A study on ecological operation of web IP industrial chain

In recent years, since the Internet has given rise to mass creation and the intervention of industrial capital, China's web IP has experienced a "blowout" growth, which accelerates the development of the ecological operation of its industry chain a pressing issue, especially in the ecological environment via multi-media and "full-copyright" platforms. In the thesis, the author firstly talks about the ecological operation context of web IP, and then the existing problems of the ecological operation of web IP industrial chain, such as the insufficiency in copyright protection, the economic bubbles on its expansion, the lack of originals and the cash-out mentality toward currency. Therefore, the author comes into the conclusion that, there are enormous potentials for the ecological operation of web IP industrial chain. This demands further platforms across the multiple industrial running of web IP, building its brand through the development of"full-copyright". In one word, the life of web IP would be sustained with ecological progress in multimedia consumption, and the ecological operation of web IP industrial chain would be achieved in fact.

Evolution Analysis and Balanced Coexistence of Ecological Chain

Based on evolution history of earth ecosystem,by studying and analyzing three development stages of natural ecological chain and man-made ecological chain before and after the birth of human beings on the earth,and comparing the energy consumption of human activities and the impact of environmental factors related to natural ecological chain in these stages,following characteristics are found. First,the increasing intelligence of human activities has an increasing impact on the natural ecological chain. Second,the increasing energy consumption of human activities is directly proportional to the degree of natural ecological impact. Third,the traditional production mode of consumption type and the development speed of science and technology are inversely proportional to the change cycle of man-made ecological chain and directly proportional to the degree of ecological crisis. An ecosystem has the ability to regulate,but it has its limits. Beyond this limit,the ecological balance will be destroyed. So,the goal is to transform into a circular type of modern production mode and scientific and technological development as soon as possible,and to shift to a balance between human material requirements and the maintenance and stability of the environment,namely the era of ecological chain of coexistence where nature and human beings are highly harmonious.

To the Question of the Assessment of Ecological Comfort of the Climate

The article is devoted to the discussion of the advantages of assessing the environmental comfort of the climate,based on the natural features of the climate and the bioclimatic conditions of the territory.The study assessed the ecological comfort of the climate in the city of Taganrog on the basis of the developed original sequence of performing three stages of assessing the totality of bioclimatic indicators with the final calculation of the values of the integral indicator of the bioclimatic comfort of the climate.The results of the assessment showed,according to the average long-term climatic data,the presence of sub-comfortable climates with a tendency to transition to comfortable climate conditions in the warm period of the year.The cold season was distinguished by uncomfortable conditions according to long-term average climatic data.Modeling calculations of the possible risk to the health of city residents in the presence of concentrations of suspended solids in the surface air layer,together with carbon monoxide,exceeding the maximum one-time values by more than 7 times,showed that the development of possible resorptive or carcinogenic effects in these circumstances will occur in 1/3 the population of the city.The prospects for the assessment of the ecological comfort of the climate,which allow in the future to adequately calculate the magnitude of environmental risks to public health caused by pollution of the surface air layer,are shown.

再生资源生态全产业链主体界定、现状及对策——基于“源”“流”“汇”的视角

“源—流—汇”生态控制理论能够更好地分析再生资源生态系统的运作状态与过程,论文基于“源”“流”“汇”的研究视角,界定再生资源生态全产业链结构与主体构成,通过多种数据库收集数据与深度访谈调研,研究“源”“流”“汇”三大系统主体发展现状。研究结果发现:“源”系统由于工业固体废弃物产生量逐年上升及生活垃圾产生量持续增加的压力,造成源头减量短时间内难以实现;“流”系统再生资源的回收规模呈上升趋势,而再生资源的综合利用水平较低,致使再生资源化能力整体薄弱;“汇”系统末端处理压力较大。由此,提出提升公众参与意识、发挥再生资源企业规模优势、加快末端处理的相关配套建设等相应的发展对策,以期为实现“产品—再生资源—再生原料—再生产品”一体化“零废弃”的循环系统提供科学参考。

山东省南四湖表层水和沉积物中SCCPs赋存特征及风险评价

短链氯化石蜡(SCCPs)具有良好的化学稳定性和热稳定性,被我国广泛用作金属加工中的润滑剂、密封剂,纺织品中的阻燃剂以及塑料中的增塑剂。但SCCPs的持久性、高毒性、长距离迁移特性和生物蓄积性会对生物体的肝脏、新陈代谢以及发育产生影响,对人类的健康具有潜在危害。目前SCCPs已广泛存在于环境中,然而对其在湖泊淡水环境中的赋存特征及风险评价仍缺乏系统的研究。本文采用GC-MS分析了南四湖表层水和表层沉积物中SCCPs的含量水平、组成特征,探讨了污染物的主要来源及潜在风险。结果表明:①表层水中SCCPs总浓度为53.9~1287.7 ng/L,沉积物中SCCPs总含量为609.9~113761.7 ng/g(以干质量计,下同)。南四湖表层水中SCCPs浓度的空间分布呈现北部较高、南部较低的特征,沉积物中SCCPs含量的空间分布呈现两端高、中间较低的特征。结合南四湖周边环境因素分析,这可能与周边码头船只使用的燃料排放、湖泊水动力、大坝工程以及工业农业生产有关。②C_(10)SCCPs和C_(13)SCCPs是南四湖表层水和沉积物中主要的碳链基团,表层水中Cl_(6)SCCPs、Cl7SCCPs和Cl_(9)SCCPs是主要氯同类物,沉积物中Cl_(6)SCCPs是主要氯同类物。③主成分分析结果表明,南四湖表层水和沉积物中SCCPs的来源关联性较弱,可能与环境条件、人类活动及周边地区生产使用不同种类的氯化石蜡产品等多种因素有关。④熵值法初步风险评估表明,南四湖表层水大部分取样点处于中风险,部分取样点处于高风险,RQ平均值为0.85,整体处于中风险等级。沉积物取样点大部分处于高风险,部分取样点处于中风险,RQ平均值为21.07,整体处于高风险等级。研究显示,南四湖SCCPs污染日益加重,表层水中SCCPs浓度处于中风险等级,沉积物中SCCPs含量总体上已处于高风险等级,需要引起特别的关注。

基于生态风险的土壤短链氯化石蜡环境基准研究

短链氯化石蜡(Short Chain Chlorinated Paraffins,SCCPs)是一种持久性有机污染物,广泛应用于电缆、人造革等工业生产中,具有很强的生物毒性,并可以通过多种途径进入土壤环境,威胁着土壤生态环境安全。针对新污染物之一的SCCPs,已经有相关研究做出了基于淡水环境的基准,而目前关于SCCPs的土壤生态环境基准和风险的研究仍旧缺乏。鉴于此,本研究分别采用物种敏感度分布法和分配系数法推导了土壤中SCCPs的生态环境基准阈值,并对我国典型土壤中的生态风险进行了评价。结果表明:采用物种敏感度分布法得出土壤的无效应浓度为71.46mg/kg;采用分配系数法得到土壤的无效应浓度为10.1mg/kg。经过与相关研究对比,最终选择利用分配系数法得到的基准值作为SCCPs的土壤生态环境基准值。由于物种选择和研究方法的差异性等,本研究获得的SCCPs土壤生态环境基准与其他国家存在一定差异。另外,运用风险商值法对土壤中的SCCPs环境风险进行评价,结果表明,目前我国主要地区的不同土壤类型中SCCPs的HQ值为7.23×10^(-5)~0.5017,为低风险。本研究的结果可为土壤SCCPs环境质量标准的制定与环境风险管理提供参考依据。
