本文主要研究内容
作者吕敬文（2019）在《钢铁产业共生网络的铁/碳代谢研究》一文中研究指出：产业共生是产业生态学的重要分支,为参与者提供环境效益、经济效益和社会效益等,然而目前对产业共生网络中各参与者代谢行为的研究却很少,尤其缺少在公司层面对产业共生网络代谢行为的评估。本文以中国某钢铁集团的产业共生网络为例,采用生态网络分析(ecological network analysis)方法,通过结合铁代谢和碳代谢,从网络效能、网络控制、网络稳定性和信息分析等方面综合评估公司层面的产业共生网络中各参与者在时间动态上的代谢行为。并设置碳减排情景,评估钢铁产业共生网络在进一步实现碳减排时的代谢特性,为优化铁代谢和碳代谢行为提供建议。研究结果表明:(1)铁代谢和碳代谢的直接流的数量均随产业共生措施的完善逐渐增多,但是碳代谢始终较铁代谢有更多的直接流,从而碳代谢比铁代谢有更紧密的链接强度和关联度,说明各工艺间的碳资源交换更加密集。(2)随着网络的发展,铁资源的最大的净生产者由选矿和炼铁逐渐变为烧结和炼铁,炼铁输出的净效能逐渐减小,说明产业共生增加了烧结的铁资源输出量,缓解了炼铁供应铁资源的压力。最大的净消耗者由外环境和炼铁逐渐变为外环境和炼钢,说明炼钢在产业共生措施的完善中获得了发展。在碳代谢中,焦化和炼铁是最大净生产者,但焦化的贡献逐渐小于炼铁。最大的净消耗者由外环境和炼铁变为外环境和焦化,外环境净输入效能不断增多,体现在生铁和轧钢产量的增加。另外产业共生增加了焦化的碳资源的供应量,缓解了炼铁供应碳资源的压力。废物管理接收的净效能均逐渐降低,体现出产业共生在减少废物排放的优势。共生是铁代谢主要的关系类型,而在碳代谢中利用关系更为突出。两元素代谢均达到共生状态。(3)在产业共生网络发展初期,外环境对铁代谢和碳代谢的控制度最高,分别达到54%和58%,说明生产主要依赖于外环境提供的物质和能源。炼钢和轧制的加入分流了铁代谢35%的控制度。外环境对碳资源的控制度的下降转变为炼铁控制度的上升,炼钢和轧制并未表现出对碳代谢的主要控制力。产业共生的发展逐渐降低铁代谢对外环境的依赖,炼铁和炼钢工序的控制度呈上升趋势。但是碳代谢的控制度分配变化不大,说明产业共生的实施对铁资源分配的影响更大。总体上一个工序的控制度与流经该工序的总流量成正比,但是控制度的变化对铁资源的分布更敏感。(4)该钢铁产业共生网络等级结构由生产者(外环境)、初级消费者(选矿、焦化、烧结、球团)、次级消费者(炼铁)、三级消费者(炼钢)、终极消费者(轧制)和分解者(废物管理)等六个营养等级组成。在产业共生网络的发展中,铁代谢的结构组成较均匀,但是外环境的贡献有所降低,而选矿的贡献有所增加。碳代谢结构逐渐发展成三角形,虽然符合稳定的生态系统特征,但是碳资源主要分布在结构的底部,代谢效率低。(5)虽然铁代谢和碳代谢的发展能力呈显著正相关,但是碳代谢较铁代谢增长的更快。发展能力的增长主要依赖于代谢网络规模的扩张,而不是多样性的变化。在效率与抵抗力的平衡中,铁代谢处于效率主导,而碳代谢处于抵抗力主导。说明在强调生产钢铁产品的前提下,铁资源的利用更为高效。(6)根据情景分析,以第四阶段为基准的情景不能实现2020和2030年的减排目标。推广新技术可以实现大幅度的碳减排,但只能达到2020年的碳减排要求,不能实现2030年的碳减排要求。在此基础上调整能源结构,2030年的减排目标可以实现。废钢-电炉的减排效益较少,主要是由于钢产量占比不足。单独实行调整能源结构和增加废钢-电炉均不能满足减排目标。由于各减排情景中铁代谢的上升性大幅增加,超过了碳代谢的上升性,因此,在实现碳减排时要求大幅提升铁代谢发展程度,提升代谢效率。而碳代谢的上升性占发展能力的比值不断下降,反映出碳代谢中冗余较上升性增长的更快,因此各工艺间碳资源的分布应更加均匀。
