Validity Evaluation On Recycle Economy Based On Material Flow

With the development of industrialization, we have made enormous economicbenefits, while also greatly damaged the ecological environment which lead to a seriesof questions, such as ecological imbalance, environmental degradation, depletion ofResources and Environment. Implementation of the development of circular economyhas become the consensus of domestic and foreign academic circles. Researchers ofacademia uses material flow analysis method to analyze the circular economy, and hasaccumulated a certain amount theoretical basis and practical experience on level ofdevelopment of measuring the circular economy, resource consumption,environmentally friendly, which provides an important reference on the theories andmethods that We use material flow analysis method to evaluate regional recyclingeconomy in Gansu Province. This paper systematically studies the cycle economicdevelopment of Gansu Province from2006to2007which takes Gansu Province asthe research object and is based on Gansu Province as well as domesticYearbook-based data and comprehensively uses qualitative and quantitativemethods,.This paper establishes a series of indicators on the basis of describing thetheories of material flow and building the material flow analysis framework. Thefollowing conclusions are made after correlation analysis:1)2006to2010. Theeconomic development in Gansu Province is rapid, per capita GDP or GDP growthgrows rapidly and growth rate of average GDP is11.16%. Economic grows faster, butGDP in absolute terms is in the backward position nationwide.2) The ecologicalenvironment of Gansu Province has changed. TMR,TRO, TMC, but the growth rate isless than the GDP growth rate, indicating that the economic development of GansuProvince began a good sign.3) The economic development of Gansu Provinceincreasingly demands energy, and consumes more and more energy, and energyresources are the main producer of carbon dioxide. The greater the energy isconsumed, the more carbon dioxide is made, and the more seriously environmentalpollution is caused by Energy extraction. The implicit flow caused by energyextraction pollutes the environment. On the region hidden stream, hidden streamcaused by energy extraction is more than50%. Wastewater discharge damages seriously the ecological environment in Gansu Province. The absolute value ofindustrial wastewater and domestic wastewater is larger, and industrial waste water ison top of150million tons and domestic wastewater is about300million tons. Inaddition, the efficiency of substance utilization in Gansu Province is low.4) Theindustrial structure in Gansu Province is irrational. The second industry, especially theheavy industry occupy a high proportion of the three major industries, and thedevelopment of agriculture and tertiary industry is lower.
