+## Definition
+地理连贯性（Geographic Coherence）是指虚构世界中的地理特征（气候、地形、水文、生物群系、资源分布）符合物理规律，彼此一致，无矛盾。
+
+## Core Principles
+
+### 1. Rivers Don't Split
+- Tributaries merge into rivers（支流汇入主流）
+- Rivers don't fork into two separate rivers flowing to different oceans
+- Exception: deltas, bifurcations — but these are special cases, not the norm
+
+### 2. Climate is a System
+- Rain shadows exist（雨影效应存在）
+- Coastal currents affect temperature（海岸洋流影响温度）
+- Latitude determines seasons（纬度决定季节）
+- Don't place a tropical forest at 60°N latitude without extraordinary justification
+
+### 3. Geography is Not Decoration
+- Every mountain, river, and desert has consequences for the people who live near it
+- If you put a desert there, explain how people get water
+
+### 4. Avoid Geographic Determinism
+- Geography constrains but doesn't dictate
+- Similar environments produce different cultures
+- Acknowledge agency
+
+### 5. Scale Matters
+- A "small kingdom" and a "vast empire" have fundamentally different geographic requirements
+- Communication, supply lines, and governance scale differently
+
+### 6. Maps are Arguments
+- Every map makes choices about what to include and exclude
+- Be aware of the politics of cartography
+
+## Validation Framework
+
+### Geographic Coherence Report
+```
+Region: [Area being analyzed]
+
+Physical Geography:
+- Terrain: [Landforms and their tectonic/erosional origin]
+- Climate Zone: [Koppen classification, latitude, elevation effects]
+- Hydrology: [River systems, watersheds, water sources]
+- Biome: [Vegetation type consistent with climate and soil]
+- Natural Hazards: [Earthquakes, volcanoes, floods, droughts]
+
+Resource Distribution:
+- Agricultural potential: [Soil quality, growing season, rainfall]
+- Minerals/Metals: [Geologically plausible deposits]
+- Timber/Fuel: [Forest coverage consistent with biome]
+- Water access: [Rivers, aquifers, rainfall patterns]
+
+Human Geography:
+- Settlement logic: [Why people would live here — water, defense, trade]
+- Trade routes: [Following geographic paths of least resistance]
+- Strategic value: [Chokepoints, defensible positions, resource control]
+- Carrying capacity: [How many people this geography can support]
