4. Structural differences: "Green Mountain and Green Water" is an idiom composed of two semi-formal compound words: "Green Mountain" and "Green Water"; "Beautiful scenery" is an idiom consisting of two subject-predicate phrases: "Beautiful scenery" and "Beautiful water".

It must be described by adjectives, so it must be written as "beautiful scenery"
