层次分析法在工业园区生态影响评价中的应用--攀枝花市高耗能工业园区生态环境影响探讨

目前生态影响评价研究中的评价对象、内容和方法缺乏统一的模式，本文以攀枝花高耗能园区的开发为例，尝试建立一套系统的工业园区开发生态影响评价方法，该方法以层次分析法为基础，将生态系统分解为经济发展、社会进步、环境保护、景观生态保护四个目标子系统，并在此基础上细化评价因子，通过专家打分和矩阵运算确定其权重，再根据适当的评价标准，运用指数法得出评价结果。结果表明该工业园区在建成前后，其生态综合指数由0．552提高到0．794．其级别由三级提高到二级，说明该园区生态系统总的状态得到改善，该工业园区项目开发可行。     

Improving Operational Planning and Management of National Parks in Turkey: A Case Study

The purpose this study was to improve operational planning and management of national parks in Turkey to balance conservation use and sustainable management. Souksu National Park (SNP) was chosen as the study area. The data were obtained from interviews of 182 visitor groups (in total, 819 people) and analyzed using correlation, factor, discriminant, and regression analyses. It was found that the most important factors affecting operational planning and management of SNP are (1) travel cost, (2) visitor welfare level, (3) intensity of use, (4) size of visitor group, (5) type of recreational demand. The main source of visitors to SNP is from a zone within a 0–90-km radius. This region comprised 53.85% of total visitors to the park. The capital of Turkey (Ankara) is the most important source of visitors from within this zone. The optimum activity mix in SNP is also determined. Picnicking, viewing the scenery, and nature walks or trekking comprised the main uses of the park. It is anticipated that these findings will help to improve operational planning and sustainable management of the national park and the environment.     

化工园区突发环境事件应急预案编制的研究

我国的化工园区为促进经济和社会发展做出了重要贡献。由于化工园区内危险化学品种类多、有毒有害物质数量大、环境风险等级高,存在着发生重特大事故的现实性和可能性。但是,我国至今尚未制定化工园区突发环境事件应急预案编制技术规范,相关研究也未见报道。在当前化工园区安全生产事件高发并严重影响周边环境的情况下,研究化工园区突发环境事件应急预案编制方法,提高应对安全生产事故以及次生突发环境事件的能力尤为重要。通过分析化工园区环境风险物质、环境风险工艺和环境风险受体三个方面的环境风险的特性,初步拟定了化工园区突发环境事件应急预案编制调查评估、建章立制、预案编写三个阶段的技术路线,明确了开展环境风险评估、加强应急能力建设、完善环境风险防范措施和环境应急处置措施的四项编制要点,在此基础上提出了化工园区突发环境事件应急预案由综合预案、现场处置预案、专项预案、环境风险评估报告、环境应急资源调查报告六部分组成的结构框架。     

基于高通量测序的工业园区地下水和土壤细菌群落结构比较研究

为探究工业园区地下水和土壤细菌群落结构、多样性变化特征,采用高通量测序技术对地下水和土壤细菌16S r RNA基因高变区域进行序列测定。通过对Alpha多样性、物种组成、丰度和群落结构的分析,比较地下水和土壤细菌群落结构的异同。Alpha多样性的比较结果表明,土壤细菌群落多样性和丰富度明显高于地下水,地下水细菌群落多样性指数反映出地下水已受到周边污染源的影响。物种注释结果表明,地下水样品共检出48个细菌门,土壤样品共检出50个细菌门。变形菌门(Proteobacteria)、拟杆菌门(Bacteroidetes)和厚壁菌门(Firmicutes)是地下水细菌群落的优势类群,共占93.54%,且该工业园区地下水细菌群落呈现出典型的淡水种群特征;土壤中优势细菌门为Proteobacteria、放线菌门(Actinobacteria)、酸杆菌门(Acidobacteria)、Firmicutes和芽单胞菌门(Gemmatimonadetes),共占85.21%。由于地下水和土壤两者的生态系统和理化环境的差异,致使Actinobacteria、Acidobacteria、绿弯菌门(Chloroflexi)、硝化螺旋菌门(Nitrospirae)、α-变形菌纲(Alphaproteobacteria)、δ-变形菌纲(Deltaproteobacteria)和Gemmatimonadetes占比在地下水和土壤细菌群落间差异显著,同时使地下水和土壤细菌群落各含有一些特有的优势细菌属(地下水2个,土壤4个)。基于高通量测序技术对工业园区样品的测序结果可以为地下水和土壤环境的生态评价提供方法依据。     

