| Abstract: |
| 【Objective】 A set of simple and easily worked indicators as well as its methods and models were explored for the evaluation on the coupled ecological/economic systems at small scale.【Method】 Based on the theory of ecological economic harmony and traditional indicators for ecological economic evaluation,and introducing two innovative indictors, namely emergy sustainable index (ESI) and eco footprint pressure index (EFPI),this paper assessed the coupled ecological/economic systems in eco restoration of Xiannangou Catchment by employing fuzzy comprehensive evaluation and its models.【Result】 The ecological systems of Xiannangou “agriculture cash forests orientated” model was in harmony.【Conclusion】 Xiannangou “agriculture cash forests orientated” model for eco restoration improved the ecological condition and promoted the economic development of this watershed,and facilitated the resonance between ecological protection and economic development,i.e.,the effect of coupled ecological/economic systems. |
