importance of composite indicators and how it can be structured and implemented precisely;overcoming its drawbacks,to gauge and rank the performance of cities across the demands of people,planet,and profit,as a way of achieving the LaW balance criteria.The methodology of the model is developed by following a set of logical steps such as weighing,normalization,and aggregation of individual indicators.From here,a functional form for aggregation was derived to compute the index.Furthermore,the structure of the model was illustrated in the form of a pie/radar chart.The visualized LaW city index has the communicative advantage of being easy to convey comparative levels of different values.The total values computed could be used to rank cities in a tabular format and gauge their comparable sustainable development performance accordingly.The model can also estimate the sustainable development outcomes of alternative development scenarios during different year’s intervals.This can be achieved by stacking up different model scenarios;making it a relatively simple exercise for both the general public and decision makers to comprehend.

Substitutability of urban sustainability assessment indicators:A semantic similarity analysis

Urban sustainability assessment is an effective method for objectively presenting the current state of sustainable urban development and diagnosing sustainability-related issues.As the global community intensifies its efforts to implement the sustainable development goals(SDGs),the demand for assessing progress in urban sustainable development has increased.This has led to the emergence of numerous indicator systems with varying scales and themes published by different entities.Cities participating in these evaluations often encounter difficulties in matching indicators or the absence of certain indicators.In this context,urban decision makers and planners urgently need to identify substitute indicators that can express the semantic meaning of the original indicators and consider the availability of indicators for participating cities.Hence,this study explores the relationships of substitution between indicators and constructs a collection of substitute indicators to serve as a reference for sustainable urban development assessment.Specifically,building on a review of international and Chinese indicators related to urban sustainability assessment,this study employs natural semantic analysis methods based on the Word2Vec model and cosine similarity algorithm to calculate the similarity between indicators related to sustainable urban development.The results show that the Skip-gram algorithm with a word vector dimensionality of 600 has the best performance in terms of calculating the similarity between sustainable urban development assessment indicators.The findings provide valuable insights into selecting substitute indicators for future sustainable urban development assessment,particularly in China.

Sustainability Index： An Application into Sustainable Engineering Infrastructure Management and Assessment

A proper infrastructure assessment in the contemporary engineering world has become very crucial due to the palpable resources challenges. Therefore, from the design, construction, operation and maintenance stages of the built infrastructural systems; cognizance must be taken of the associated factors and their significance. In considering these indices, the experts will save lots of resources wastage thereby integrating new technologies into the full life cycle of the infrastructure. In this paper, two sets of building infrastructure professionals were assessed. These are the corporate building organization （CBO） and the Operators from two shopping malls within the UK. Thirty-four factors regarding the sustainable building infrastructure appraisal were identified through literature reviews. These characteristics were accordingly classified into two factors （group I and II） and a comparative analysis of their influence conducted. Priority rating of the factors assessment on building infrastructure was through structured, administered survey amongst professionals within these organizations. Information of this survey revealed that the experts maintained a strong concordance in rating these factors. As a result, the associated factors have relatively substantial degree of influence in this context. Further indications of the result in groups I and II are that the CBO experts have indicated the infrastructure size, planning and design as the key factors. Also, the type of building characteristic was among others as the top and bottom marked cases. Similarly, the Operators too have maintained that a proper infrastructure design should incorporate a good policy framework for efficient energy saving fixtures and conservation. Additionally, the installation of quality equipment promotes cost savings of the resources and a just-in-time maintenance of the infrastructure at large. The maintain as-we-go philosophy characteristic was not strongly encouraged in this case.

为了城市交通的可持续发展,对城市交通承载力的可靠性进行评估和情景预测。重新定义了城市交通承载力,构建基于系统动力学的计算模型。以兰州市为例,对2023-2030年的未来交通在5种情景发展模式下的交通承载力进行可靠性评估和预测。结果表明:系统动力学模型具有较高的精度水平,绝对误差在3%以内。兰州市在5种设定情景下,2030年资源承载力均处于临界可靠状态;环境承载力在环境改善型时达到最高30.88,为基本可靠;社会经济承载力在综合发展时达到最大24.8,为临界可靠。分别提升交通资源和社会经济都会提升相应的子系统承载力,然而交通环境承载力却具有一定的下降趋势,这符合城市交通实际情况,验证了系统之间存在着复杂的正负反馈关系。城市交通承载力呈现出逐步提升的趋势,将在2026年以后均达到20以上,处于临界可靠区间。且综合发展型提升效果最好,2030年相比2022年增长47.2%,已接近基本可靠区间。

生物多样性保护成效评估指标体系和评价方法研究进展

生物多样性保护是实现生态系统可持续发展的前提,生物多样性保护成效评估是生物多样性监管的基础,科学、有效的评估能够明显提升生物多样性保护与管理水平,并显著改善区域生态环境。总体来看,现有的保护成效评估主要围绕自然保护地、生态环境和生物多样性等研究对象的状态和变化两个层面开展,评估指标体系的侧重点逐渐由管理成效向保护成效转变,评估方法基本涵盖了全球、地区、国家和单个自然保护地等多种空间尺度。然而,由于缺乏统一的指标体系和评价方法,导致区域间的评估结果难以比较,因此多尺度集成评估也难以开展。近年来,全国生物多样性监测网络和数据库的建立,以及多种新技术(如遥感、环境基因组学等)在生物多样性监测中的应用,使得宏观生态系统和微观基因水平的多层次连续监测成为可能。基于此,建议未来我国生物多样性保护成效评估应在认真总结全球生物多样性保护成效评估理论和方法的基础上,加强全国生物多样性监测网络的建设,发展适合中国区域特点的跨学科的综合保护成效评估指标体系。定期的生物多样性保护成效评估,有助于全面了解我国生物多样性保护现状及发展趋势,进而为生物多样性保护和管理决策提供支持和服务,也为中国履行生物多样性公约、实现联合国可持续发展目标提供数据和技术支持。
