摘要
用数理统计的方法，对不同立地条件、不同树龄及不同类型栗树的叶片面积与其叶片长度、宽度和长×宽分别进行线性回归分析，得出各自的高度相关的回归方程，为板栗叶面积的测定，提供一个简单实用、可靠性较高的方法。
This paper deals with linear regression analysis respectively on the leaf area,the length,the width of leaf or their product in different plai1ting conditions,tree ages and types of Chi-nese chestnut trees with the method of mathemiaticat statistics。It obtains respective linear re-gression equation of high correlation,thus providing a simple and practical method of highreliability for the determination of leaf area of Chinese chestnut tree。
