Question

I make a Scrollview.When i scroll the view, the scene below also respond.

How to make it only respond GUI event when touch the region of GUI component

Answer 1

private float scroll_value;
private Rect vscroll_rect = new Rect(0,0,100,100);
void OnGUI () {
    scroll_value = GUI.VerticalScrollbar (vscroll_rect , scroll_value, 1.0f, 0.0f, 10.0f);
}
void Update() {
    // Cursor is inside verticalscroll rect, ignore it
    if (vscroll_rect.Contains(Input.mousePosition))return;
}

The only problem is that if you have several GUI elements in many different scripts they each need to test if Input.mouseCursor is inside a GUI element. One easy way around that is to create a single script that manages GUI rects which you can call from any other script to check.
