摘要
本文应用Richards方程建立了慈利县杜仲人工林平均树高和平均胸径生长模型，并对有关参数和生长规律进行了全面的分析，为慈利县杜仲入工林的科学经营提供了理论依据。
The growth models of mean height and mean diameter inbreast high were estab-lished for Eucommia ulmoides plantations,using Richards Equation. Analysis of the parametersand growth regularities followed. The study can provide a theoretical framework for scientificmanagement of eucommia trees inCili County of Hunan Province.
