在诸多的森林生长模型中,单株林木的高生长率乃是一个关键性的要素。在一个已知的林分内,甚至在同龄林分内,其生长率可能极为不同。常受到象竞争、林木生活力、大、小生境的不同、遗传性变异和气候变异等因素的影响。在应用高生长率方程中,往往忽视气候和自然遗传变异。因为,数据收集和建立方程时很难把这些变量综合进去。 In many forest growth models, the high growth rate of individual trees is a key element. Within a known stand, growth rates can be very different even within the same stand. Often affected by factors such as competition, forest vitality, big and small habitat differences, genetic variation and climate variability. In applying the high growth rate equation, climate and natural genetic variation are often overlooked. Because it’s hard to integrate these variables into data collection and equation building.
