限制因子原理在植物生产量预测中的应用

Application of the Principles of Limiting Factors to Prediction of Plant Production

一、限制因子原理概述一种生物体要在某个环境中生存和繁荣,必须得到所需要的基本物质,而这些因素的各种数量和质量及其相互作用会对生物产生不同的影响。研究各种因素对植物生长影响的先驱者Liobig提出了“

The principles of limiting factors are analysed and reviewed, and on this basis, the dynamic model of plant production is designed and simulated which can better reflect the effects of climate(temperature, water, light etc.), basic ground(physical geography, soil), investment and their interactions on plant production. The model has been applied to the prediction of wheat yields in the west district of the Yellow River in Gansu province and satisfactory results are obtained.
