南方某氟化学工业园周围环境中全氟化合物的分布研究

南方某氟化学工业园四氟乙烯(TFE)和聚四氟乙烯(PTFE)的年生产量均达万吨以上,大量氟化学品的生产可能对周围环境产生一定的危害.本文以该氟化学工业园为研究对象,对其周边地区的水体、沉积物中的11种全氟化合物(PFASs)含量进行监测,并首次对植物树叶和树皮中PFASs含量进行测定.结果表明,与树皮相比,树叶对环境中PFASs具有更强的富集能力;水、沉积物、树叶和树皮中最主要的PFASs均是全氟辛酸(PFOA).地表水中PFOA浓度均值为675.9 ng·L-1,最高浓度达1503 ng·L-1;沉积物中PFOA浓度均值为1.11 ng·g-1(干重,下同),最高浓度为2.58 ng·g-l;树叶和树皮中的PFOA浓度均值分别为22.18和15.43 ng·g-1,最高浓度分别为168.6和89.67 ng·g-1.     

高新技术企业集群化的利益机制探讨

高科技含量、小型化、创新型和高投入、高风险是高新技术企业的主要特征。集群化形成的产业区位性和关联性、外部经济性、知识的创造与共享及创新的便利性构成了高新技术企业成长的利益机制。同时，集群化可能存在过度竞争、拥挤效应、对集群资源的过度依赖和集群生命周期的局限等负面影响。高新技术企业应顺应集群化成长大趋势，并做到趋利避害，谋求长期可持续发展。     

武汉城市圈产业经济的系统性分析

摘 要： 构建产业经济的系统性评价指标体系，通过偏离份额方程、产业动态度和偏离度指标对产业结构性和产业演进性这两个维度进行核算，定量揭示武汉城市圈的产业经济发育特征：近20年来，武汉城市圈整体产业结构波动明显，不同城市不同产业在各时段的效益差异明显，呈现一定的圈层结构分异，中心城市武汉增长速度最快，圈域经济发展处于一定的“一极集聚”态势，武汉—鄂州—黄石—孝感城市群产业升级明显，经济发展较快，其余5个城市发展较慢，导致城际产业链群发育不完全，区间产业经济联系较弱；产业结构演进总体上呈现倒“U”型曲线变化规律，中心城市产业结构变动程度差异明显，明显形成3种产业结构演进类型：低偏离度—高结构效益型、中偏离度—中结构效益型、高偏离度—高结构效益型；核心城市武汉的产业结构不断向成熟方向演进，但其它中心城市产业结构仍有待进一步升级优化.     

大都市郊区工业用地减量化适宜性评价方法与实证

工业用地减量化是节约集约用地管理制度下大都市用地转型的必然,也是地方实践在土地整治领域的创新尝试。论文建立大都市郊区工业用地减量化适宜性评价方法,以上海市浦东新区大团镇为例,客观评价其减量化的适宜等级。研究结果表明：1）工业用地减量化的5个影响因素中,污染与能耗因素值差异最大,布局合理性因素值差异最小,主体意愿性因素的空间分布差异最明显;2）218个工业地块划分成5个适宜度等级,随着适宜度提高,相应工业地块零星程度加剧,地块平均规模由适宜度一级的9 507 m²逐渐下降至五级的3 300 m²;3）一级适宜占24.06%,二级适宜占21.51%,三级适宜占29.45%,四级适宜占12.63%,五级适宜占12.35%。适宜等级所占面积的分布接近于正态 分布特征。研究结论：论文所建立方法可作为大都市郊区工业用地退出的评估工具,有助于提高工业用地减量化的统筹协调性。     

Construction of Circular Economy Industrial System

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 shouM 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.     

产业集聚与生态工业园的建设

区域经济发展靠产业集群的支撑。在我国的压缩型工业化进程中，自然资源短缺和环境污染问题日益严重。粗放的经济增长方式维持其可持续性的空间愈来愈小。循环经济是一种新的制度安排和经济发展方式，产业生态化趋向是发展循环经济的重要依托．而产业集聚为产业生态化创造了条件。加强生态工业园的建设能够为产业集群可持续发展提供重要保证。以“3R”为原则．根据资源条件和产业特点，运用循环经济发展方式引导产业集聚。在重、化工产业优先创建生态工业园．按照生产者、“消费者”和分解者的功能引入企业和集聚产业，构成资源循环链．形成具有竞争力的产业集群。改造原有的特色工业园区和高新技术开发区促使其向生态化层次升华．引导新的产业集聚．实现产业集群的升级和可持续发展。对于欠发达地区的资源开发型产业．推行保护性开发。产业集聚与生态园建设并举．形成优势产业集群．促进区域经济发展。

江西产业结构调整与人力资源开发关系实证研究

产盐结构的调整与人力资源开发有着密切的关系，但理论界就人力资源开发对产业发展及结构调整的作用研究得甚少。从江西的定量分析可以看出人力资源开发对江西产业发展及结构调整有促进作用。江西产业结构的进一步调整又对人力资源提出新需求。因此需提出相应的对策。     

OPTIONS FOR ENVIRONMENTAL SUSTAINABILITY OF THE CRUDE PALM OIL INDUSTRY IN THAILAND THROUGH ENHANCEMENT OF INDUSTRIAL ECOSYSTEMS

The crude palm oil industry plays an important role in the economic development of Thailand and in enhancing the economic welfare of the population. Despite obvious benefits of this industrial development, it also significantly contributes to environmental degradation, both at the input and the output sides of its activities. On the input side, crude palm oil mills use large quantities of water and energy in the production process. On the output side, manufacturing processes generate large quantities of wastewater, solid waste/by-products and air pollution. Current industrial wastes and recoverable materials are empty fruit bunches, fibers, shells and ash. It is estimated that in 2003, a total of 2.1 million ton of solid wastes/by-products and 2.5 million m³ of wastewater were generated. The concept of the industrial ecosystem points at the potential of industrial waste recycling resembling food chains, food webs and nutrient cycles of nature. Following the notion of industrial ecology crude palm oil mills can develop a number of waste recycling and reuse systems. This paper analyzes the nature of these industrial ecosystems, divided in in-plant ecosystems (clean technology options) and external waste exchange between crude palm oil industries and other economic activities in Thailand.
