Abstract:

In order to adjust and manage Shanxi Agro-ecological system more effectively, based on emergy methods, the developing regular and trend were explored in Shanxi Agro-ecological system from 1980 to 2008. Following is the conclusion: (1) Production efficiency has been improved largely. (2) The system lies in inferior position in getting economic emergy. (3) Environment loading ratio will still be high in the future. (4) Developing of Shanxi agro-ecological system depend on input of industry emergy more and more. The way to improve production efficiency of the system should be adjusting emergy input structure and improving agro-modernization equipment and technology, and transferring unnecessary labour from agriculture to other industry.
