支撑环境污染第三方治理的标准体系构建研究

采用系统论及系统工程方法论,结合我国环境污染治理标准制定情况,构建了科学合理的支撑环境污染第三方治理的标准体系。标准体系包含4个子体系及22个专业领域,体系的建立可为形成环境污染第三方治理相关的共性技术、管理与服务标准提供理论参考。通过标准梳理工作,确定未来迫切需要制定一整套环境污染第三方治理绩效评价的相关标准。该研究成果能够强化环境污染第三方治理效果,完善环境污染第三方治理机制体制,对规范环境污染第三方治理技术与服务市场化应用具有一定的参考价值。     

废旧轮胎再制造过程的环境污染及防治研究

随着汽车和轮胎行业的迅速发展,由此产生的废旧轮胎也逐年增加。废旧轮胎再利用技术既可解决橡胶资源短缺问题,又能消除黑色污染,是循环经济的重要环节,在推广这一技术的同时,应注意其伴生的环境污染。再利用生产主要分为清洗、打磨、粘中垫胶、粘预硫化胎面、低温硫化等步骤。此过程将产生粉尘、非甲烷总烃废气、橡胶颗粒以及清洗废水等污染物。应对这些污染物采取有效的治理措施,使其满足达标排放和无害化的要求,以达到经济利益和环境保护的双赢。     

Examining adaptation and mitigation opportunities in the context of the integrated watershed management programme of the Government of India

India occupies 2.4% of the world’s geographical area with a large percentage of its land under agriculture. About 228 Million hectares (Mha) of its geographical area (nearly 69%) fall within the dryland (arid, semi-arid and dry sub-humid) region. Of the total cultivated area of 142 Mha, major part of agriculture in the country is rainfed, extending to over 97 Mha and constituting nearly 68% of the net cultivated area, therefore making the agricultural sector vulnerable and exposed to the vagaries of weather conditions. Climate change adds to this dimension of stress. A strong need is felt for targeting programmes in these areas that address issues related to employing suitable soil and water conservation measures. In this context this paper seeks to examine the case for watershed development as an adaptive strategy. An examination of the possibility of fortifying the existing programme with a view to adapting to expected changes in climate in future is undertaken. Also, the possibility of watershed development integrating into a suitable mitigation strategy for the country is assessed.

皇甫川流域不同水土治理方式下土壤钾含量的变化

本文采用NaOH熔融法,原子吸收分光光度法和NH4OAc浸提,原子吸收分光光度法,分别测定了皇甫川流域五分地沟试验区不同植被治理措施下土壤的全K和速效K含量,对测定结果的分析表明：①不同治理措施下,土壤中全K含量的大小次序是：人工草地〉农田〉人工灌木〉退化草地〉次生草地〉人工林地〉百里香草原,土壤中速效K含量的大小次序是：人工林地〉百里香草原〉人工灌木〉退化草地〉农田〉次生草地〉人工草地。②不同治理方式对土壤钾含量提高的差异明显,灌草类植被对土壤钾的提高效果较好,杨树林对土壤钾的恢复效果稍差。

Listing for change? Exploring the politics of relief lists in Bangladesh after Cyclone Sidr

Ideal notions of efficient aid are challenged continuously by realities on the ground in the wake of major disasters, such as dire needs, limited resources, and opportunism. This paper demonstrates how ‘relief lists’ can be productive entry points for a systematic inquiry into the pervasive politics of disaster assistance. Through an analysis of qualitative data collected during the five years after Cyclone Sidr struck Bangladesh on 15 November 2007, it examines how relief lists featured in both physical and phantom forms and then developed beyond their transparency-making aims, becoming elevated sites of struggle for post-disaster resources. Three list processes, selected to indicate the temporal, material, and spatial dynamics of relief encounters, are assessed in depth. Although recipients of cyclone relief appreciated its value, the paper argues that list politics also stimulated structures of vulnerability, including inequality. Gradually, relief, as governed after Sidr, also served to restore the differential vulnerability of the country's coastal poor.
