| 摘 要： | 为了提高面向林业主题知识系统的知识数量与质量, 在研究知识模型现状的基础上, 结合林木的生育特点, 提出了林木知识模型建立的基本依据是林木生育时间和造林技术措施, 并依此建立由浅知识模型和深知识模型所组成的林木三维知识模型(以杨树为例)。并对该知识模型的知识表示和模糊推理进行了描述, 该知识模型具有一定的通用性。

| Abstract: | In order to improve the quality and increase the quantity of the knowledge on the knowledge system of forest-oriented subject, this paper pointed out that the foundations of building the knowledge model(KM) for the forest-oriented subject are the growth-development time and the afforestation techniques on the basis of the study of the present situation of knowledge model and by combing the properties of forest growth and development. The three-dimensional knowledge model for poplar constituted of superficial KM and deep KM is built according to the above view. The knowledge representation and the fuzzy reasoning for this model were described. The knowledge model is of versatility to a certain degree. |
