摘要
运用能值理论与分析方法,从自然子系统、社会子系统、经济子系统3个侧面,系统与子系统2个层面,对广东省生态经济系统1990年以来的发展态势进行了定量分析.结果表明,广东省属于高度发展地区,系统高度依赖于反馈能值的投入,虽然污染治理卓有成效,但并未从整体上解决环境压力不断增大的矛盾,区域自身可持续发展能力低.广东省对于国际市场的信赖性日益提高,但在大量资源型产品出口和高技术产品进口的不等价交换中处于实际的亏损地位.依靠科技,提高产出品附加值,发挥落后地区自然和人力资源优势,以及发达地区的经济拉动力,是全面提高区域可持续发展能力的关键.
Based on the theories and methodologies of emergy, a quantitative analysis on the development sustainability of Guangdong Province in 1990 - 2003 was made from the aspects of environment, society, and economy at system and subsystem levels. The results showed that Guangdong Province was of developed provinces in China, and highly depended on the input of feedback emergy. Though the pollution control was fruitful, the increasing environmental loading was still not relieved on the whole, and the development sustainability was relatively low. This Province was increasingly relied on international market, and actually, under the status to the bad in exporting primary products and importing high-tech products. To improve the development sustainability of this Province, more concerns should be paid on improving the added values of products, making full use of the natural and labor resources in its underdeveloped area, and further bringing the economic superiority of its developed area into play.
