南水北调中线工程对汉江中下游工业发展的影响

南水北调中线工程计划从丹江口水库向我国北方每年调水１４５亿ｍ＾３,汉江丹江口以下地区的水资源量将随之相应减少。汉江中下游地区是湖北省盐化工、机械、石油、食品、化肥、电力的重要生产地区,是湖北省的汽车工业走廊,其经济在湖北省占有举足轻重的地位。由于经济的迅速发展,下世纪工农业生产和人民生活对水资源的需求将从现在的１４０亿ｍ＾３增加到２５０亿ｍ＾３以上,需水量将达到水资源量的５８％,潜伏着严重的水资源

Glocalization of COVID-19 responses and management of the pandemic in Africa

ABSTRACT

The study explores how glocalization of COVID-19 responses affects the management of the pandemic in Africa. Using data from 20 selected African countries, the study found that the reliance on local medicines alongside other salient global initiatives for containment of COVID-19 is effective in managing the pandemic in Africa. It concluded that despite the high vulnerabilities of African countries to COVID-19, the glocal approach has yielded positive outcomes by increasing the number of patients that recover from COVID-19 and scaling down the fatalities compared with the other regions.     

乡镇工业企业发展与环境,资源协调问题初探

我国乡镇工业企业的发展与环境、资源的协调问题已经成为我国发展与环境、资源关系方面的大问题。实行工农相对分离,组建乡村工业区,是提高乡镇工业企业素质、效益,强化乡镇工业企业优化组合、规模经营的有效途径;是保护环境,实现资源有效利用的基础工作之一;是提高农业劳动生产率,实现农业规模经营的基础工作之一。     

Utilization of red mud as catalyst in conversion of waste oil and waste plastics to fuel

The aim of this study was to investigate the possibilities of using a by-product (red mud) from alumina production as a catalyst for recovery of waste. The conversion of waste mineral oil (WMO) and waste mineral oil/municipal waste plastic (WMO/MWP) blends over red mud (RM), a commercial hydrocracking catalyst (silica–alumina), and a commercial hydrotreating catalyst (Ni–Mo/alumina) to fuel has been studied. The effect of the catalyst and the temperature on the product distribution (gas, liquid, and wax) and the properties of liquid products were investigated. In the case of hydrotreatment of WMO, the liquids obtained over RM at both 400° and 425°C had larger amounts of low-boiling hydrocarbons than that of thermal or catalytic treatment with hydrotreating catalyst. Gas chromatography and nuclear magnetic resonance analysis of the liquid products showed that RM had hydrogenation and cracking activity in hydrotreatment of WMO. In coprocessing of WMO with municipal waste plastics, temperature had an important effect as well as the amount of MWP in the blend and the catalyst type. The hydrocracking at 400°C produced no liquid product. In hydrocracking at 425°C, the product distribution varied with catalyst type and MWP amount. The commercial hydrocracking catalyst had more cracking ability in the conversion of WMO/MWP to liquid and gas fuel than RM. In the case of hydrocracking over RM, the largest amount of liquid having satisfactory quality was obtained only from the blend containing 20% MWP.

Motives as Predictors of the Public's Attitudes Toward Solid Waste Issues

/ Surveys focusing on solid-waste-related issues, conducted over a period of several years, provided data from independent samples of residents of a Midwestern, USA, community. The collection of these data yielded useful information about the relationship between residents' recycling motives and their attitudes toward solid waste management in light of several changes in the solid waste infrastructure of the community over that time. The initial survey assessed baseline beliefs and attitudes, while later surveys were conducted after the implementation of a community educational program and a curbside recycling program. The findings indicated that for recyclers and nonrecyclers, different motives predicted endorsement of solid waste programs and policies. Although a similar percentage of recyclers and nonrecyclers were in support of various proposed programs and policies, concern for the environment was found to be positively related to nonrecyclers' support of proposed programs, particularly before these programs were implemented. Prior to program implementation, motives other than environmental altruism were found to be related to recyclers' support of the programs. Additional findings support the idea that educational programs and increased accessibility to recycling opportunities affect the relationship between people's attitudes toward solid waste management and their recycling motives.

美国离境外包经济动向的环境影响

最近美国离境外包经济发展很快，并引发继第一次产业革命（即工业革命）和第二次产业革命（即服务业超过制造业）之后的第三次产业革命，进而美国大批制造业向国外转移。这对我国承接制造业的产业转移是重大机遇，但同时也会遇到污染、能源转移的问题。建议我国抓住机遇，保持和发挥人力资源优势，迅速发展制造业，同时积极应对环境影响，分类管理，严格执法。     

秦皇岛市50年气候变化与可持续发展战略研究

秦皇岛市50年来气候变暖变干，年平均气温提高2．3℃，≥10℃年积温增加11．4％，无霜期延长22天，但年平均降水量却减少12．6％。这对农业和工业的影响弊大于利，对旅游业的影响则有利有弊。为此应趋利避害，加强水资源的开源节流，发展节水经济和循环经济，发展休闲度假旅游，延长旺季。
