Abstract: Based on the verification data of natural forest survey in Yunnan province in 2023, national level public welfare forest in 2021, and provincial level public welfare forest optimization data in 2023, statistical analysis and evaluation were conducted on the land type composition, spatial distribution, classified management, protection status, and current status of forestry ecological base in the province. Based on the perspective of integrating natural forest protection and public welfare forest management, the problems in the construction of Yunnan province's eco-forest was pointed out from the aspects of policy and regulatory standard system, ecological forest basic information, classification management, and ecological forest value realization. The overall idea for the construction of Yunnan province's eco-forest was proposed, such as establishing a standard system and constructing a complete ecological forest protection and restoration policy and regulatory standard system; carring out special investigations, annual dynamic monitoring, and a comprehensive survey for 10 years to support the ecological foundation of forestry in the province; multi planning and overall planning, constructing a new pattern of forestry ecological space; further exploring the mechanism for realizing the value of ecological products, and assisting in the high-quality development of the forestry and grass industry.
