This paper is a summarization on evaluation of value of artificial forest. The main contents include: (i) the difference in concepts between ecological function, ecological efficiency and ecological benefits of artificial forest; (ii) the motive and several taches of economic feedback or compensation for ecological benefit; (iii)the ecological efficiencies of artificial forest and the main correlative factors which includes the ecological efficiencies of artificial forest and the main correlation factors infecting the ecological efficiency; (iv) the basic math correlations between ecological efficiencies of artificial forest and the related factors; (v) service range of the ecological efficiencies of artificial forest; and (vi) the basic principle of measurement of ecological efficiencies of artificial forest. At the end, the basic methods of main ecological efficiencies of artificial forest are expatiated. The paper is a summarization on evaluation of value of artificial forest.
