Study On Plant Landscape Restoration In Damaged Area Of Shidonggou Forest Park In Liaoyang

For the forest park,plants are the most significant landscape resources,it is extremely important to create the good plant landscape for improving the park’s quality of the landscape,elevating the influence of the park,and increasing the income.In 2015,Liao Yang SDG forest park happened a serious forest fires that made the serious damage to the plants,it caused lots of vegetation areas incompleted,reducing the beauty of the park,affecting the forest recreation activities,In this article,from the analysis and evaluation of the damaging areas and plants,we can make some plant landscape restoration strategy for the park from the angle of the landscape.(1)In the first place,this article make an analysis to the damaged area and landscape visual sensitivity,then find out that canopy fire area is distributed in landscape visual secondary sensitive area in the west of forest park;surface fire is distributed in landscape visual secondary sensitive area in the west of forest park;The southeast area of the forest park is well preserved.(2)Furthermore,the article make a statistics on the same area with SDG forest park of the department of forest vegetation in the province and to ensure important local application of tree species(L.olgensis、Picea asperata、P.tabulaeforymis、Jugians mandshurica、Alnus japonica Sieb、Populus Canadensis、Acer pseudo-sieboldianum、Acer mono Maxi.、Quercus wutaishansea.etc.).(3)By Analytic Hierarchy Process,establishing the selecting repaired tree species suitability evaluation system,evaluate the damage areas needed repair and make sure the suitable repair added tree vegetation Restoration suitability evaluation includes the following species:ornamental value(including the ornamental value of the flower,leaves and fruits);growth characteristics(resistance to the potential,the growing,requirements);the economic value(the seedling price,the application way);the ecological value(fire retardant function,soil and water conservation function,conditions for the wildlife activity function,ecosystem carbon sequestration function);additional function(cultural imagery function,the popularity of the culture function,the secretion of antiseptic material function,secretion of aromatic substances function).(4)Through the evaluation and analysis,the repairtion in the primary landscape visual sensitivity area choose Pinus tabuliformis、Pinus sylvestris var.mongolica、Larix olgensis that used to be dominant tree species in main.Supplementary tree species can use:Koelreuteria paniculata、P.sibirica、Syringa amurensis.、L.olgensis、Pyrus ussuriensis、P.koraiensis、Amygdalus davidiana,Acer pseudosieboldianum,Acer pictum subsp、Koelreuteria paniculata.In the base of restoring original vegetation,the repairation in the secondary landscape visual sensitivity area could choose the following species:Koelreuteria paniculata、Lespedeza bicolor、P.X Canadensis、Syringa amurensis、Koelreuteria paniculata、Amorpha fruticosa、Q.liaotungensis.、Robinia pseudoacacia、jugians mandshurica、P.tabulaeformis.In the three-level landscape visual sensitive areas,the repairation in the base of adding dominant spieces like Pinus tabuliformis,Juglans mandshurica,Xylosma racemosum etc,also need to add species like:Lespedeza bicolor.、Koelreuteria paniculata、Salix babylonica、Morus alba、Robinia pseudoacacia、Pterocarya steopcera、Amorpha fruticosa、Ulmus propinqua、B.Platyphylla.In the view of landscape and forest tourist,the article make some plant landscape repaired strategies to the damaged area in ShiDongGou Forest Park,Liaoyang,in order to giving some advice to afforestation design,regaining and improving the quality of plant landscape in the forest park.
