摘要
Forests create three major benefits, i.e. economic, ecological and social benefits. Evaluation onforest ecological benefits is an important issue to study nowadays, which can provide the scientific basis forreasonable allocation of resources and realization of forestry compensation. This paper is focused on theconception of forest ecological benefits, the current research on evaluation of forest ecological benefits athome and abroad, and research methods adopted and theoretical basis with the following 7 aspects involved:water head protection, soil and water conservation, wind prevention and sand fixing, carbon fixing and oxygenproduction, atmosphere purification, forest recreation and biodiversity conservation. Problems existing incurrent studies are also presented, such as rationality of replacement, compatibility of the outcomes, repetitionof calculation, comprehensiveness of evaluation and affection of subjective factors, and so on. In the end,suggestions for future studies on evaluation of forest ecological benefits are offered.

Evaluation on forest ecological benefits is an important issue to study nowadays, which can provide the scientific basis for reasonable allocation of resources and realization of forestry compensation. This paper is focused on the conception of forest ecological benefits, the current research on evaluation of forest ecological benefits at home and abroad, and research methods adopted and theoretical basis with the following 7 aspects involved： water head protection, soil and water conservation, wind prevention and sand fixing, carbon fixing and oxygen production, atmosphere purification, forest recreation and biodiversity conservation. Problems existing in current studies are also presented, such as rationality of replacement, compatibility of the outcomes, repetition of calculation, comprehensiveness of evaluation and affection of subjective factors, and so on.
