湖泊型水源地管理研究——以苏州市太湖水源地为例

饮用水安全是最大的民生工程,也是自然资源管理研究的热点。基于实地调研、部门访谈和制度条文的梳理与分析,以苏州市太湖水源地为例研究湖泊型水源地管理体制。研究表明：我国水源地管理由国家、省、市、县的法律法规、规章和规范性文件构成相对完善的制度体系,具有水资源和水环境分割管理、流域管理和行政区管理交错的制度特征,初步具备了综合管理的架构;水源保护缺乏流域管治的思维,农村面源污染治理制度支撑不足;在管理手段上以命令控制型手段为主,经济激励与公众参与不足。建立水源地综合管理协调机制,完善经济激励手段,推进公众参与,实施水源地管理共同责任机制将有利于提高水源地管理效率     

关于中国可持续发展综合区划方法的探讨

研究区域可持续发展需要有一个适当的区域划分。本文结合地理学、经济学、生态学等对中国自然地理与杜会经济发展空间差异分析的研究成果．借鉴黄秉维先生所提倡的“自上而下”和“自下而上”相结合的研究思路和方法．以自然区划、经济区划、生态区划．人口区划等四种全国性区划为基础，构建了中国可持续发展综合区划系统。采用叠置与专家评判法首先将全国划分成三大地带．再在三大地带内部划分出N个大区：然后对全国县域（或公里格网）的可持续发展状况进行定量评价．并按类型归并．将归并结果嵌入到N个大区中，用大区的可持续发展等级及地区编号对其命名。     

Ecosystem services assessments in local municipal decision making in South Africa: justification for the use of a business-based approach

The ecosystem services (ES) concept is being increasingly incorporated into environmental policy formulation and management approaches. The Corporate Ecosystem Services Review (ESR) is a framework used to assess the dependence and impact that a business has on ES. The success of the corporate experience of ES assessment provides an opportunity for adaption for local authority decision making. In this paper, the ESR tool was adapted to the South African setting at a local government level, and tested at two sites in the Msunduzi Municipality, KwaZulu-Natal. In testing the tool and gathering feedback from key stakeholders, it was found that there are both opportunities and challenges to this approach. Overall, however, it provides an opportunity for the systematic inclusion of ES assessment into existing regulatory frameworks for land-use planning and Integrated Environmental Management, whether in a strategic application, at a broader spatial (municipal) scale or in a specific locale within the municipality.

Integrated model of simulated occupant injury risk and real medical costs

Introduction

The purpose of this study was to develop an integrated methodology that links occupant injury risk functions, estimated in the laboratory, with real world medical treatment costs by using the abbreviated injury score (AIS). Using our model, the expected medical treatment costs for crash injuries to various body regions and of different severities can be investigated.

Methods

First, the simulation results are compared with NHTSA crash data. We used a modified kinematics simulation model that incorporates an F = E^b function as a supplement to the previous Steffan's model to obtain a more accurate acceleration history a(t). Second, head injury criteria HIC₃₆ can be calculated from a(t), and we use the injury probability P as a function of HIC_36, as proposed by Kuppa, to obtain the injury risk function for various AIS values. Third, medical treatment cost models for various AIS values can be calculated by using a regression cost model with real world data. Finally, the injury risk function and medical treatment cost models are linked through AIS values. We establish an integrated methodology and predict medical costs and car safety data using real world police reports, medical treatment costs, and laboratory simulation results.

Results

Using head injuries in frontal crashes as an example, we focus on simulation parameters for different vehicle models, with and without airbags. We specifically examine impact closing speed, Delta-V, and impact directions.

Conclusion

Simulation results can be used to supplement insufficient real crash data, in particular ΔV, and injury risk results from police crash reports.

Impact on industry

The proposed integrated methodology may provide the vehicle industry with a new safety assessment method. Real crash data coupling provides consumers with more realistic and applicable information.     

PHAST软件在丁腈反应釜定量后果分析中的应用

丁腈反应釜运行过程中若发生泄漏事故,不仅厂区内部,而且附近区域的人员生命与财产都将遭受巨大的损失和危害.过去对一些物质的泄漏后果,人们提出了一些可靠的数学模型,但模型计算量大,容易出错.而采用后果软件PHAST具有很强的操作性.以某化工厂1台丁腈反应釜为例,用DNV公司的PHAST软件预测反应釜中丙烯腈和1,3-丁二烯的混合物发生泄漏后,对周围环境造成的影响.分别讨论了火灾、爆炸和毒性的影响,预测事故危害程度和范围.可为识别主要危险因素,采取相应的安全对策措施,发生事故后的现场控制等提供科学的参考依据.
