Abstract: This paper deals with research on how to initially handle the remainder of forest cleaning, afforesting and thinning into the form that can be convenient to be carried in forest and submit the raw material to forest plantation by scientific rational vehicle for co-generation comprehensive development.Preparing to construct serial dynamoelectric installations in forest plantation and the power generated by finite generator sets in forest plantation will be connected to national electric network through attached machine and corollary network equipment.The power sold to nation makes profit and the additional thermal energy is provided to forest plantation, thus entirely solve the problem how to utilize the resource of cleaning, afforesting and thinning efficiently and the problem about road and cost for transportation of resource, and increase the economic benefit of utilizing the resource of cleaning, afforesting and thinning.Put forward to promote cleaning and thinning with the profit of co-generation comprehensive development, push on cleaning and promote natural forest preservation project by economic leverage, expedite recovering national forest resources by the benefit of co-generation comprehensive development and provide a way to make profit for natural forest preservation area.

Key words: co-generation, cleaning and afforesting, remainder of thinning
