Forest carbon sequestration(FCS)has became a new approach for reducing climate change and carbon emissions. After southern collective forest tenure reform,small- scale rural households became the main subject for FCS supply. The risk attitude of rural households can influence their willingness and decision- making about FCS supply due to new ecological compensation style and it is necessary and meaningful to analyze rural householdswillingness for FCS supply in order to identify the main FCS supply subject with decentralization forestland and improving policy aiming for carbon forest management. Through rural households survey and risk preference experiments in five case counties in Zhejiang,China. Here,we measured the risk attitude of rural households and found 72,33 and 78 rural households could be divided into riskpreference, risk- neutral and risk- averse groups,respectively. With descriptive statistics of rural householdswillingness for FCS supply and binary Logit modeling we determined how risk attitudes and other factors(e.g. individual heterogeneity,social capital and organization system) influence willingness for FCS supply. We found that FCS supply willingness of rural households with risk- averse attitudes have significantly higher willingness than the risk- preference group; larger forest land area and forest management subsidy have positive impacts on FCS supply willingness. According this,governments should pay more attention to building a carbon agency for reducing transaction costs of small-scale rural households who have risk-averse attitudes and it should encourage forestland transfer contracts and drive social capital and large- scale rural households with strong economic strength to engage in carbon forest management initiatives. Last, it is important to design carbon forest management subsidies for small- scale rural households to improve their carbon forest management activities.
