Study on Stand Quality Evaluation Method of Natural Forest
摘要
Abstract
[Objective]This study aims to develop a scientific approach for evaluating the stand quality and management effectiveness of natural forests by exploring a multi-indicator comprehensive evaluation method for stand quality.[Method]Following the principles of comprehensiveness,scientific rigor,and practicality,this study identified nine evaluation criteria from two main aspects:stand structure and stand vitality.These criteria included vertical structure,horizontal structure,age structure,tree species composi-tion,stand density,stand growth,stand regeneration,large-diameter trees,and tree health.Specific evalu-ation indicators were assigned to each criterion,leading to the development of a stand quality evaluation system.A novel comprehensive evaluation index for stand quality(FQ)was constructed using the unit circle method.[Result]The validity,scientificity and accuracy of the index were demonstrated by compar-ing the stand quality of natural forests in 15 plots of 4 regions of China.The results showed that:1)The stand quality grades of natural mixed forests analyzed in the study were all≥grade II,with some forests rated as grade I;2)The quality grades of natural pure forests were grade III or grade IV;3)The stand qual-ity of natural mixed forests was significantly better than that of natural pure forests.[Conclusion]In this study,the stand quality evaluation results of the selected natural forests were consistent with the local per-ception.The evaluation was intuitive and reliable,aligning with the actual conditions and universal prin-ciples of the studied stands.It could be seen that the multi-indicator comprehensive evaluation method of stand quality proposed in this study could scientifically and fairly evaluate the quality of natural forests of different forest types in different regions of China.Moreover,it offers an important theoretical foundation and analytical tool for diagnosing stand quality issues,accurately improving stand quality,and informing forest management decisions.关键词
