反映植物性状特征的W-T模式

A W-T MODEL ON PLANT CHARACTERISTICS

本文依据任何一个环境因子对植物生长发育与产量影响都存在3个基点,通过必要的简化假设,推导出一个简单适用能反映各种植物性状特征(如单产、材积量、平均胸径等)与水热因子关系的W—T模式,经检验拟合效果好,并可进一步用于植物分布、配置、产量分析以及气候变化对农林影响研究等方面。

The effects of environmetnal factors on plant growth and production have three basic points, maximum, optimum and minimum. Based on necessary hypotheses, a simple W-T model, which describes the relationship between biological characte-ristics (e. g. per unit area yield, volume of timber, average chest diametre, etc.) and water-thermal factors, is presented. This model coorsponds with the observa-tion data, and can be applied to the analysis of distribution, and yield of plant, and, the effect of climatic chang on agroforestry.
