Research On Landscape Ecological Assessment Of Forest Park Based On GIS

Forest park is the main carrier of forest ecological tourism activities.Good forest ecological environment and good forest landscape are the main tourism resources of forest park.However,with the over-exploitation of forest tourism,the problem of forest ecological environment becomes more and more serious,and the sustainable development of forest landscape resources is seriously threatened and challenged.It is particularly important to improve the technical means and management mechanism of forest park planning,and carry out forest park landscape ecological evaluation to realize the sustainable development of forest park.With the help of GlS technology,this paper constructs a forest park landscape ecological evaluation system,which provides theoretical basis for forest park landscape ecological planning.The main conclusions of the study are as follows:(1)for evaluation of forest park,landscape,landscape ecological evaluation system,GIS technology applied in the landscape evaluation comb summary,current research situation about forest park and the landscape ecological evaluation research work in need of improvement.The ecological evaluation model of forest park landscape is constructed by taking landscape primordial degree,sensitivity degree,suitability degree and health degree as evaluation indexes.(2)combined with GIS technology,through the relative slope,relative distance,landscape visual chances and marked degree of four aspects of the concept of zhao Gao forest park landscape visual sensitivity analysis,the influence of draw various aspects of landscape visual sensitivity classification map of landscape visual sensitivity integrated hierarchical distribution,the results of the analysis concluded that primary sensitive area of 234.67 hm2,secondary sensitive area of 2305.2 hm2,level 3 sensitive area of 1347.78 hm2,level 4 sensitive area of 798.85 hm2.(3)combined with GIS technology,based on the elevation,gradient,slope direction,the types of land use,hydrology and other factors to the forest park landscape suitability is analyzed,the influence of various factors on the classification of landscape visual sensitivity distribution and comprehensive classification landscape visual sensitivity distribution,the results of the analysis it is concluded that high suitable low 110.56 hm2,regarded as 1640.56 hm2,regarded as 2948.43 hm2(4)combined with GIS technology,from the landscape types by human disturbance situation analysis of the influence of the native forest park degrees,it is concluded that the native landscape classification map,the results of the analysis it is concluded that the native landscape 3372.72 hm2,half native landscape 1054.68 hm2,artificial landscape 272.6 hm2.(5)combined with GIS technology,the vegetation coverage,landscape diversity,landscape ecological landscape health impact elasticity and it is concluded that the landscape health hierarchical distribution,the results of the analysis concludes that Gao Jiankang area of 4039.22 hm2,health in the area of 620.61 hm2,low area of 40.17 hm2.(6)combined with GIS technology,landscape visual sensitivity,suitability,native,health degrees of forest park landscape effect,it is concluded that the landscape ecological evaluation comprehensive classification map of graded protection zoning map,and put forward corresponding protection development strategy,the results of the analysis concluded that primary area of 1685.67 hm2,secondary reserve 2142.21 hm2,level 3 protection area of 872.12 hm2.
