Abstract: With the increasing activities in forest resource asset evaluation for investment purpose, a lot of related theoretical problems need to be solved urgently. Based on the problem research in value type, evaluation method, and evaluation parameters, it concluded that: the selection of value types,which contained the type of market value and the type of investment value by taking into account of market practical limitations, depends on commission"s interest demands; the choice of evaluation method should be adapted into evaluation purposes and the value type. When the type of market value was selected, market comparison approach should be the first choice for the assessment. When the type of investment value was selected, the income approach should be the first choice while the client was the financial investor, and the assessment formula should be the first choice while the client was a strategic investor. The evaluation parameters should be consistent with the assessment methods. The key parameter of market law is comparable reference object, the key parameter adopted by income approach is ROI, and the key parameter of assessment formula is revenue share rate . Forest resource asset evaluation for investment purpose should consider the impact of forest cutting quotas and other related policies.
