【摘要】：伴随经济的快速发展资源短缺和环境污染问题得到全球各国的关注。循环经济作为一种可持续的经济发展方式,以“3R”为发展原则,在实现资源节约的同时,减少了对环境的污染。我国循环经济发展虽起步较晚,但已取得了突出的成就。循环经济评价指标体系是一种定量评估区域循环经济发展的有效手段,我国已在国家级、省级、市县级等层面做过相关研究;然而在指标体系的全面性、科学性及可操作性等方面,仍需要不断完善及改进。本研究在国内外研究的基础上,利用物质流分析方法,结合全国《循环经济发展评价指标体系(2017年版)》构建了区域循环经济评价指标体系。指标体系根据物质流分析方法的特点,分为物质输入层、物质消耗层、物质输出层和物质利用效率层4个层次,包含24个指标;力争在物质输入到输出的全过程内实现对物质的全面分析。其中,在指标性质栏中,将各项指标划分为资源指标及环境安全指标;环境安全指标表征循环经济在资源及环境安全中的作用。本研究以山东省为研究对象,对山东省2005-2014年间循环经济指标进行核算分析;并参照日本环境省物质流分析方法,对山东省2005年、2009年、2014年进行了物质流全景分析。通过对山东省2005年、2009年及2014年物质流的全景分析,可以得出山东省的物质投入量在逐年增加,在固体废弃物的综合利用方面取得了一定的成果。通过对山东省2005-2014年循环经济指标的核算,发现:(1)在物质输入方面,2005-2014年山东省直接物质投入量和物质需求总量均呈现上升趋势,这主要是由于能源进口和金属矿物生投入量的增长。(2)在物质消耗方面,山东省物质消耗总量呈现上升趋势,与物质投入趋势基本保持一致。(3)在物质输出方面,2005-2014年山东省物质输出总量保持增长态势,固体废物排放量、工业废水排放量等呈现利好态势,此外能源出口、废水中COD和氨氮排放增长是促使物质输出总量增长的重要因素。(4)在物质利用效率方面,2005-2014年,山东省资源产出率呈现逐年上升趋势,由85.75元/吨增长到97.69元/吨,年均增幅1.55%;水资源产出率由88.45元/吨增加到103.30元/吨,年均增长1.78%;但建筑用地产出率总体呈现下降趋势,年均跌幅为7.89%,人均物质消耗量与人均废弃物排放量呈增长态势,物质消耗的增长速度、废弃物排放的增长速度快于人口增长的速度;总体而言,山东省物质消耗速率快于经济增长速率,资源投入及资源消耗仍较大;并且各环境安全类指标虽有所改善,但仍存在较为严重的环境安全问题;故资源安全和环境安全仍是经济发展中关注的重点。
[Abstract]:With the rapid development of the economy, the shortage of resources and environmental pollution have attracted the attention of all countries. As a sustainable economic development mode, circular economy takes "3R" as the principle of development, and reduces the pollution of the environment while realizing the conservation of resources. Although the development of China's circular economy has started relatively late, it has made outstanding achievements. The evaluation index system of circular economy is an effective means for the development of regional circular economy a quantitative assessment, China has in the national, provincial, city and county levels have done related research; however, the comprehensive index system of scientific and operational aspects, still need continuous improvement and improvement. Based on the research at home and abroad, combined with the national evaluation index system of circular economy development (2017 Edition), the evaluation index system of regional circular economy is constructed based on the research at home and abroad. According to the characteristics of material flow analysis method, index system is divided into 4 levels, material input layer, material consumption level, material output layer and material utilization efficiency level, including 24 indicators, and strive to achieve a comprehensive analysis of matter in the whole process of material input and output. Among them, indicators are divided into resource indicators and environmental safety indicators, and environmental safety indicators represent the role of circular economy in resources and environmental safety. This study takes Shandong Province as the research object, calculates and analyzes the index of circular economy in Shandong Province in the past 2005-2014 years, and analyzes the panoramic analysis of material flow in Shandong Province in 2005, 2009 and 2014, referring to the material flow analysis method of Japan's Ministry of environment. Through panoramic analysis of material flow in Shandong Province in 2005, 2009 and 2014, it can be concluded that the material input of Shandong is increasing year by year, and some achievements have been made in the comprehensive utilization of solid waste. Based on the accounting index of circular economy in Shandong province for 2005-2014 years, it was found that: (1) in terms of material input, the total material input and total material demand in Shandong province showed an upward trend in 2005-2014 years, which is mainly due to the increase of energy import and the input of metal minerals. (2) in terms of material consumption, the total amount of material consumption in Shandong showed an upward trend, which was basically consistent with the trend of material input. (3) in the material output, 2005-2014 in Shandong Province, material output to maintain growth, solid waste emissions and industrial wastewater emissions and other positive trend, in addition, the export of energy in wastewater COD and ammonia emissions growth is an important factor to promote the growth of the total output of material. (4) in the material utilization efficiency, 2005-2014 years, Shandong province resources output rate is rising year by year, from 85.75 yuan / ton rose to 97.69 yuan / ton, an increase of 1.55%; water resource output rate by 88.45 yuan / ton to 103.30 yuan / ton, the average annual growth rate of 1.78%; but the construction land output rate the overall downward trend, the average annual decline of 7.89%, the per capita material consumption and waste emissions per capita emissions growth, growth rate, waste material consumption growth faster than the rate of population growth in Shandong province; overall, material consumption rate faster than the rate of economic growth, resources and resource consumption is still large; and the environmental safety index has been improved, but there are still serious environmental safety problems; the key resources and environment safety is still in the economic development of attention.
