低碳经济下生态效率的困境与出路

发展低碳经济是党和国家抓住经济发展机遇和促进社会文明转型的战略选择,其实质是对生态效率的价值追求.生态效率是经济效益与环境效益的双赢,在低碳经济发展过程中既具有工具价值,又具有道德价值.生态效率不仅影响到能源效率、环境效率、资本效率和劳动生产率的发挥,还决定了经济发展的最终成败,生态效率的实现符合人类的长远利益.我国当前低碳经济下生态效率的实现还面临着思想认识偏差、公众参与缺位、技术创新瓶颈和制度供给不足等诸多困境.着力促进价值理念更新、公众参与、低碳技术创新和法律制度完善对促进生态效率的实现具有重要意义.

我国钛白粉产能迅猛扩张

根据中国涂料工业协会钛白粉行业分会24家成员企业提供的生产经营数据统计，1月～5月共生产钛白粉14．87×10^4t，比去年同期增长14．5％，其中生产金红石型钛白粉超过5×10^4t，较去年同期增长59％。同期国内进口钛白粉8．9×10^4t（绝大部分是高档专用金红石型钛白粉）；出口钛白粉6×10^4t，较去年同期增长140％。专家预测，随着国内原有的钛白粉生产企业相继加快扩产步伐，业外一些企业陆续加盟钛白粉行业，今年国内市场钛白粉表观消费量将达到85×10^4t，进口钛白粉超过20×10^4t。

我国钛白粉技术开发合作取得新进展

中国科学院网站2005年2月16日消息：中国科学院山西煤化所与江苏太白集团在钛白粉技术开发合作方面取得丰硕成果。合作开发的钛白粉表面处理新工艺对金红石钛白粉进行表面包覆处理，改善了钛白粉的白度、消色度、分散性和耐候性，能广泛应用于涂料、塑料、造纸等行业，提高了企业产品在国内外市场上的竞争力。双方建立的钛自粉后处理技术开发平台、钛白粉应用平台，开发了全国钛白粉行业第1套年产500t的后处理装置．为今后新品研发、工艺改进提供了1个放大试验的平台，有效降低了工业试生产的风险，形成一整套产业化研发生产链，为科技成果的产业化奠定了基础。     

钛白粉制备技术的研究及发展

综述了钛白粉制备的不同工艺，总结了硫酸法和氯化法在钛白粉制备中的优缺点，分析了传统硫酸法的水解过程以及氯化法中的气相氧化、内表面结疤等问题，展望了钛工业的发展趋势。结果表明，硫酸法制备钛白粉的技术日趋成熟，在实验室条件下，硫酸法中水解过程遇到的问题得以解决，但是在工业化生产时，无法做到兼顾优化水解和提高TiO₂颜料的性能，难以满足工业生产需要。氯化法被认为是当今钛白粉制取技术的发展趋势，与硫酸法相比，氯化法有巨大的环保优势，而且易于实现连续化和自动化，经济效益较好。但是氯化法对生产技术和装备材料的要求高，关键设备结构复杂，在国内的推广受到限制。国内钛白粉产业应提升现有的硫酸法工艺水平，同时对硫酸法工艺向氯化法工艺转变做出调整，还需研发新的污染物处置技术和治理方法，实现钛白粉产业的可持续发展。

基于能值分析的矿业城市工业生态效率的动态变化研究——以江西为例

矿业城市工业发展在促进经济增长的同时，也带来了诸多环境问题。在此现状下，合理评估矿业城市工业系统的环境影响及可持续发展水平是促进矿业城市工业转型的关键。借助能值分析可衡量和比较不同类别、不同等级能量的真实价值这一特点，对江西3个矿业城市工业系统2009—2018年的能值流量进行了核算，分析了能值效率、生态效率指标变动趋势。结果表明:各矿业城市的工业发展主要依赖本地环境资源，整体系统的对外开放性差；新余的能值自给率最高，萍乡次之，赣州最低，能值投资率的评价结果与之相反，萍乡和赣州二市的净能值产出率显著低于新余；3个矿业城市工业活动对环境的压力均超过了系统可承受范围，导致可持续发展水平均显著偏低，但生态效率却呈现缓慢上升的良好态势。未来3个矿业城市在充分利用本地资源的同时，应加大对外开放程度，大力发展绿色经济和循环经济，减少对环境的压力，促进矿业城市工业系统的可持续发展和生态效率的不断提升。
