分形理论是当今世界上非常流行和活跃的一门新兴理论和学科。分形理论不仅具有自然界中的美学韵味，而且又可以通过数学公式和计算机技术产生了许多新的美感。本文介绍了分形理论的概念、特点和美学意蕴，并以山川地貌为灵感，运用分形理论设计了一款组合花架。文章首先简要介绍了分形理论的由来、发展和应用领域，然后分析了分形理论的自然特点和几何特征，以及分形理论所蕴含的美学规律和价值。接着，文章通过案例学习，展示了分形理论在多功能家具设计中的运用，说明了如何利用分形曲线生成元进行迭代变换，创造出新颖的造型语言。最后，文章详细描述了作者基于分形理论的组合花架外形设计过程，包括工程制图、建模过程和渲染效果，并总结了分形理论在设计实践中的意义和难点，以及作者的个人感悟。

Fractal theory is an emerging theory and discipline that is very popular and active in the world today. Fractal theory not only has the aesthetic flavour in nature, but also can produce many new aesthetics through mathematical formulas and computer technology. This article introduces the concepts, characteristics and aesthetic implications of fractal theory, and designs a combined planter using fractal theory inspired by mountain and river landscapes. The article firstly briefly introduces the origin, development and application fields of fractal theory, and then analyses the natural features and geometric characteristics of fractal theory, as well as the aesthetic laws and values embedded in fractal theory. Next, the article demonstrates the use of fractal theory in multifunctional furniture design through case studies, illustrating how iterative transformations can be performed using fractal curve generating elements to create a novel modelling language. Finally, the article describes in detail the author's design process of the shape of the combined planter based on fractal theory, including engineering drawings, modelling process and rendering effect, and summarises the significance and difficulties of fractal theory in design practice, as well as the author's personal insights.
