Site Quality Evaluation Of Mixed Coniferous-Broadleaved Forest In Tianmu Mountain Based On SI_CSC_ISPA Model

Site quality evaluation of forest is a basic work of forest management,is the research on basic theory of forest management,and production potential of forest scientific judgment and prediction is the basis for the formulation of scientific and rational scheme of forest management.Quality evaluation of mixed forest of mixed coniferous and broad leaved forest for zhejiang province’s forest resources protection and sustainable management to provide important scientific.This study according to the Tianmu Mountain conifer and broadleaf mixed cross forest effects and applications,analysis of the connotation of site quality,based on the Tianmu Mountain coniferous forest plots data,has put forward The quality evaluation index system of mixed forest of mixed forest with production potential and carbon sink potential,The establishment of SI_CSC_ISPA evaluation model is to establish a scientific and comprehensive evaluation system of mixed forest and mixed forest.Compared with the traditional evaluation index,the mixed forest land quality evaluation of the mixed forest of the stand index and the potential index of carbon sequestration,the evaluation index is more in line with the characteristics of the mixed forest.(1)Site index method that based on tree height curve combined with analysis theory,constructing the evaluation system which has stand production capacity and stand carbon sequestration potential two subsystems,and evaluating the site quality of Tianmu conifer.(2)SCDS_HHI and SCPI are regarded as the evaluation index of stand carbon sequestration potential level,which are related to production levels stand,stand size structure is closely related to stand productivity,better lighting and stand size structure showed good stand productivity and carbon sequestration.(3)Stand density affection can not be considered when evaluate the site quality which make use of site index tree height curve;Aspect has a great influence on the stand tree height growth,the western slope has a high stand productivity and good stand quality.
