The Convergence Analysis on the Economic Growth and Energy Intensity Gap between Regional Sectors

In this paper,the authors have analyzed the relationship between energy intensity gap and GDP per worker gap of China’s western and eastern provinces over the period 1997-2006.Using panel data model with lag adjustment,taking the above provinces and six industrial sectors (agriculture,forestry,animal husbandry,and fisheries,industry,construction industry,transport,storage and post & telecommunications,wholesale and retail trades & catering industry,and other sectors of tertiary industry.) as the investigated subjects,the authors have conducted empirical study on the convergence of GDP per worker gap and the convergence of energy intensity gap with respect to the variation of GDP per worker gap,and have concluded that:First,the GDP per worker gap of the six industrial sectors and provinces are convergent,and of this,the convergence rate of GDP per worker gap of Construction Industry is the fastest,while that of Industry is the slowest.Second,the overall energy intensity gap between eastern and western provinces is convergent,that is,with the narrowing of GDP per worker gap between eastern and western provinces,the energy intensity gap converges,but its convergence rate is slower than that of GDP per worker gap.Third,energy intensity gap between various industrial sectors of the east and the west is either convergent or divergent,and there are differences.The energy intensity gap of agriculture,forestry,animal husbandry,and fisheries,industry,and construction industry is convergent,while that of the other three industrial sectors is divergent.Fourth,the convergence of the overall energy intensity of the western provinces is not in conformity with the convergence of the various industrial sectors,and there are significant differences,indicating that the western provinces and autonomous regions should take measures to more effectively improve their overall energy utilization efficiency at the industrial sector level.

Local Area Quotas for Industrial Emissions along Reaches of the Pearl River in Guangdong

There is an obvious departure from the regional equilibrium of developments between the upper and lower reaches of the Pearl River in Guangdong, which resulted in ＂the effects of contra-geography-grads development＂. It is mainly because the upriver mountainous areas have been deeply stuck in industrialization delay and marginalization plights, so that nearly 40 million local people have conceived a dream to get rid of ＂the vicious circle of poverty＂ by speeding up industrial development. But the problem is that such industrialization efforts on a large scale in mountainous areas are encountering the bottleneck of environmental capacity that strictly limits industrial emissions along the upper reaches of any water system. As a solution, an institutional arrangement called ＂the Local Area Quotas for Industrial Emissions along the Pearl River＂ is put forward supposed to give corresponding compensation to the rights of industrial development yielded by some areas with lower environmental capacity through the distribution and trading of IDQs.     

碳源对工业污染场地土壤中HCHs和DDTs降解的促进作用

我国对有机氯农药的大量需求使得在农药生产、加工和分装等过程中造成了许多城镇中存在有机氯农药污染场地,限制了土地的后续开发利用.本研究选取3种类型的碳源组成有机修复剂A、B、C,添加到受有机氯工业污染场地土壤中进行微生物降解试验,并对比了3种修复剂的效果.试验过程中,反应体系水分含量为50％,添加零价金属调节氧化还原电位,采用好氧/厌氧交替循环方式进行生物降解.实验结果表明:3种修复剂对HCHs和DDTs的降解都有显著促进作用.与DDTs相比,HCHs较易降解.90 d内,添加修复剂(A、B、C)的处理中∑HCH的浓度分别从73.37~85.71 mg·kg^-1降解到了15.88~38.21 mg·kg^-1.与未添加修复剂的对照相比较,∑HCH的降解率提高了19%~52%,90 d内,ΣHCH的降解率最高可达81%.添加修复剂(A、B、C)的处理中ΣDDT的浓度分别从91.68~119.79 mg·kg^-1降解到了45.1~60.7 mg·kg^-1,相对未添加修复剂的对照试验,∑DDT的降解率提高了39%~45%,30 d内∑DDT的降解率最高可达到51%,但30 d后降解效率无明显增加.就不同类型碳源的促进作用来看,C/N最高,而含水率最低的修复剂B的效果最好,而C/N比最低而含水率最高的修复剂A效果最差.

工业园区TVOC和恶臭的电子鼻检测技术研究

根据工业园区中TVOC和恶臭可能存在的主要气体组分,筛选传感器阵列,构建用于检测工业园区内TVOC和恶臭的电子鼻系统.本研究设计了TVOC污染指数（TPI）和恶臭污染指数（OPI）及基于电子鼻的现场检测方法.在此基础上,结合嘉兴市乍浦港区内化工园区污染情况分析,选择6个检测点进行现场检测,各传感器响应值经PCA分析,提取了2个主成分即可将8个传感器分为2类：TVOC型（S1）和恶臭型（S2～S8）.将现场采集的气体样品用GC/MS进行定性分析,各采样点TVOC物质积分面积百分比在10%以上的累积起来大多都占总面积的90%以上,而恶臭类物质则大多都在10%以下.结果表明：①选用合适的传感器阵列,结合PCA分析,可以初步反映工业园区内TVOC和恶臭的污染情况;②结合电子鼻测得的污染指数与GC/MS定性分析结果,可以大体得出工业园区TVOC和恶臭总体污染情况及各种污染物分布情况;③电子鼻和GIS技术综合应用到工业园区TVOC和恶臭的检测,能初步用于评估工业园区空间污染情况.     

基于热异常遥感的冀南城市群工业能耗及大气污染

选取冀南城市群为研究区,基于2012~2016年VⅡRS卫星数据热异常点产品,结合工业能源消耗量、工业废气排放量以及空气质量数据,利用统计分析和空间分析探讨热异常点辐射强度的变化规律及其与工业能源消耗、污染物排放之间的关系.结果表明,热异常点的辐射强度可以表征工业能源消耗量,并间接反映工业生产规模与污染排放水平.辐射强度越大,工业生产规模越大.辐射强度与工业SO₂排放量呈较高的正相关,与NO_x排放量呈中度线性相关.PM₁₀、SO₂及NO₂浓度与工业能源消耗和热异常点辐射强度灰色关联度均较高.工业生产活动产生的污染物中,颗粒物对大气污染的贡献最高,其次为SO₂.2012~2016年,邯郸、石家庄以及廊坊的工业生产空间分布呈逐年收缩聚集的趋势,保定和沧州的工业生产分别出现向南、向西迁移趋势.
