The enactment and implementation of the 2003 EIA Law in China institutionalised the role of plan environmental impact assessment (PEIA). While the philosophy, methodology and mechanisms of PEIA have gradually permeated through the various levels of government with a positive effect on the process and outcome of urban planning, only a few cities in China have so far carried out PEIA as a Strategic Environmental Assessment (SEA)-type procedure. One such case is the southern city of Shenzhen. During the past three decades, Shenzhen has grown from a small town to a large and booming city as China has successfully and rapidly developed its economy by adopting the “reform and open door” policy. In response to the challenges arising from the generally divergent processes of rapid urbanisation, economic transformation and environment protection, Shenzhen has incrementally adopted the SEA concept in developing the city's Master Urban Plan. As such, this paper reviews the effectiveness of PEIA in three ways:
  • • 
    as a tool and process for achieving more sustainable and strategic planning;
  • • 
    to determine the level of integration of SEA within the planning system; and,
  • • 
    its effectiveness vis-à-vis implementation.
The implementation of PEIA within Shenzhen's Master Urban Plan offers important insights into the emergence of innovative practices in undertaking PEIA as well as theoretical contributions to the field, especially in exploring the relationship between PEIA and SEA and highlighting the central role of local governing institutions in SEA development.  相似文献

从江苏省环境安全形势出发,借鉴“压力-状态-响应”(PSR)模型的框架思路,构建了环境安全度量的层次指标体系。从环境安全的压力、状态、响应3个方面确定相应的指数及对应的评估指标,通过基于德尔斐法的层次分析法确定权重,计算环境安全综合指数,并建立环境安全等级划分标准。应用建立的环境安全评估体系,对2006-2012年江苏省环境安全进行了评估。结果表明:2006-2012年,全省环境安全综合指数呈明显下降趋势,安全等级由中警状态好转为预警状态,江苏省环境安全形势不断改善。但2012年以来,大气灰霾、酸雨等复合型污染有所加重,环境安全接近中警状态,全省环境安全形势亟需进一步采取措施进行有效保障。  相似文献

对广东省空气质量等级预报准确性评估进行了探讨,结果表明,在不区分污染等级的情况下,2016年夏季广东各市的预报准确性差异较大,中山预报准确性达92%,是全省唯一一个准确性超过90%的城市,云浮最低,为53%。在区分污染等级时,实测为轻度及以上污染级别的情况下,各市的准确性普遍较低,仅佛山、东莞与广州的准确性达50%以上,而有11个城市的准确性为0。综合考虑不同污染级别的准确性得分后,佛山市排名第1,较不区分污染等级时的排名提前9名。指出,采用区分污染等级的预报效果评估办法更加适合广东空气污染较轻的区域。在首要污染物为臭氧的情况下,广东省平均的等级预报准确性低于首要污染物为其他物种的情况。  相似文献

应用基于有限体积法及黎曼近似解的二维水流泥沙模型,在无结构网格上对偏微分方程进行有限体积的积分离散,以苏州港太仓港区庵弄村岸线调整工程为例,预测采砂吹填作业产生的悬砂对长江水体的水环境影响。结果表明,采砂产生的悬砂影响范围较大,但集中在江段中间,对水厂取水口有一定影响。若采取静置等措施,可将吹填作业悬砂产生的水环境影响控制在较小的范围之内。二维泥沙模型对采砂吹填作业施工可能引起水体污染的范围和程度的预测为该类项目环境影响评价的审批提供了科学依据。  相似文献

基于2018年高分系列遥感影像数据,提取山东省省级自然保护区人类土地利用活动信息,探讨人类活动对山东省省级自然保护区的影响。结果表明,自然保护区人类活动总面积占保护区总面积的22.2%,人类活动影响指数介于0~0.01368。不同类型的自然保护区人类活动面积不同,主要影响因子差异明显,森林生态类保护区以农业用地为主,内陆湿地类保护区以养殖场为主。内陆湿地类保护区是受到人类干扰程度最为严重的保护区类型,野生动物类保护区受到人类影响最小。  相似文献

