| Abstract: | The cross elasticity of energy and value was put forward in this paper. It was thecomprehensive indicator that we could use evaluation structure and function of cropping sys-tem. It was strongly piont that we could transfer both efficiency of energy transformation onfarmland and economic effect of cropping system into one indicator. There was an exam-ple-a small village in the experimental areas of arid agricultural in Hebei province. |
