【摘要】：有色金属矿产开发在促进经济增长的同时,也带来诸多环境问题,在此现状下,如何评估由此造成的生态损失及系统的状态已成为研究的焦点。借助能值分析可衡量和比较不同类别、不同等级能量的真实价值这一特点,研究江西省有色金属矿产开发生态影响问题。对系统2009~2013年的能值总量、投入产出、生态损失进行核算,分析能值效率、生态效率指标变动趋势,并得出符合实际的生态补偿标准的制定依据。经过计算,2009~2013年江西省有色金属矿产开发能值自给率为0.65左右,整体变化幅度较小;能值投资率在0.23~0.31之间波动,处于较低水平;净能值产出率呈现先上升后下降的趋势;环境承载率整体较高,最低为138.01;可持续发展指数非常小,全部在0.02、0.03;生态补偿指数在62%~69%之间小幅波动。说明江西省有色金属矿产开发对当地的不可更新资源的依赖程度较高,虽然生产效率较高,但当前的生产利用活动已超出环境可承受的范围,系统不可持续发展。为改善环境2009~2013年各年应承担的生态补偿额分别为1.45×10~9元、1.49×10~9元、2.06×10~9元、2.59×10~9元、1.82×10~9元。
[Abstract]:Non-ferrous metal mineral development not only promotes economic growth, but also brings a lot of environmental problems. How to assess the resulting ecological losses and the state of the system has become the focus of research. With the aid of emergy analysis, we can measure and compare the true value of different types and different levels of energy. The ecological impact of nonferrous metal mineral development in Jiangxi Province is studied. The total emergy, input and output, ecological loss of the system from 2009 to 2013 are calculated, and the emergy efficiency is analyzed. The change trend of ecological efficiency index and the formulation basis of ecological compensation standard are obtained. The energy self-sufficiency rate of non-ferrous metal mineral development in Jiangxi Province is about 0.65 from 2009 to 2013. The whole change range is small; The emergy investment rate fluctuates between 0.23 and 0.31, which is at a low level. The net emergy output rate increased first and then decreased. The environmental load carrying rate is higher, the lowest is 138.01; The index of sustainable development is very small, all of which are 0.02n.03; The ecological compensation index fluctuated slightly between 62% and 69%, which indicated that the development of non-ferrous metals in Jiangxi Province was highly dependent on the local non-renewable resources, although the production efficiency was higher. However, current production and utilization activities are beyond the range of environmental affordability. In order to improve the environment, the amount of ecological compensation should be 1.45 脳 10 ~ 9 yuan or 1.49 脳 10 ~ (9) yuan respectively in order to improve the environment. 2.06 脳 10 ~ (9) yuan and 2.59 脳 10 ~ (9) yuan and 1.82 脳 10 ~ (9) yuan.
