By counting and analyzing the number of mountains protection, the factors to protect various kinds of mountain are identified.
    1, The degree of excavation
    2, The forest ecosystems
    3, The historical culture and tourism value
    4, Landscape
    5, Green construction land
    6, Mineral resources value
    Mandatory protection:The tourist attraction with well-preserved ecological environment and high historical cultural value
    Key protection mountains:The vegetation is good and important in ecological environment value. 

  Mountains protection
    1, General vegetation and small form of mountain is located on both sides of main urban area. Its ecological environment value is general.
    2, The mountain ecosystem was wrecked by digging and quarrying. The mountain basically meets the requirement of landscape ecology through the excavation of historical context and reorganizing of historic relics.
　

  Building by using mountain forest
    Firstly, because the quarry was dug, most of the mountains were destroyed. This plan is a detailed picture of the situation.
    Secondly, because of the urban road construction, it is necessary to excavate the mountain.
These kinds of mountains are mainly concentrated in the south of city, which belong to the mountains with good vegetation, and it is beneficial to the mountain which embodies the characteristics of the landscape. We should actively introduce the tree species adapted to the mountain cultivation, strengthen the vegetation cover, and create a good mountain style.
