[Integrative study of Guangdong ecological-economic system based on emergy analysis].
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.
