Research on the Industrial Symbiosis Supporting System of Eco-industrial Park

The establishment and development of the industrial symbiosis of eco-industrial park are affected by several factors. Based on the formed industrial symbiosis supporting system chart, this article analyzes the microcosmic supporting system and macroscopic supporting system. In the microcosmic supporting system, it elaborates five aspects including key enterprises, service intermediaries in the park, symbiotic enterprises, competitors and the public in detail. Then it describes the macroscopic supporting system from four aspects of governmental participation, technological innovation, educational promotion and cultural support. Finally, combining with the current construction status of the ecoindustrial park in China, it proposes the countermeasures and suggestions to build the supporting system for the eco-industrial park and provides theoretical support for the faster and better construction of the eco-industrial park in China.     

基于科学发展观的安全哲学思考

从科学发展观的理论视角出发,论述安全发展观的哲学内涵:辩证统一的安全利益关系,工人、企业责任人和安全监督人员等不同安全主体应树立正确的安全利益观;统筹安全社会技术系统,统筹不同安全行业,统筹人员、机械设备、环境和管理等安全要素;安全发展观的贯彻落实依靠安全可持续;建议树立全面、协调、可持续的安全发展观。采用系统思考方法构建安全系统动力学模型,在人员、机械设备、环境、管理4个变量因子的影响下,安全系统安全度水平下降,造成安全系统从可持续安全状态进入临界可持续安全状态,最终跃迁到不可持续状态,导致伤亡事故发生,并结合安全木桶安全要素讨论仿真结果。     

Cd-tolerant Suillus luteus: A fungal insurance for pines exposed to Cd

Soil metal pollution can trigger evolutionary adaptation in soil-borne organisms. An in vitro screening test showed cadmium adaptation in populations of Suillus luteus (L.: Fr.) Roussel, an ectomycorrhizal fungus of pine trees. Cadmium stress was subsequently investigated in Scots pine (Pinus sylvestris L.) seedlings inoculated with a Cd-tolerant S. luteus, isolated from a heavy metal contaminated site, and compared to plants inoculated with a Cd-sensitive isolate from a non-polluted area. A dose-response experiment with mycorrhizal pines showed better plant protection by a Cd-adapted fungus: more fungal biomass and a higher nutrient uptake at high Cd exposure. In addition, less Cd was transferred to aboveground plant parts. Because of the key role of the ectomycorrhizal symbiosis for tree fitness, the evolution of Cd tolerance in an ectomycorrhizal partner such as S. luteus can be of major importance for the establishment of pine forests on Cd-contaminated soils.     

Environmental and economic assessment of a greenhouse waste heat exchange

As the economic costs of energy and the negative externalities associated with the combustion of fossil fuels threaten the economic viability of greenhouses in northern climates there is a renewed interest in the use of waste heat. This paper presents a technical and economic methodology to determine the viability of establishing waste heat greenhouses using the waste heat from industrial processes in northern climates. A case study is presented of an exchange between a tomato greenhouse and a flat glass manufacturing plant, which found the waste heat system is significantly more economic to operate than a purely natural gas system.     

Implementation of the ecosystem services approach in Swedish municipal planning

While ecosystem-based planning approaches are increasingly promoted through international and national policies, municipalities are still struggling with translating them into practice. Against this background, this paper aims to increase the knowledge of current advances and possible ways to support the implementation of the ecosystem services (ES) approach at the municipal level. More specifically, we analyze how ES have been integrated into comprehensive planning within the municipality of Malmö in Sweden over the last 60 years, a declared forerunner in local environmental governance. Based on a content analysis of comprehensive plans over the period 1956–2014 and interviews with municipal stakeholders, this paper demonstrates how planning has shifted over time toward a more holistic view of ES and their significance for human well-being and urban sustainability. Both explicit and implicit applications of the ES concept were found in the analyzed comprehensive plans and associated programs and projects. Our study shows how these applications reflect international, national, and local policy changes, and indicates how municipalities can gradually integrate the ES approach into comprehensive planning and facilitate the transition from implicit to more explicit knowledge use.     

基于土地利用视角的乡村居业协同多尺度分析——以徐州市为例

“乡村振兴”战略是解决城乡发展不协调、乡村发展不充分问题的重要抓手。居业协同作为乡村人居融合发展的高级形态,其程度能够反映乡村振兴的质量与成效。采用土地利用数据从结构和利用两个维度探索淮海经济区中心城市徐州三个尺度下的居业协同格局,结果表明：（1）徐州市土地在供给方面表现出居业失衡,宅基地供给相对于经营性建设用地优势明显;但由于使用中宅基地的空废,二者利用状态表现得更协同。（2）不同空间尺度下,居业协同状态有所差异,其中乡镇尺度居业空间关系较为稳定,基本维持相对平衡,本文认为乡镇是土地资源配置、实施乡村振兴战略的最佳尺度。（3）后续研究中,居业用地适宜的比例及农用地对居业协同的影响都需要进一步探索。     

老庄道家思想所蕴含的生态伦理观念

中国古代思想家老子、庄子在生态环境伦理方面就如何协调人与自然的关系提出了许多宝贵的思想,如“天人合一”、“道法自然”、“知止”等。这些观点对我们解决二十一世纪所面临的生态环境问题具有重要的启迪意义。     

民众环境意识是环境教育的核心与目的

当前“低碳经济”、“低碳生活”等理念在众多媒介有大量的表述和宣传报道。但抽样调查显示，实际上广大公众对于“低碳”的认知却颇有一些不甚清晰明了。概念的模糊性及不确定性，势必影响并阻碍我们积极倡导和实践推进生态文明建设，努力实现清洁发展、安全发展、绿色发展及可持续发展。

旅游地的类生命特征研究

把旅游地视为一个特殊生命体和特殊的生态系统．旅游地与生物体存在非常类似的机理。具有旅游地生命周期、旅游地生态系统、旅游地之间存在诸如共生、竞争、寄生、捕食生态空间关系等明显的类生命特征。研究旅游地的类生命特征．为运用生态学理论研究旅游发展问题提供了可靠依据和切实可行性，为更好地解释和透视旅游发展问题实质提供了崭新的途径与思路，生态学理论在旅游中的应用和解决旅游问题具有现实的可能性和潜在的应用价值，在丰富旅游学与生态学理论的同时，指导并促进旅游业的可持续发展。
