负载有度:论环境法的生态承载力控制原则

可持续发展要求社会经济适度发展的同时,环境质量不退化.为达到这一目标,在环境管理中就必须以生态承载力为标准判断经济发展的规模和速度是否具有正当性和合理性,这是化解经济发展与环境保护矛盾的关键所在.环境法应当把生态承载力控制作为一项基本原则,要求人们对环境问题的预防应当以生态承载力为依据,确保向环境排放污染物的总量不得超过环境容量,并保证开发、利用自然资源不能超过生态环境在一定时期内的供给能力.这是对执法者在处理经济发展与环境保护的矛盾中所享有的过大的自由裁量权的必要制约.然而,生态承载力控制原则的实施难度较大,除了需要立法的明文规定外,还应当注重研究、建立生态承载力的核算方法体系;此外,还应当对现行环境执法体制进行改革,促使地方环保部门在环境执法中摆脱地方保护主义的不当干涉,并积极加强公众参与,通过公众监督杜绝突破生态承载力的决策的制定和实施.     

Construction of Circular Economy Industrial System

Abstract

It is difficult to realize the transformation from traditional economy industrial system to circular economy industrial system. Regarding primary raw materials as the indicators, the industrial system has been specified according to the divergence among the indicators and the circular utilization modes. In comparison with the association among industrial systems, the relationship among industrial sub-systems is named as industrial cross-linking in this paper. The industrial system which could completely utilize and recycle the indicators should be increased and strengthened, and the circular economy industrial system with complete industrial association and industrial cross-linking should also be constructed. Taking the development of circular agricultural system basing on the traditional agricultural system as an example, the traditional agricultural products are regarded as the indicators which have been divided into foodstuff and crop straws which are used to produce food and articles for use, like fertilizer, energy and papers etc. The way to construct the circular agricultural industrial system is to increase the industrial systems that could utilize the products generated from crop straws, feces and other castoffs and transform the wastewater and other trucks into environmental friendly products. It has also been pointed out that the construction of circular economy industrial system is conducive to the foundation of circular industrial economics and the establishment of the construction layout of circular economy and the application schemes. Suggestions to the theoretical and practical work of the next step have also been brought forward in this paper.     

On the Law Right of the Gas Water of Water Resources

Abstract

With the development of science and technology, the researches and application of water resources including the gas water have been constantly developed. Through an analysis on the flaws of the water right theory, and by executing reconstruction and renewal of the theory and system of water right in modern society, the water right position of the gas water will be established, leading to the maturity of the whole law effectiveness and substantial results of water right.     

Thermal rehabilitation of Romanian housing: a low cost assessment tool

The numerous buildings that currently require thermal rehabilitation in Romania means that substantial resources and a large number of competent people are required to carry out surveys and energy audits. However, commercial energy balance software is mostly unaffordable for those organisations involved in this process. This paper describes an energy balance programme – ENEFControl – developed to be a rapid, low cost, local tool able to assist in the choice of energy efficient solutions for buildings. To test the software, thermal and energy analyses were carried out on a 1970s built apartment block in Transylvania. Based on these analyses, three constructive scenarios were proposed for thermal rehabilitation. Compared to the performance of the analysed building, the thermal and energy performance of the retrofitted building in all three scenarios significantly improved. Since European Union accession in 2007, rapidly rising energy costs have affected the Romanian population. ENEFControl offers Romanian engineers and architects an opportunity to speed up the rehabilitation programme of buildings without the need for more expensive expertise and tools.     

Investigating the use of green design parameters in UAE construction projects

Construction practices tend to have an adverse impact on the environment through their contribution to CO₂ emission, increased waste and energy consumption. The United Arab Emirates (UAE) has launched many initiatives to encourage green design over the past years and to work towards a sustainable community. Nonetheless, such initiatives require a considerable amount of time to penetrate the professional psyche and showcase real results that are easily utilised by the construction community. The aim of this research was to study the current degree of use of Green Design Parameters (GDPs) in the UAE construction projects and to identify the main constraints that hinder their application. To achieve the study's objective, a survey was designed and distributed to engineering design professionals in different consulting and contracting companies in the seven emirates of the UAE. Feedback from 112 projects was examined and statistically analysed. The analysis showed a degree of awareness and use of some key GDPs. Moreover, the data showed no correlation between the degree of using GDPs in a project and its cost and schedule. Not surprisingly, the lack of knowledge about green parameters and the lack of trust in recycled materials are the main constraints that featured in the responses.     

