    3. Cheerful lawn

    Less than 3/5 of the border around the lawn is not above the eye level of the scene barrier, called this lawn cheerful lawn.

    4. Savanna lawn

    When the lawn sparse distribution plant trees and shrubs, great spacing, when these trees covering an area (canopy density) of 20% to 30% of the total area of ​​the lawn, known as the savanna lawn. The savanna Lawn for large numbers of people recreation lawn, has a certain shade of conditions, sometimes compared with the views of the lawns.

    5. Sparse lawn

    6. Understory lawn

    In the canopy density greater than 70% of the jungle, or within the groups of trees understory, understory light transmission coefficient is small, positive Gramineae difficult to grow, can only grow some more water content of negative herb, species of woodland and groups of trees, due to the spacing of the trees is very dense, not suitable for visitors in the understory, too many visitors to enter, it will affect the growth of trees, understory negative herb high water content within the organization, stampede resistance, thus understory grass to watch and maintain soil erosion, visitors are not allowed to enter.
