摘要
本文运用物质流分析(MFA)和IPAT分析方法,对海南省环境经济系统1990-2008年间的物质输入与输出进行研究,并与同期广东省数据进行对比分析。结果表明:1990-2008年间,海南省环境经济系统直接物质输入呈上升趋势,1990-2007年间增长速度平缓,年均增长6.88%,而区域过程排放呈下降趋势,年均降低0.95%;19年间,除个别年份外,海南省物质输入强度、输出强度及物质输入效率均低于同期广东省水平,1994年以前,海南省物质输出效率明显低于同期广东省水平,1995年开始逐渐接近同期广东省水平。对以上结果进行分析,可揭示我国唯一的热带岛屿省份———海南省的物质流特征与演变规律,能够为区域循环经济与可持续发展提供科学决策,促进海南生态省、新型工业省和国际旅游岛的建设。
Material flow analysis（MFA） and IPAT method are employed to probe into the natural material input and material output of the Hainan environmental-economic system during the period from 1990 to 2008,with a comparison of those of Guangdong Province.The results show that the direct material input（DMI） of Hainan Province has been increasing,with the annual growth of 6.88% during 1990-2008,while the regional processed output（RPO） declining with the annual rate of 0.95%.During the concerned 19 years,except for a few years,the intensities of DMI,RPO,and the efficiency of DMI are lower than those of Guangdong province.The output efficiency of Hainan is notably less than that before 1994 and approaching that of Guangdong after 1995.Therefore,the characteristics of materiall flow and evolution mechanism of Hainan,as the unique tropical island-type province in China;have been revealed,which could serve the regional circular economiy and sustainable development of Hainan,thus stimulating the construction of a ecological and industrial province and an international tourist resort.
