Background--Livelihood activities of workers households in key state-owned forest regions are closely related to forests. Due to the existence of the resource curse, families with high dependence on forest resources are often still poor in this area. ⑵ Methods--Based on 2198 survey data, according to absolute forest income and relative forest income, the types of livelihood strategies of worker households are divided. Based on the sustainable livelihood analysis framework, the capital evaluation index system of worker household livelihood in key state-owned forest regions is constructed. Logistic regression model is used to analyze the key factors affecting the transformation of livelihood strategies of workers households. ⑶ Results--The forestry-related livelihood strategies of workers household in key state-owned forest regions can be divided into four types, namely, forestry advantage type, forestry supplement type, forestry dependence type and livelihood diversification type, accounting for 28. 8%, 7. 89%, 21. 89 % and 41. 34%, respectively. From the perspective of income level, the family income level of forestry-dependent workers is the worst, the income level of forestry supplementary workers is the highest. From the perspective of the level of livelihood capital, forestry complementary worker household have the highest natural capital, material capital, financial capital and social capital. In terms of forestry dependent type, worker households with higher natural capital, physical capital, human capital and financial capital tend to choose forestry supplementary livelihood strategy, and only those with higher human capital tend to choose forestry advantage livelihood strategy. Taking livelihood diversification as a reference, worker households with higher levels of natural capital and human capital are more likely to transform into forestry complementary type, while worker households with higher levels of physical capital, financial capital, human capital and social capital are more likely to transform into forestry dominant type. ⑷ Conclusions and Discussions--The income and livelihood capital levels of different livelihood strategies show a decreasing trend with the increase of forest dependence. The transformation of livelihood strategies of worker household is affected by their livelihood capital, family demographic characteristics and residence characteristics. The transformation of worker households from forestry dependence to forestry supplement needs to improve their livelihood capital levels and optimize their structure. In key state-owned forest areas, when worker households can obtain the capital and material information needed for production, make full use of natural resources such as forest land to develop production and operation activities, improve their employment skills and management skills, enrich and make good use of social network relations, and actively seek non-forest employment channels, the income of worker households obtained by using forest is improved and the degree of forest dependence is reduced, so as to realize the transformation of their livelihood strategy types and the sustainable development of livelihood. It is therefore recommended that: ①Workers can make full use of forest land resources, rich forestry employment content. ②Governments are expected to build a platform to promote the flow of physical capital and make physical capital play a better role. ③Companies should provide diversified vocational and technical training to improve the employment skills and business skills of workers. ④It is necessary for governments to encourage worker households to engage in non-forest employment and promote diversified livelihood development.
