本文从理论上推导出生态平衡施肥模型及其特征参数模型的一般应用表达式，进而建立了区域生态平衡施肥模型和区域特征参数模型，最后介绍了区域生态平衡施肥模型和地块施肥模型参数的求解方法和预测施肥量方法。研究表明：肥料效应函数模型是生态平衡施肥模型在不考虑土壤有效养分因素情况下的特例；区域生态平衡施肥模型能够满足地块半定量施肥预测的需求。%This paper established the applying models of diagnostic parameter and ecological balanced fertilization model. And then, regional ecological balanced fertilization model and regional diagnostic parameter models were found. Finally, introduced calculation methods of diag-nostic parameter and estimated methods for fertilizer dosage of regional ecological balanced fertilization model and plot fertilization model. The results showed that fertilizer effect function method was a specific instance of ecological balanced fertilization model under the condition of unconsidering soil available nutrient. Regional ecological balanced fertilization model could be used as a semi-quantitative fertilization model for plots.
