| Abstract: |
| Based on the rural social and economic data during the period of 1999~2008, we establish an evaluation
system in the view of actual conditions of the study area and calculate and analyze the harmony cefficient (HC) of agri-cultural eco-economic system in the region of Guanzhong by referring to the theory of harmony coefficient of Yang Shiqi. It shows that: (1) The HC of agricultural eco economic system experiences such phases as increasing first and then de-creasing in fluctuation from 1999 ~ 2008 in the region of Guanzhong; There were a fluctuant decreasing tendency for the HC of eco-economic system, while economic subsystem and social subsystem increase except in some years. (2) The HC of agricultural eco economic system in various cities of Guanzhong shows a fluctuant increasing tendency in general, among which Weinan and Yangling develop most quickly, then Xianyang and Baoji, while Xi'an and Tongchuan were the slowest. (3) The changes of factors of agricultural eco-economic system can affect the whole system. Ecological subsys-tem has negative effect on agricultural eco- economic system, while economic subsystem shows positive effect, and social subsystem presents increase trend during fluctuations. In view of existing situation, we come up with regulation model of the HC of agricultural eco-economic system in the region of Cuanzhong. |
