Abstract The forest resources are important contents in green GDP accounting,the soil conservation is one of its most important environmental service functions,focal point and difficult point in green GDP accounting too.Based on fully considering the characteristics of the forest ecological value,summarizes present and relevant(research) results,and accounting models of soil conservation value by forest are summarized as whole accounting model and additive accounting model.Through analyzing value accounting and including accounting results into the green GDP,it is considered that the main problems in present researches are still not consummate of soil erosion models,error of substitution accounting,the error of accounting variable data and accounting area,and replacement of benefits measure by function measure and so on.In accordance with these problems,it is suggested that strengthening the research on soil erosion,standardizing accounting indicators,separately accounting in different region,taking discounting technique and 3S technology to improve the accounting results.Furthermore,the scientific determination of green GDP,distinguishing the relation among each forests ecological function and their positions in the green GDP system should be done,so as to avoid repeat or omission in the accounting.
