一、前言植物生态型是一个种以不同的遗传性和对环境条件的适应及反应为基础的地方种群。表现为生态型变异的种的特征可以是形态的、生理的或行为性质的。一个种群的生态型分化格式一般是在不同生境或种的地理范围内的不同部分之间沿着环境变化等级的一种连续性(生态差型)变异。近年来,国外广大学者进行了大量关于森林中种群、地理、海拔和生态等倾群变异的数学分析与研究。这些数学分析都是根据森林群体的若干数量性状进行的。如叶片的长度、宽度、苗木的子叶数目、子叶平
I. INTRODUCTION The plant ecology is a species of local population based on different hereditary and adaptations and reactions to environmental conditions. The characteristics of species that exhibit ecotype variation can be morphological, physiological, or behavioral. The ecotype differentiation pattern of a population is generally a continuum (ecotype) variation along different levels of environmental change between different parts of the geographical range of different habitats or species. In recent years, a large number of foreign scholars carried out a large number of mathematical analysis and research on herd variation in forest such as population, geography, elevation and ecology. These mathematical analyzes are based on a number of quantitative traits of forest groups. Such as the length of the leaves, width, the number of cotyledons cotyledons
