分享我在 Obsidian 中实践的个人知识管理系统,包含三层架构、命名规范和链接原则The personal knowledge system I run in Obsidian: three layers, naming rules, and a bias toward links.
“你的笔记系统不是存储信息的仓库,而是思考的工具。“——这是我实践 PKM 多年来最深的体会。
在信息爆炸的时代,我们不缺信息,缺的是将信息转化为真正属于自己知识的能力。这篇文章分享我在 Obsidian 中建立的个人知识管理系统,核心方法论来自 Andy Matuschak 的常青笔记(Evergreen Notes)理念。
为什么需要系统化的知识管理
每天我们都会接触大量信息:公众号文章、播客、书籍、论文……但大多数信息读过即忘,真正能被记住并随时调用的少之又少。
传统笔记的问题在于:
- 碎片化:笔记之间孤立存在,无法形成网络
- 难以复用:记过的笔记,下次想用时找不到或看不懂
- 维护困难:笔记越来越多,但质量参差不齐
一个好的 PKM 系统应该让笔记越积越多,而不是越积越乱。
三层架构:资料 → 原子 → 索引
我的笔记系统采用三层架构,每层有明确的职责:
第一层:资料笔记(Material Notes)
这是信息的原始来源——读过的文章、书籍笔记、会议记录、灵感随想。
特点:
- 保留原始出处和上下文
- 可能比较长、比较杂
- 是原材料,不是最终产品
第二层:原子笔记(Atom Notes)
这是系统的核心。常青笔记应当是原子化的——每个笔记只表达一个核心想法,便于独立使用和组合。
特点:
- 一个笔记,一个想法
- 用自己的话重写,不是简单摘录
- 可以被其他笔记引用和链接
第三层:索引笔记(Index Notes)
相当于笔记的「目录」和「地图」,将相关原子笔记组织起来。
常见形式:
- 主题索引:汇总某个主题下的所有笔记
- 概念索引:解释一个复杂概念及其关联
- 项目索引:特定项目相关的笔记集合

└────────── 双向链接 ←─────────┘命名方法论:陈述句标题
命名是我笔记系统中非常重要的一环。一个好的标题应该:
用陈述句,而不是短语
| ❌ 避免 | ✅ 推荐 |
|---|---|
| 写作技巧 | 写作时先完成再完善 |
| 复利效应 | 复利效应让小的优势不断累积 |
| 深度工作 | 深度工作需要刻意练习 |
以概念为导向
标题应该指向一个概念或观点,而不是一个任务或项目。
便于未来检索
当你三个月后搜索时,输入什么能最快找到这篇笔记?标题应该能回答这个问题。
链接的艺术:密集链接原则
“笔记之间的链接比笔记本身更重要。”
这是我最常跟别人分享的一句话。单个笔记的价值有限,但当笔记形成网络,就会产生 1+1>2 的效果。
为什么要密集链接
- 触发联想:看到一篇笔记,能想到相关的其他笔记
- 发现洞见:通过链接发现意想不到的连接
- 构建视角:不同的索引方式呈现不同的知识结构
链接的实践技巧
- 看到任何相关就链接:不要等”完美”时机,现在就链接
- 双向思考:链接到 A 时,想一想 A 会链接到什么
- 用链接代替分类:与其把笔记放在某个文件夹,不如用链接连接它
笔记的生命周期:种子 → 萌芽 → 常青
不是所有笔记生来平等。我的笔记有三种状态:
🌱 种子笔记(Seed Notes)
初级的、想法萌芽状态的笔记。
- 零碎的想法、待验证的信息
- 需要进一步加工
- 可能是资料笔记的摘录
🌿 萌芽笔记(Sprout Notes)
已经整理过但还不够成熟的笔记。
- 用自己的话写过
- 有基本的结构
- 但还需要更多链接和补充
🌲 常青笔记(Evergreen Notes)
成熟的、可以独立存在的笔记。
- 原子化的:一个笔记,一个核心想法
- 可复用的:可以被多个上下文引用
- 链接充分的:与相关笔记形成网络
🌱 种子 → 🌿 萌芽 → 🌲 常青
↓ ↓ ↓
需加工 整理中 可复用笔记应该在这个生命周期中流动,而不是静止在某个状态。
实践工作流:从阅读到输出
最后分享我的完整工作流:
1. 收集阶段
遇到有价值的内容,先快速保存。可以使用:
- 稍后读工具(Pocket、Instapaper)
- 微信/Flomo 快捷输入
- 直接保存到笔记库的收件箱
2. 处理阶段
定期(建议每天或每周)处理收集的内容:
- 提取核心想法
- 用自己的话重写
- 归类到相关主题
3. 链接阶段
这是最容易被忽视但最重要的步骤:
- 思考这篇笔记与哪些已有笔记相关
- 主动建立双向链接
- 更新相关索引笔记
4. 输出阶段
当你积累到一定程度,写作就变得自然:
- 笔记网络本身就是写作素材
- 索引笔记就是文章大纲
- 常青笔记就是文章段落
总结
我的 PKM 核心原则:
- 原子化:一个笔记,一个想法
- 链接优先:笔记之间的连接比笔记本身重要
- 持续演进:笔记有生命周期,要不断迭代
- 命名即思考:好的标题是思考的开始
工具永远不是重点,重点是建立思考的习惯。当你开始认真对待每一篇笔记,你会发现知识真的会「生长」。
“Your notes are not a warehouse for information. They are a tool for thinking.” — that is the deepest lesson of years of PKM.
We do not lack information. We lack the ability to turn it into knowledge that is actually ours. This is the system I run in Obsidian. The core method comes from Andy Matuschak’s Evergreen Notes.
Why a system at all
Every day we take in a lot: articles, podcasts, books, papers. Most of it is gone by the next day. Very little can be recalled on demand.
The usual problems with notes:
- Fragments: notes sit alone, never a network
- Hard to reuse: you wrote it, then you cannot find it, or cannot read it
- Hard to maintain: more notes, uneven quality
A good PKM system should mean more notes without more mess.
Three layers: material → atom → index
Each layer has a job:
Layer 1: Material notes
The raw intake — articles, book notes, meeting notes, stray thoughts.
- Keep the source and the context
- They can be long and mixed
- Raw material, not the finished thing
Layer 2: Atom notes
The core. Evergreen notes should be atomic — one idea each, so they can be used and combined on their own.
- One note, one idea
- Rewritten in your own words, not a paste
- Other notes can cite and link them
Layer 3: Index notes
A table of contents and a map: they gather related atoms.
Common shapes:
- Topic index: every note under a subject
- Concept index: a hard idea and its neighbors
- Project index: notes for one project
material ──extract──> atom ──organize──> index

