中文摘要钒是全球性的稀缺资源和重要战略金属,在钢铁、化工、航空航天、储能材料等领域被广泛应用。我国钒产业发展速度迅速,钒产品产量已居世界第一位,然而目前我国对钒的利用模式相对粗放,资源利用效率与回收利用程度较低。因此通过刻画钒元素在社会经济系统的物质流情况,分析造成钒资源利用效率低下的关键节点与主要因素,对保证钒资源的合理开采与钒产业的良性发展具有重要意义。本文在综述我国钒产业发展现状和物质流分析方法研究进展的基础上,开展了钒元素物质流分析和钒产业发展模式优化的研究,取得的主要成果如下: 1. 本文系统分析了我国钒资源利用产业链的现状,以及影响我国钒元素物质流的主要节点,基于现有物质流分析方法,融合我国钒资源存储特征与开采、利用模式,以及数据统计体系特点,建立了我国钒元素物质流分析模型及指标体系,并开展了实证研究,形成了2008-2010年我国社会系统钒物质流图,结果表明我国2008-2010钒资源利用率分别为27.6%、28.4%、32.2%,其中钒初级产品加工工序钒资源的流失对钒资源总体利用率影响较大。 2. 建立了基于物质流过程的钒元素价值流分析框架,定义了钒资源产出率指标及其核算方法;开展了2010年我国钒元素价值流分析及2001-2010我国钒资源产出率核算。结果表明,从钒二级产品到三级产品,价值增量较少,现阶段提钒原料中二次钒资源所占比例为13%;2010年钒资源产出率比2001年增加了3倍多,其中2005年以前呈增长趋势,2005年以后钒资源产出率则变为在波动中不断下降的趋势。 3. 基于物质流、价值流分析,以2010年为基准年,采用情景分析的方法对影响钒产业发展的要素进行分析,结果显示:在基准方案与初级方案中,未来钒元素的开采量呈逐渐下降趋势,而钒资源利用率与资源产出率分别增长,对环境的影响指数也呈现下降趋势。在中级方案及高级方案中,未来钒元素的开采量减少,但资源产出率与产业价值却远高于现在水平。总体而言,在未来钒产业的发展方向中,技术进步是关键,相关政策及经济社会条件是核心驱动力。
英文摘要Vanadium is a kind of important scarce resources and strategic metals. It is widely used in many industries, such as steel, chemicals, aerospace and energy storage materials. The vanadium industry develops rapidly in China whose production of vanadium has leaped to rank first of world. However, the utilization of vanadium resources is still in extensive way in China, with low resource utilizing efficiency and recycling ratio. As a result, the vanadium industry analysis is particularly important to ensure the rational exploitation, as well as theutilization of vanadium resources. Based on reviews of the development of vanadium industry in China, this thesis developed an substance flow analysis and optimization model of vanadium industry’s development. This thesis employs qualitative methods to develop the vanadium substance flow analysis (SFA) model for the anthropogenic vanadium metabolism in China and establishes the related indicators. The model is fit to specific storing feature and exploration mode of vanadium in China, as well as national statistical system. Applying the SFA model, this thesis elucidated the vanadium metabolism in China from 2008 to 2010. Results show that from 2008 to 2010, the overall utilization ratio of vanadium was 27.6%, 28.4%% and 32.2% respectively. Based on the SFA analysis, the analytical framework for vanadium value flow anslysis was established. The results of 2010 vanadium value flow anslysis show that the secondary vanadium raw material usage in vanadium industry were 13%. The value of the second products and the third products were almost the same. It revealed that the high value-added vanadium products was lack. Furthermore, this study identified and proposed the conception and calculation method of resource productivity. Through the calculation of resource productivity in a longer time (2001-2010), a large fluctuation of vanadium resource productivity was identified. However, there was a decreasing trend of vanadium resource productivity after 2006 which indicated that the current vanadium industry was not a healthy development model. Based on the results of substance flow analysis and value flow analysis, this thesis adopted the scenario analysis method to study the future development of vanadium industry. The baseline year was set as 2010. Several indicators were proposed to simulate the different scenarios from 2010 to 2030. In baseline scenario and primary scenario, the quantity of vanadium exploitation is decrease, but the utilization of vanadium and the output rate of vanadium resource are increase, and the environmental impact index is decrease. In intermediate scenario and advanced scenario, the quantity of vanadium exploitation is also decrease, but the output rate of vanadium resource and vanadium industrial value is much higher than present. Overall, Scenario analysis indicated that the next 20 years is a critical period for China's vanadium industry, and the technology is the source of power for vanadium industry.
