    Settlement typeIdentification standardSourcesInterpretation reference
    DeclineSigns of cultivation near settlements are disappearing and abandoned land trends are clear; the landscape tends to be monotonous; the colors of residential locations are dim; and surrounding roads are gradually replaced by “forest-shrub-grass”.CNES AstriumQuick Bird(0.51 m)
    StagnationThe distribution of the surrounding farmland is scattered and there are no signs of consolidation; the overall landscape pattern is balanced; the colors of residential locations are generally dark; and infrastructure construction is declining.
    DevelopmentThe surrounding farmland shows order and there are signs of consolidation; a weak fruit forest planting trend appears; the ecological landscape tends to be diverse; the colors of the residential locations are white; and individual homes are clear.
    VigorClearly fruit forest planting trend near the settlements; the surrounding infrastructure is complete; the landscape is diverse; the colors of residential locations are bright; and the stereo perception of the settlements is strong.
