乡村设计学作为一门新兴的交叉学科,是构建中国自主设计学知识体系的重要组成部分。笔者20余年来（2004—2026年）持续探索的中国当代设计学理论体系建构为学术背景,以“设计世界”为逻辑基点,系统阐述乡村设计学的核心理论问题。文章深入考察乡村设计学的研究对象——全生命体设计,阐明其核心原则“本天利人”、世界观与方法论“体系思维”、认识论“打开理论”以及成果论“知行能成理论”。在此基础上,文章构建了乡村设计学的六大核心结构体系——生产设计学、生活设计学、生态设计学、文化设计学、社会设计学与教育设计学,并探讨其未来发展路径。研究认为,乡村设计学体系是一种基于全生命体设计理念、以“本天利人”为根本原则的综合性设计理论架构。该体系以农业设计为根本,以工业设计、数智设计、服务设计为工具,融合乡村生产、生活、生态三大设计学子系统（即“三生融合”）,并呈现出全息性的结构特征,其本质是一种面向未来的设计学体系,对推动乡村全面振兴、实现城乡融合发展具有重大理论价值和现实意义。

As an emerging interdisciplinary field, rural designology is an important part of building the knowledge system of independent design in China. This article takes the construction of the theoretical system of contemporary Chinese designology that the author has continuously explored over more than twenty years (2004-2026) as its academic background, and uses the "Design-world" as its logical basis to systematically elaborate on the core theoretical issues of rural designology. The article delves into the research object of rural designology—whole-life design, and clarifies its core principles of "benefiting people from nature", worldview and methodology "systems thinking", epistemology "opening theory", and outcomes theory "theory of knowledge and action to achieve success". On this basis, the article constructs six core structural systems for rural designology—Production Designology, Life Designology, Ecological Designology, Cultural Designology, Social Designology, and Educational Designology—and explores their future development paths. The study believes that the rural designology system is a comprehensive design theoretical framework based on the concept of whole-life design and fundamentally based on the principle of "benefiting people from nature". This system is fundamentally based on agricultural design, with industrial design, digital intelligent design, and service design as tools, integrating the three major designology subsystems of rural production, living, and ecology (i.e., the "integration of three rural aspects"), and exhibits a holographic structural feature. Its essence is a future-oriented designology system, which holds significant theoretical value and practical significance for promoting comprehensive rural revitalization and achieving urban-rural integrated development.
