建设国际化大都市过程中的经济与资源和环境协调发展的研究

广州市有2200多年历史,是1982年国家首批公布的历史文化名城之一。1992年被世界大都市协会接纳为会员城市,是目前中国唯一被接纳为会员的城市。要达到现代化大都市的水平必须与整个世界经济的市场体制和产业接轨,为此广东省建立了珠江三角洲经济区,把广州市列为中心城市,并计划化15年时间将广州建成现代化国际化大都市。从世界各国国际大都市发展的历程看,表现为物流、能流和人流的集中和分散过程,实际是经济与资源和环境协调的发展过程。历史上曾经有过美国洛杉矾的光化学烟雾事件,日本东京50～70年代经常发生的硫酸烟雾和光化学烟…     

自然环境资源有偿使用的对策措施

从自然环境资源的自然再生产和社会再生产、以及直接劳动和间接劳动等方面,论证了自然环境资源具有价值,从而为有偿使用提供了理论依据;并进一步揭示了造成自然环境资源危机的重要原因是其价值实现不足。人类在长期发展过程中,以牺牲环境和浪费资源为代价,获取了“虚假利益”;最后提出了自然环境资源实行有偿使用的对策措施。

环境污染问题对资源型城市发展的制约与应对策略分析

资源型城市经济快速发展的同时,存在的环境污染问题均较为严重.为维持城市经济的可持续发展,资源型城市实施战略转型势在必然,在这个过程中,环境保护必须纳入转型战略整体规划中.以钢都攀枝花为例,分析了资源型城市发展中的环境制约因素,强调在转型战略中应充分考虑环境保护和生态恢复等问题,并提出循环经济、清洁生产等是攀枝花市资源型城市战略转型中可采取的缓解环境危机、实现经济与环境协调发展的有效措施.     

基于预警视角的南京市资源环境承载力评价研究

参考国家相关指南并结合南京市实际,以区级行政区为评价单元对南京市进行资源环境承载力评价。基于预警视角从资源、环境、生态等维度选取典型指标构建评价指标体系,分别进行针对资源、环境与生态的基础评价和针对农产品主产区的专项评价。采取"短板效应",结合基础、专项评价结果进行南京市资源环境承载力集成评价,为南京市资源环境承载力评价预警工作提供基础数据支撑,并从水资源、土地资源、大气环境、水环境、生态系统等方面进行超载因子识别与分析,提出相应的管控对策建议。

Parathion degradation and its intermediate formation by Fenton process in neutral environment

The purpose of this study is to investigate parathion degradation by Fenton process in neutral environment. The initial parathion concentration for all the degradation experiments was 20 ppm. For hydrogen ion effect on Fenton degradation, the pH varied from 2 to 8 at the [H₂O₂] to [Fe²⁺] ratio of 2-2 mM, and the result showed pH 3 as the most effective environment for parathion degradation by Fenton process. Apparent degradation was also observed at pH 7. The subsequent analysis for parathion degradation was conducted at pH 7 because most environmental parathion exists in the neutral environment. Comparing the parathion degradation results at various Fenton dosages revealed that at Fe²⁺ concentrations of 0.5, 1.0 and 1.5 mM, the Fenton reagent ratio ([H₂O₂]/[Fe²⁺]) for best-removing performance were found as 4, 3, and 2, resulting in the removal efficiencies of 19%, 48% and 36%, respectively. Further increase in Fe²⁺ concentration did not cause any increase of the optimum Fenton reagent ratio for the best parathion removal. The result from LC-MS also indicated that hydroxyl radicals might attack the PS double bond, the single bonds connecting nitro-group, nitrophenol, or the single bond within ethyl groups of parathion molecules forming paraoxons, nitrophenols, nitrate/nitrite, thiophosphates, and other smaller molecules. Lastly, the parathion degradation by Fenton process at the presence of humic acids was investigated, and the results showed that the presence of 10 mg L⁻¹ of humic acids in the aqueous solution enhanced the parathion removal by Fenton process twice as much as that without the presence of humic acids.
