Application of Ecological Network in Conversion Orchard to Forest Ecological Restoration——A Case Study of Meishan Qingling in Sanya City
Considering the aspects of planning,stability,and systematization of ecological restoration,the eco-logical network of Meishan Qingling area was constructed by using the cumulative cost distance model.We ana-lyzed the regional selection,key content,construction standards,and forms of ecological restoration,and pro-posed the spatial structure scheme of ecological restoration of conversion orchard to forest.We draw the follow-ing conclusion:(1)The ecological network of Meishan Qingling area is composed of 5 ecological sources,7 ecological corridors,and 4 ecological nodes.(2)There are 3 ecological sources within Meishan Qingling area,with a total area of 525.83 hectares.The surrounding area of Maopeng Reservoir is the focus of ecological resto-ration.(3)The total length of the ecological corridor is 4.41 kilometers,which is divided into 4 confluence ecological corridors and 3 land ecological corridors.(4)The construction measures of ecological nodes can be divided into afforestation and ecological culvert construction.(5)The spatial distribution trend of ecological re-sistance is higher in central and western,central and eastern parts of Meishan Qingling,and lower in the north and south.Ecological restoration areas with low ecological resistance should be given priority,and the scale of ecological restoration map spots in areas with high ecological resistance should be expanded.
