Abstract :
At present, the urbanization in Beijing is developing fast, and its accompanying rapid accumulation pattern of urban infrastructure stock is undoubtedly of great significance to the realization of Beijing's infrastructure construction and urbanization coordinated development. This paper analyzes the time series of changes in 8 types of infrastructure stock and 10 types of infrastructure materials in Beijing through the stock accounting model. The decoupling relationship between the level of urbanization in Beijing and the infrastructure stock is analyzed through the decoupling model. Its purpose is to achieve social and economic development while achieving the optimal scale of infrastructure stock construction, thereby promoting the progress of Beijing's new urban development. The results show that: (1) Beijing's infrastructure stock was on an upward trend from 1949 to 2018. In 2018, the total infrastructure stock expanded to 1,384 times that of 1949, reaching 3,342.036 million tons. It has experienced a process of slow growth from 1949 to 1975, rapid growth from 1976 to 2008, and steady growth from 2009 to 2018. (2) From 1949 to 2018, in terms of building types, Beijing has the largest housing stocks, followed by the road stocks, the pipeline stocks and the track stocks. In terms of material types, gravel, cement, bricks, and steel account for about 99% of the infrastructure material stock in Beijing. (3) The state has reached weak decoupling between the level of urbanization in Beijing and the stock of roads and track, and is moving from "weak decoupling" to finally achieving "strong decoupling", while the state between the level of urbanization and housing stocks and pipeline stocks has not yet reached decoupling. The state between the level of urbanization and the stock of various infrastructure materials has not yet reached a state of decoupling, and most of them are extended decoupling, which puts great pressure on Beijing's resources and environment.

Abstract :
Dematerialization is a phenomenon in which resource consumption and pollutant discharge decrease during economic development. In order to explore the optimal paths of Beijing's dematerialization, this study combines material flow analysis method and the Tapio decoupling model to construct a city dematerialization evaluation model, and establishes a system dynamics model to simulate the comprehensive dematerialization levels and the dematerialization levels of eight materials under four scenarios. The results show that the key factors affecting the dematerialization levels of resource and discharge end were non-metals consumption and CO2 emissions respectively. During 2016-2030, Beijing would achieve weak decoupling state under four scenarios, but the degree of dematerialization would be different. For the comprehensive dematerialization level, during 2017-2024, an industrial restructuring (IR) scenario, which would strengthen R&D investment and optimize the industrial structure, would be the optimal choice. During 2025-2030, an environmental governance (EG) scenario, which means increasing the investment in pollution control, would bring about the best dematerialization level. There would be differences in the optimal dematerialization paths for eight materials. For example, economic sustainable degrowth (ESD) and EG scenarios would be the optimal paths for dematerialization of atmospheric pollutants in the period 2017-2021 and 2022-2030, respectively.

Abstract :
基于物质流分析方法中的自下而上法分析1992—2016年北京市房屋和基础设施两大类建筑的6类主要建筑的10种建筑物质存量和流量.结果表明:2016年,北京市6类主要建筑中的物质总存量扩大到1992年的4.91倍,达2001.91百万t;其物质输入量与2014年和2015年相比有下降趋势,为10852.07万t;其物质输出量仍有上升趋势,为3806.59万t;北京市道路物质存量呈现高输入、高输出的特征,房屋物质存量呈现高输入、缓输出的特点.房屋的废弃物具有较长的滞后期,且数量庞大.按现有房屋预期寿命不变,估算2017—2050年北京市房屋废弃物量,北京市将在2040年迎来房屋废弃物高峰期,届时废弃物量达5445.50万t.

Abstract :
Aiming at the contradiction between the economy and ecological environment in the recycling process of waste paper, using the material flow as a carrier to construct the value flow of waste paper recycling system. The connotation of ecological cost of waste paper recycling system was defined, and its ecological cost accounting model was established. Taking the minimum ecological cost of waste paper recycling system as the objective function, the optimal design was based on the constraint condition of economic benefits, manufacturing process conditions, national policy and industrial standards. The results showed that the ecological cost was reduced to 1385.69 yuan per ton after optimization, which was down by 456.8 yuan per ton compared with that before optimization, and the decrease was 24.79%. At the same time, the economic benefit increased to 1326.95 yuan per ton, 13.51% higher than that before the optimization. It was suggested that the enterprises of waste paper recycling ought to develope intensively in the future, increase the amount of larger-scale packing plant; properly control the price of waste paper, avoid the high price of waste paper. A moderate economic compensation to waste paper recycling enterprise from government, would be benefit to both economy and ecological environment. © 2018, China National Pulp and Paper Research Institute(CNPPRI).

Abstract :
针对废纸回收利用过程中经济与生态环境之间的矛盾,以物质流为载体,构建废纸回收利用体系的价值流。在此基础上,界定了废纸回收利用体系生态成本的内涵,并建立其生态成本核算模型。以废纸回收利用体系生态成本最小为目标函数,以经济效益、生产工艺条件、国家政策和行业标准为约束条件,进行优化设计。结果表明,优化后生态成本为1385.69元/t,与优化前相比下降了456.8元/t,降幅达24.79%;经济效益增加到1326.95元/t,比优化前提高了13.51%。建议加强废纸回收打包企业集约化发展,提高大型打包厂比例;适当控制废纸价格,避免废纸价格过高;国家对废纸回收利用企业进行适度经济补偿,将有助于废纸回收利...

Abstract :
协调资源环境与经济之间的关系是解决京津冀环境经济矛盾问题的前提,是推动京津冀协同发展的重要环节.基于物质流分析框架建立了评价指标体系,对1992-2015年京津冀地区资源环境经济协调发展的演化趋势进行评价分析.结果表明,北京市资源环境经济协调发展的演化趋势最优;天津市资源系统发展指数可能由于滨海新区的规划建设而未出现明显回升,是影响天津资源环境经济协调发展的主要因素;河北省资源环境经济协调发展的演化趋势出现较明显回升.在京津冀协同发展的时代背景下,各地要准确定位、加强合作,实现京津冀地区资源环境经济协调发展.

Abstract :
推动京津冀协同发展是重大国家战略,实现生态质量协调发展是京津冀协同发展的要求之一。基于物质流分析框架,建立生态质量评价指标体系,并建立协调度模型,对1992—2015年京津冀生态质量协调发展的演化趋势进行评价分析。结果表明:京津冀资源投入方面和废物排放方面生态质量协调发展度的演化趋势基本保持一致,都分为上升期、下降期和上升期三个阶段。2014年和2015年,京津冀资源投入方面生态质量协调发展度虽出现较明显的回升,但2012—2015年,废物排放方面生态质量协调发展度上升幅度仅为0.02,要实现京津冀生态质量协调发展任重而道远。津冀两地的生态质量是影响三地生态质量协调发展的主要因素,各地要准确定...
