内蒙古煤炭行业的清洁生产及其相关技术的研究

本文在对内蒙古自治区煤炭行业发展现状分析的基础上,借鉴国内外煤炭行业及其企业推行清洁生产的实践经验,以循环经济"3R"原则,即减量化、再使用、资源化为指导,针对煤炭行业的污染特性,对适合本地区煤炭行业实施清洁生产的主要内容和相关技术进行了研究.     

在市场经济条件下推进环境保护服务业发展

长期以来，我国第一产业，第二产业在经济中的比重相对偏高，而服务业却比较落后和幼稚，在21世纪的经济中，服务业的落后才真正意味着经济的落后，随着市场经济的发展，特别是我国加入WTO后，与国际接轨的步伐加快，给服务业尤其是环保服务业的发展提供了机遇，并开辟了广阔的空间，本文分析了我国环保市场及其管理的现状，强调了环保服务业的发展是市场经济的客观要求，明确了现阶段我国环保服务业的基本工作范围，提出了推进环保服务业发展的思路及建议。

东湖开发区产业布局对环境的影响研究

武汉东湖高新技术开发区是首批国家级高新技术产业开发区之一,产业基础好,发展条件佳.近十年是其经济和社会发展的重要时期,是进行经济结构战略性调整和改革开放的重要时期,也是减轻环境污染和遏制生态恶化趋势的重要时期.但由于开发区建设初期注重经济建设,忽视环境保护,使环境问题日趋严峻.因而,紧紧抓住新世纪的历史机遇,下大力气解决开发区突出的环境问题,调整产业结构,合理产业布局,制定切实可行的生态规划和环保措施迫在眉睫,以期实现长期快速增长,持续、均衡发展.     

环保产业 亟待整顿

环保产业存在政策不完善、结构不合理、市场混乱、技术含量不高、企业规模效益低下等诸多问题。环保产业健康发展应结合市场经济体制改革,制定和完善产业政策,合理布局产业结构,培育和调控环保产业市场,提高环保产业技术水平和企业规模经济效益,以利于健康、协调、持续和稳定发展。     

辽东半岛自然资源的优势及其在农业中的利用

辽东半岛是东北东部山地的南延部分,属于暖温带落叶阔叶林景观。由于受到海洋的影响,气候比我国同纬地区温和、湿润,为太区农业、林业及果蚕业的发展提供了有利条件,同时本区海岸曲折,港湾众多,富海上交通和渔业之利。在东北地区,本区是一个自然环境较优越,自然资源较丰富的区域。本文主要阐述辽东半岛自然地理的基本特征和自然资源的优势,并对其利用方向作了初步探讨。     

Application of cleaner production technology in chemical industry: a near zero emission

The main objective of this study is to investigate and evaluate opportunities for implementation of pollution prevention and waste minimization in a chemical industrial company producing poly sulfonated naphthalene formaldehyde which is used as a super plasticizer for concrete. Environmental problems encountered were mainly the highly polluted wastewater and a semi-solid cake containing considerable amount of the final product. Possible modules for remedial measures and their cost estimation were investigated. The proposed remedial modules included recycling of retained water discharge in filter press, recycling of washing water of reaction vessels (reactors), closed circuit cooling system for high-pressure pump, good housekeeping through control of leakage of raw material, products and water and finally utilization of retained residual product from the solid waste. The implemented pollution control measures proved to be cost effective and have short payback periods. Also, minimization of the hydraulic and organic loads in the final effluent was achieved.     

煤炭工业发展与土地资源管理

土地资源是一种不可再生资源，一旦破坏就很难再恢复，新的《土地管理法》对土地的保护提出了更为严格的措施；煤炭工业是土地破坏的大户，新的《土地管理法》的颁布加重了煤炭企业破坏土地的赔偿负担，煤炭工业的发展面临更为严峻的形势。在当前情况下，探讨煤炭工业发展与土地资源管理之间的二元关系对于实现煤炭工业可持续发展具有十分现实的意义。

Relationship between urban eco-environment and competitiveness with the background of globalization: Statistical explanation based on industry type newly classified with environment demand and environment pressure

Within the global urban system, the statistical relationship between urban eco-environment(UE) and urban competitiveness(UC)(RUEC) is researched. Data showed that there is a statistically inverted-U relationship between UE and UC. Eco-environmental factor is put into the classification of industries, and gets six industrial types by two indexes viz. industries‘ eco-environmental demand and pressure. The statistical results showed that there is a strong relationship, for new industdal classification, between the changes of industrial structure and evolvement of UE. The drive mechanism of the evolvement of urban eco-environment, with human demand and global work division was analyzed. The conclusion is that the development stratege, industrial policies of cities, and environmental policies fo cities must be fit with their ranks among the global urban system. At the era of globalization, so far as the environmental policies, their rationality could not be assessed with the level of strictness, but it can enhance cities‘ competitiveness when they are fit with cities‘ capabilities to attract and control some sections of the industry‘s value-chain. None but these kinds of environmental DOlicies can probably enhance the UC.
