Abstract: The experimental results show that it is practicable to plant fast-growing and high-yield poplar forest with taking advantage of forest edge effects. The reasonable structure is:8m of effective belt width and 2m?2m or 2m?3m of spacing between trees and tree rows.Significant effects are acquired from it,with an annual average tree growth of 21-33m³穐a^-1.Such a complex agroforestry operation can also be carried out within tree belts,with the economic benefits completely redeeming the initial aforestation investment.

Key words: carbon pool characteristics, soil mineralizable carbon, natural restoration, degraded Karst forest.
