摘 要:提出林木损失额的价值计量以损毁程度系数(Kd)作为调整值,并且对树木的生理损毁、观赏损毁、生理和观赏部位同时损毁三种受损类型分别进行讨论,提出根据树木损毁程度(d)与价值损失之间的强度系数(ε)来确定损毁程度系数的方法。根据损毁程度系数计算公式Kd=dε,计算得出不同损毁程度下树木生理损毁程度系数值。其意义在于解决了由于林木损伤程度的不同,而体现出林木价值损失额的不同,从而为更加准确、合理地计量林木损失额提供了科学依据。There were three statuses of damage for different forest types: biological damage, view damage, concurrent of physiological damage and view damage. This paper discusses three types of damage, puts forward corresponded calculation method and formula, and puts forward method which be used to calculate degree coefficient of trees ac- cording to damage degree of trees (d) and loss of the value of trees intensity coefficient (e). Determinant standard of different biological damage degree of conifers and broadleaf were constituted separately according to their different biological characters. Biological damage degree coefficient of conifers and broadleaf were calculated. View damage degree coefficient of trees was calculated by using the determinant standard of biological damage degree of broadleaf for reference. The assuring method of damage coefficient putting forward provide scientific basis for accurate and reasonable estimation of the loss of forest tree.
关 键 词:生理损毁 观赏损毁 损毁程度 强度系数 损毁程度系数