└────────── bidirectional links ←─────────┘Naming: titles as sentences
Naming is a load-bearing part of the system. A good title should:
Prefer a sentence over a phrase
| ❌ Avoid | ✅ Prefer |
|---|---|
| Writing tips | Finish first, then polish |
| Compound interest | Compound interest lets a small edge accumulate |
| Deep work | Deep work has to be practiced on purpose |
Point at a concept
The title should name a concept or a claim, not a task or a project.
Be findable later
Three months from now, what would you type to find this note? The title should answer that.
The art of linking: density over folders
“The links between notes matter more than the notes.”
That is the line I repeat most. One note is limited; a network of notes is 1+1>2.
Why dense links
- Trigger association: one note reminds you of others
- Surprise insight: links you did not plan
- Build a viewpoint: different indexes, different structures
Practice
- Link when you see a relation — do not wait for the perfect moment
- Think both ways — if you link to A, what does A link to?
- Prefer links over folders — connect it instead of filing it
Lifecycle: seed → sprout → evergreen
Notes are not born equal. Mine have three states:
🌱 Seed notes
Early, half-formed.
- Fragments, claims not yet tested
- Need more work
- Often excerpts from material notes
🌿 Sprout notes
Rewritten, not yet mature.
- In your own words
- A basic shape
- Still need more links and filling-in
🌲 Evergreen notes
Mature enough to stand alone.
- Atomic: one note, one core idea
- Reusable across contexts
- Well linked
🌱 seed → 🌿 sprout → 🌲 evergreen

needs work in progress reusableNotes should move through this life, not freeze in one state.
Workflow: from reading to writing
1. Capture
Save what is worth it, fast:
- Read-later tools (Pocket, Instapaper)
- WeChat / Flomo quick capture
- Straight into the inbox of the vault
2. Process
On a cadence (daily or weekly):
- Pull the core idea
- Rewrite it
- Place it near a related theme
3. Link
The step people skip, and the one that matters:
- Which existing notes does this touch?
- Make the bidirectional links
- Update the relevant indexes
4. Output
After enough accumulation, writing gets easier:
- The network is the source material
- Index notes are outlines
- Evergreen notes are paragraphs
In short
- Atomic: one note, one idea
- Links first: the connections matter more than the note
- Keep moving: notes have a life; they should iterate
- Naming is thinking: a good title is the start of a thought
Tools are never the point. The habit of thinking is. Treat each note seriously, and knowledge really does grow.