富水红砂岩地层隧道联络通道冻结温度场分布规律及其敏感性分析*

为了明确富水红砂岩地层中冻结温度场的影响因素,研究温度场的发展和分布规律,以兰州地铁2号线定西路站到五里铺站之间的隧道联络通道为研究背景,建立三维瞬态温度场有限元模型对冻结加固过程进行模拟,通过数值模拟和实测数据对比验证模型的准确性进而分析土体密度、导热系数、比热容的变化对温度场发展的影响。通过灰色关联分析法,得到各土体参数对温度场发展的影响程度。研究结果表明:冻结孔越密集,形成的冻结帷幕越厚,冻结壁温度越低;随着导热系数增大,形成的冻结壁温度降低,随着土体密度和比热容增大,形成的冻结壁温度升高;影响温度场温度的各参数灰色关联度排序为:比热容>密度>导热系数;当各参数分别增大30%时,温度场温度变化程度排序为:密度>导热系数>比热容。研究结果可为类似地质冻结工程的设计施工及土体改良提供参考依据。     

人群应急疏散模型构建及疏散效率分析研究*

为更系统地分析社会网络内预警传播对人群疏散效率影响,以江苏德桥仓储有限公司“4·22”较大火灾事故为背景,构建人群应急疏散模型,模拟不同预警策略应用下社会预警传播及人群疏散动态过程,分析不同情景动态演化特征。研究结果表明:高效预警策略确保多数人被预警、疏散的同时,会造成人群集聚性疏散,引发严重交通拥堵,需采取有效方法降低交通实时承载量,保障疏散速度,进一步提升疏散效率。研究结果可为完善应急疏散方案提供借鉴。

我国生态环境保护综合行政执法问题研究?——基于法律文本的量化分析

生态环境执法是生态环境治理的核心内容,随着我国综合行政执法的推进,环境领域也步入综合执法改革阶段。生态环境综合执法改革仍处于改革的初期,需要逐步调整和完善。本文以《生态环境保护综合行政执法事项指导目录（2020年版）》列出的相关法律文本为研究对象,构建基于生态环境执法内容、执法阶段和执法方式的分析框架。通过对生态环境综合执法法律文本的编码和量化分析,发现生态环境综合执法涉及的内容较为全面,执法方式涵盖面广,但是存在法律法规不健全、生态保护执法不足、全过程执法欠缺、执法方式较为单调等问题。后续需要完善相关法律条目,增加生态保护领域的执法,加强全过程管控阶段的执法,丰富除罚款外的执法方式。     

Les Reciproqueteurs: post-regulatory corporatism

ABSTRACT

Reflexive governance can be understood as an emergent encapsulated trust-building corporatism where network participants are neither state functionaries nor market entrepreneurs but network reciproqueteurs. This paper argues that such reflexive network governance results in a post-regulatory corporatism (PRC)—a more adaptable, less formalized, and flexible mode of interest intermediation, policy-making, and policy-implementation than previous modes of corporatist intermediation. Functional differentiation processes engender ‘negotiated connected contracts' in rescaled space in between inter-regional assemblages, a mode of structurally coupling new social partners in the emergent transnational knowledge-based economy. This involves the building of new social capital of network trust-building manifested in the norms of reciprocity and reflexive law constituted as a new mode of protocolism: one associated with the social learning and policy designing necessary for ecological systems' autopoeisis, resilience, and sustainability. This paper conceptualizes reflexive network governance as protocolism in constellations of PRC and discusses examples from the area of environmental policy-making. PRC is understood as a new mode of negotiated rule-making: as a recursive protocolism of multi-stakeholder social pacts constituted by frame agreements and negotiated connected network contracts.
