Study On The Landscape Sensitivity In Lingshi Mountain National Forest Park Based On GIS

In this paper,the method of analysis and evaluation of landscape sensitivity was researched. According to the current situation of Lingshi mountain national forest park,the corresponding impact factors were selected and evaluation of visual sensitivity and ecological sensitivity were carried out,finally,proposals of visual protection and ecological conservation planning were raise. The aim was to protecting the highly sensitive area and developing the low-sensitive areas reasonably in order to providing a scientific basis for landscape protection,rational development of resources and optimal use of land. The main conclusions were as follows:(1)Based on GIS spatial analysis,it is studied the visual sensitivity analysis which from the four factors of relative slope of landscape,relative distance of landscape,the visual probability of landscape and the visual degree of landscape eye-catching in Lingshi mountain national forest park,the classification maps of visual sensitivity of the impact factors were obtain,and the according to the results of comprehensive analysis and evaluation. the visual sensitivity of study area was classified as fist sensitivity grades,second sensitivity grades,third sensitivity grades and fourth sensitivity grades,the area of them was respectively 148.26 hm~2,385.67 hm~2,388.52 hm~2 and 576.19 hm~2.(2)Based on GIS spatial analysis,selected elevation,slope,aspect,vegetation and hydrology factors on the ecological sensitivity analysis and evaluation,the classification maps of ecological sensitivity of the impact factor were obtain. Through the expert evaluation by AHP to determine the weight of each factor were 0.1667,0.2867,0.0733,0.3496,0.1237, and then analysis the comprehensive sensitivity through the overlay technique,at last the forest park was divided into highly sensitive area,sensitive area and low-sensitive area, the area of them was respectively 568.96hm~2,672.47 hm~2 and 257.21hm~2.(3)According to the results of the visual sensitivity analysis,Lingshi mountain national forest park was divided into four levels of visual protection zone,while based on the results of the ecological sensitivity analysis,it was divided into three levels of ecological protection zone. And then according to the actual situation of the study area presented different protective measures in different protected zone.(4)Through comprehensive analysis and evaluation of landscape sensitivity,Lingshi mountain national forest park was divided into conservation area,natural landscape protection areas,historical sites protected areas,landscape restoration areas,scenic spots and the development control area.
