Research On The Forest Park Planning Based On GIS Spatial Analysis

Forest Park is the main carrier of forest eco-tourism activities.Good forest ecological environment and high-quality forest landscape are the main tourism resources of Forest Park.However,with the over exploitation of forest tourism,the problem of forest ecological environment is increasingly prominent,and the sustainable development of forest landscape resources is seriously threatened and challenged.Therefore,how to scientifically plan and improve the planning mechanism of Forest Park has become an urgent problem.This paper starts with the ecological sensitivity of the land,based on the GIS spatial analysis technology,analyzes the sensitivity of the forest park land,and then carries on the ecological function division according to the sensitivity analysis results.Then,the paper plans and organizes the tour route of the forest park by means of spatial overlay and other analysis tools.At last,it makes a scientific research on the site selection of the key projects of the forest park.In the planning,a series of GIS spatial analysis technologies are used to avoid randomness and blindness,to ensure the scientificity of forest park planning,and to achieve the sustainable development of forest economy such as water and soil conservation,water conservation and other ecological functions of the park,material supply of forest products,eco-tourism,health and self-cultivation.The specific research contents are as follows:(1)Land sensitivity analysis.In this paper,based on the basic knowledge of ecology,forestry and other related theories,with the help of GIS spatial analysis technology,a relatively comprehensive evaluation index system of ecological sensitivity of forest parks is constructed.Using this set of ecological sensitivity index system,the ecological sensitivity of all parts of forest parks is analyzed in detail.It provides a scientific basis for the planning of Longshan Forest Park.(2)In the construction of ecological sensitivity evaluation index system of Forest Park,three standard level factors and nine index level factors are selected synthetically.Through expert scoring and analytic hierarchy process(AHP),the weight values of evaluation index factors are established.The results of ecological sensitivity analysis show that the area of high sensitivity is 3565.02 Hm2,accounting for 38.39%of the total area of the forest park,the area of medium sensitivity is 2442.93 Hm2,accounting for 26.31%of the total area of the forest park,and the area of low sensitivity and low sensitivity is 3278.22 hm2,accounting for 35.31%of the total area of the forest park.According to the distribution of each ecological sensitive area,the corresponding ecological function zoning of the park is carried out.(3)Following the planning principle of the best benefit,the shortest route and the most reasonable combination,the tour organization route is designed by using GIS network space analysis technology.According to the distribution of park attractions and the existing tour routes,the cost distance and cost direction are calculated by the distance analysis tool,and then the best route map of tour organization route is obtained.(4)Use GIS analysis tools to select the location of key construction projects.Based on the GIS buffer zone and overlay analysis,according to the ecological and land demand of the health care base,combined with the results of ecological sensitivity analysis,the final location result map of the forest health care base is obtained,which provides the basis for the location of the forest health care base construction of Longshan Forest Park,and provides the theoretical reference for the development and construction of other key projects in the early stage of the forest park.
