梯田为什么比直直的坡地更不容易水土流失？
Why do terraces lose less soil and water than a bare slope?
一级级田埂像台阶把坡面"打断"，减缓水流、留住泥土；水慢慢下渗而不是一路冲走表土，坡就成了能耕能保的田。
Each riser breaks the slope like stairs, slowing flow and holding soil; water seeps in instead of washing topsoil away, turning a slope into farmable, stable land.

"森林—村寨—梯田—水系"四素同构，藏着什么生态智慧？
What ecological wisdom hides in the "forest-village-terrace-water" four-element structure?
它把水源林、人居、生产田和水道按海拔排好位置，让水自动分配、养分循环、风险分散；不是征服地形，而是顺着地形设计生活。
It arranges water-source forest, homes, fields and channels by elevation so water self-distributes, nutrients cycle and risks spread—designing life with the terrain, not against it.
