| Abstract: |
| Four shrubberies such as Caragra korshinskii(C), Hippohae rhamnoides L. (H), Tamarix ramosissima(T) and Amorpha fruticosa(A) in Dingxi district were taken as the research subjects. The indicating system and approach of eco-economic efficiency evaluation are put forward in this paper based on the principle of ecological economics. Meantime, through rural social investigation and market analysis as well as shadow price approach, opportunity cost approach and replaced project approach, the eco-economic efficiency of these shrubs are calculated in the paper. The ecological efficiencies of these four shrubs from high to low is H＞T＞C＞A and the economic efficiency of the four shrubs is A＞H＞T＞C. Comprehensive analysis of the ecological efficiencies and economic efficiencies, the order is H＞A＞T＞C. According to researohes, Hippohae is optimal shrubbery for vegetation rehabilitation and is the suitable for extending in Dingxi district. |