改造集散市场 建设新型再生资源回收利用体系

目前“三位一体”（回收网点→分拣中心→集散市场）回收体系模式，因集散市场功能单一、产业链短，不能带动行业走向产业化。回收网点建设适应我国国情，而集散市场成为先进的完整的回收体系的短板。按照示范基地建设标准，把集散市场改造升级为拥有深加工利用产业链，拥有平台支撑优势，能够进行资源的规模化高值化利用的产业园区。把回收和利用两大产业板块融合一体，是再生资源产业化的发展方向。     

Location selection of emergency supplies repositories for emergency logistics management: A variable weighted algorithm

With the development of the city, the number of establishments that are proposed or under construction is increasing year by year, and if they are industries that handle flammable, explosive, toxic, harmful, and dangerous substances, the public safety will face great threats, which will bring great challenges to emergency rescue work. Therefore, providing reasonable solutions to the problem of location selection of emergency supplies repositories are necessary for improving the emergency response efficiency in chemical industrial parks. A mathematical model for location selection of emergency supplies repositories in emergency logistics management are presented considering more actual factors. The optimization objectives of the model are to minimize total transport length and cost. And then a Variable Weighted Algorithm is designed to solve the model, where an auxiliary function was constructed with different methods of building weighting factors based on the theory and method of solving multi-objective optimization problems in operational research. Simulation results show the effectiveness and feasibility of the models and algorithms presented in this paper.

The Quagga Mussel Crisis at Lake Mead National Recreation Area,Nevada (U.S.A.)

Abstract: Parks are cornerstones of conservation; and non‐native invasive species drive extensive changes to biological diversity in parks. Knowing this, national park staff at Lake Mead National Recreation Area in the southwestern United States had a program in place for early detection of the non‐native, invasive quagga mussel (Dreissena rostriformis bugensis). Upon finding the mussel in January 2007, managers moved quickly to access funding and the best available science to implement a response. Managers considered four options—doing nothing, closing the park, restricting movement on the lakes, and educating and enforcing park visitors—and decided to focus on education and enforcing existing laws. Nonetheless, quagga spread throughout the park and soon began to appear throughout the western United States. I examined why efforts to control the expansion failed and determined the general lessons to be learned from this case. Concentrating human visitation on the lakes through land‐use zoning opened a pathway for invasion, reduced management options, and led to the rapid spread of quagga. To reconcile competing mandates to protect nature and provide recreation, zoning in parks has become a common practice worldwide. It reduces stress on some areas of a park by restricting and thus concentrating human activity in particular areas. Concentrating the human activity in one area does three things: cements pathways that repeatedly import and export vectors of non‐native invasive species; creates the disturbed area necessary to enable non‐native invasive species to gain a foothold; and, establishes a source of invasions that, without appropriate controls, can quickly spread to a park's wilderness areas.     

基于品牌创建模型的主题公园可持续发展研究

通过对主题公园研究文献的综述分析,指出主题公园研究中品牌化研究较为匮乏.而中国主题公园近二十年的发展历程表明,主题公园存在的生命周期短暂性现象的主要原因是缺乏品牌创新.从生命周期及可持续发展的视角,提出了以品牌为核心的主题公园运营模式,以此为指导构建了包括概念层、主体层以及基础层三个层面的主题公园品牌创建模型,即通过对动态市场的研究,设计、宣传和推广自身的原创品牌,在获得相应的品牌价值之后,将品牌价值向外延伸,通过系统内各部分的紧密合作,获得主题公园可持续发展的内在驱动力.最后,着重从原创品牌的构建、品牌价值的延伸和保障因素兰方面,提出了基于品牌创建模型的主题公园可持续发展策略.该策略表明:主题公园必须在丰厚的文化内涵和更高的游客体验价值基础上强化自身品牌的构建和发展,在品牌站稳于市场时要适当适度地进行品牌价值延伸,这才能保证主题公园经营的可持续发展.     

香港典型地质遗迹资源与地质公园建设

香港素以金融、商业贸易中心闻名于世界,但香港境内所发育的曲折有致的岩石海岸、幽远宁静的海滩、巍峨多姿的群山、造型奇异的岛礁,弥足珍贵的自然生态和地质遗迹资源却鲜为人知。本文在对香港地质概况进行简单介绍的基础上,对香港地质遗迹资源进行系统分类和对比分析,指出西贡万宜水库至果洲群岛方圆近150 km2范围内发育的十分典型、极具规模的六方柱状节理构造景观是世界上同类岩石中罕见的地质现象,其分布面积大,露头完整,具有稀缺性、独特性和典型性,最后对香港国家地质公园一个公园,两个园区,八个景区的空间结构及每个园区的主要地质遗迹资源进行了系统归纳总结。香港国家地质公园的建立很好的起到了保育地质多样性的首要目标,同时很好地推动了香港的地质教育和科普发展。
