安徽省合肥和芜湖市对外经济联系量与地缘经济关系匹配分析

引入克鲁格曼指数、建成区面积、人口素质权重系数等指标修正了以往的引力模型,利用修正的引力模型确定城市的对外经济联系量。运用欧氏距离法确定城市间的地缘经济关系,并分析其形成的原因。对经济联系量与地缘经济关系进行匹配,并对匹配结果进行原因分析,根据不同的匹配情况提出城市未来发展战略。研究结果显示：(1)合肥市的地缘经济关系互补性大于竞争性,而芜湖是竞争性大于互补性;在地缘经济关系的形成过程中,产品资源向外地的流动能力指标对形成城市间竞争性或互补性的贡献较大。(2)合肥、芜湖两市的地缘经济关系和外联经济联系量的匹配结果都不理想,属于强、较强经济联系量与强、较强互补地缘经济关系的理想匹配结果较少;城市间产业结构的差异性和交通的便捷性成为影响匹配结果的一个原因。增强经济联系量、调整地缘经济战略、优化匹配关系是城市的首要任务

Was Contamination of Southern California Groundwater By Chlorinated Solvents Foreseen?

The historical record does not support the argument that the cause of widespread groundwater contamination by chlorinated solvents in southern California was an inability to anticipate or detect the problem. The propensity of industrial wastes, including chlorinated solvents, to contaminate groundwater was understood by the 1940s in southern California. This understanding was not limited to a small group of specialists, but extended to regulators, industry, and the interested public. Industrial waste disposal was deregulated in 1949 as a result of lobbying by industry, despite a warning from the director of the State Health Department that such action would create "a backlog of water pollution over the State that will constitute a plague comparable to the air pollution in Los Angeles". Regulators warned specifically about the danger that groundwater pollution in the San Fernando and San Gabriel valleys would result from improper disposals of industrial chemicals, and solvents were identified as major contaminants in the scientific literature. Analytical methods to detect chlorinated solvents in groundwater at the concentrations found near the DNAPL (dense non-aqueous phase liquids) source zones have been well known since at least 1950, and a method with a detection limit of 10 w g/L was published as early as 1953.     

典型建筑固体废弃物再生骨料对环保砖性能的影响

随着我国城市化和工业化进程的快速推进,城市建设产生大量的建筑废弃物,燃煤电厂产生大量炉底渣,建筑固废的处置在城市可持续发展过程中备受关注。以建筑垃圾再生骨料、炉底渣和石粉等区域特色的骨料制备环保砖,系统考察了骨料对环保砖力学性能的影响。实验结果表明,再生骨料的种类对环保砖抗压强度的影响显著。再生骨料中混凝土的增加,环保砖抗压强度逐渐增加;而再生骨料中粘土砖含量的增加,环保砖抗压强度明显降低。环保砖抗压强度随炉底渣的含量增加而降低,石粉对环保砖抗压强度有提升作用。

What’s the Problem? River Management,Education, and Public Beliefs

This paper invokes the theory of planned behavior (TPB) as a diagnostic tool to explain an existing public education program's limited success at improving river water quality in the City of Perth, Western Australia. A reflective, client-driven research approach was used. A facilitated expert workshop defined an environmental problem (excess nutrients leaving gardens and entering waterways) and a desired behavior (residents purchasing environmentally sensitive fertilizer) to address the problem. A TPB-based belief elicitation survey captured respondents' beliefs regarding the desired behavior. The findings suggest respondents were aware of the links between purchasing environmentally sensitive fertilizer and river water quality. However, this behavior is compromised by the challenges in identifying appropriate products, product quality concerns, and cost. Viewing the content of a public education program through the lens of the TPB reveals insights into how and why the program fell short in achieving one of its key behavioral change goals.     

Phyt'Eaux Cités: application and validation of a programme to reduce surface water contamination with urban pesticides

This paper presents first results of Phyt’Eaux Cités, a program put in place by the local water supply agency, the SEDIF (Syndicat des Eaux d’Ile-de-France), in collaboration with 73 local authorities, private societies and institutional offices (365 km²). The challenges included: measurement of the previous surface water contamination, control of urban pesticide applications, prevention of pesticide hazard on users and finally a overall reduction of surface water contamination. An inquiry on urban total pesticide amount was coupled with a surface water bi-weekly monitoring to establish the impact of more than 200 molecules upon the Orge River. For 2007, at least 4400 kg and 92 type of pesticides (essentially herbicides) were quantified for all urban users in the Phyt’Eaux Cités perimeter. At the outlet of the Orge River (bi-weekly sampling in 2007), 11 molecules were always detected above 0.1 μg L⁻¹. They displayed the mainly urban origin of pesticide surface water contamination. Amitrole, AMPA (Aminomethyl Phosphonic Acid), demethyldiuron, diuron, glyphosate and atrazine were quantified with a 100% of frequency in 2007 and 2008 at the Orge River outlet. During the year, peaks of contamination were also registered for MCCP, 2,4 MCPA, 2,4 D, triclopyr, dichlorprop, diflufènican, active substances used in large amount in the urban area. However, some other urban molecules, such as isoxaben or flazasulfuron, were detected with low frequency. During late spring and summer, contamination patterns and load were dominated by glyphosate, amitrole and diuron, essentially applied by cities and urban users. Both isoproturon and chlortoluron were quantified during autumn and winter months according to upstream agricultural practices. In conclusion, 3 years after the beginning of this programme, the cities reduced the use of 68% of the total pesticide amount. An improvement on surface water quality was found from 2008 and during 2009 for all pesticides. In particular, glyphosate showed a decrease of the load above 60% in 2008, partly related to the Phyt’Eaux Cités action.