The utilisation of Social Impact Assessment (SIA) in Iran is analysed in terms of its policy context and its application in practice. Five case studies where SIA was employed in conjunction with Environmental Impact Assessments (EIA) for agricultural development projects are evaluated. In addition, the performance of the policy context is assessed. This research revealed that there are legal and institutional constraints to the effective functioning of SIA in Iran, and that there are deficiencies in the operating guidelines. There were serious problems associated with the way SIA was undertaken in all five case studies. Recommendations to improve the policy framework for the conduct of SIA are made. The recommendations advocate for a higher profile of SIA within legislation, for social issues to have greater emphasis in official guidelines for the conduct of EIA and SIA, and for a range of measures to increase the professionalism of SIA practice.  相似文献

As the embodiment of human activities, the change of regional industrial structure is an essential driving factor of global environmental change. Consequently, the research on the change of regional industrial structure and associated effects on the environment is one of the key issues of researches on sustainable development, human–environment relationship, and regional response to global environment change. However, compared to the flourish of researches on environmental impact assessment of industrial departments, few studies have been conducted to assess the environmental impact of regional industrial structure. In this study, based on a synthetic analysis of environmental disturbances of different industrial departments, the environmental impact coefficient of industrial department associated with the index of environmental impact of industrial structure was constructed, so as to make a quantitative assessment of environmental impact of the change of regional industrial structure. And the results of the case study in Lijiang City, a rural region of China, have showed that there are two obvious changes of industrial structure in the study area from 1992 to 2003, associated with a continuous decreasing of the index of environmental impact of industrial structure, which indicated a positive environmental effects of the change of regional industrial structure.  相似文献

The literature concerning Strategic Environmental Assessment (SEA) often refers to the importance of context-specific approaches. However, there is a lack of systematised and consistent studies that enhance tailor-made SEA practices and procedures. Small islands are bounded units of study which may help explore SEA theory and practice in special territories. Small islands present particular features and unique values, such as, small size and population, geographic isolation, limited resources and vulnerable ecosystems. Hence, the main goal of this research was to profile SEA practices and procedures in European small islands and provide a background for future research aiming to improve context-specific SEA applications. To achieve this goal, an exploratory case study was developed using Azores (Portugal) and Orkney (Scotland) archipelagos. An analysis of the corresponding mainland was also carried out to contextualise both case studies. The data collection was achieved through a qualitative content analysis of 43 Environmental Reports. The research found that there is not an SEA context-specific approach used within these European small islands, including guidelines, assessment topics, assessment techniques, follow-up and stakeholders engagement. The debate concerning specific approaches to small islands must be re-focused on the enhancement of SEA capacity-building amongst different stakeholders (including decision-makers), on the development and implementation of collaborative approaches, and on the exchange of knowledge and experiences between small islands networks.  相似文献

对山东省各市2018—2021年的O3污染特征进行了分析,并对2021年5—9月O3污染较重月份空气质量模型的O3预报结果进行了分析评估。结果表明:山东省2018—2021年O3-8 h第90百分位数(O3-8 h-90per)先升高后降低,O3污染呈现波动变化,污染月主要集中在5—9月,并呈现内陆高、沿海低,中北部高、南部低的空间分布特征。集合预报模式对O3模拟效果最好,预测结果与O3监测值的相关性最大、偏差最小,但较难预测出O3的峰值浓度,易漏报O3重度污染。WRF-Chem、CMAQ、CAMx、NAQPMS对O3的模拟效果比集合预报稍差,CMAQ、CAMx存在系统性偏低的情况,但对优级别的模拟效果明显好于其他模式;WRF-Chem、NAQPMS存在系统性偏高的情况,WRF-Chem能较好地模拟出O3超标日,对中度、重度日的24h级别准确率分别达94.08%、100%,对O3超标预报尤其是中至重度污染的预测预报有重要指导意义。  相似文献
