Abstract: By the method of emergy analysis, the development level of recycle economy in Liaoning Province was evaluated from the aspects of emergy flux, emergy nomy, ecological environment, and comprehensive index. The results showed that the development of economy in Liaoning Province was on a relatively high level. With the progress in practicing clean production, constructing ecological industry chain and recycle network, and implementing cascade use of aterial/energy flow, reuse of waste water, and comprehensive utilization of resources,etc., the energy consumption per ten thousand GDP, wastewater discharge per ten housand GDP, and solid waste discharge per ten thousand GDP were all reduced. However, the fast growth of economy was mostly supported by the consumption of a great lot of unrenewable resources, and the ability of system sustainable development was descending. To have an overall improvement in the development sustainability in Liaoning Province, great efforts should be made on increasing the emergy use efficiency, enhancing the capability of conserving and exploiting renewable resources, reasonably utilizing un-renewable resources, and upgrading the recycle use level.
Key words: Aphis gossypii, Erigonidium graminicola, Spatial pattern, Geostatistics
