Abstract:

In order to expound the stand’s vitality and health status of Pinus massoninana plantations at present, then, offer some elementary analysis and suggestions for the operators, and reference for the assessments of forestry, the author used the method of functional key performance indication of composite structure, to build the stand’s vitality and healthy assessment indicator system of Pinus massoninana plantations, structured by 3 criteria- population vitality of Pinus massoninana, ecological health of vegetation type, and resistance vitality of stand. The diverse phases of cultivation of Pinus massoninana plantations in Hengshan Mountain was taken as sub-compartment samples to evaluate, 15 of which, with 5 distinct growing stages, were put in stand vitality and health assessments. The total stand’s vitality and healthy conditions of masson pine plantations are in a sub-healthy state, including 15 sub-compartment samples. Moreover, it was apparent that the H-value of population vitality of 5, 10, and 15 years were much more higher than those of 2 and 25 years. Besides, principally focused on the sub-compartment samples aging 2 and 25 years were in healthy state, the ecological conditions of vegetation type were dissimilar in each sub-compartment samples. However, there was little distinction in resistance vitality conditions between sub-compartment samples, and all of them were in a sub-healthy state, consistent in the total plantation.
