| With the rapid development of computer technology and gradual mature of GIS application, GIS had powerful spatial analysis and date management capabilities, and provided the theoretical reference for organizing and analysis the tour line in forest park. This paper attempts to use GIS technology with space analysis capabilities, and tour road selecting to Ling-shi Mountain National Forest Park was researched , then the factors which affect tour road selecting of forest park were analyzed, four important quantitative factors were selected. There, it used analysis hiberarchy process and ranking evaluation, then the tour road selecting way of Ling-shi Mountain National Forest Park was established based on GIS technology. Accordingly, quantitative study was carried out to tour road selecting of forest park. The network analysis function was applied, according to the result of questionnaire investigation to visitors, and integrated the characteristic of sight sources in Ling-shi Mountain National Forest Park, qualitatively and quantitatively combination tour lines with different topics were got. Finally the 3D visualization of tour line in Ling-shi Mountain National Forest Park based on GIS technology was took, and the methods of combination to tour line for forest park were discussed. The conclusions were that:(1) The tourists'questionnaire investigation showed that 60% of the tourists'age, of whom visiting Ling-shi Mountain National Forest Park, were ranging from 21 to 40. The main visiting mode was friends and relatives, and 57.5% out of the tourists selected the one-day tour. The most popular campaign were mountain climbing and view enjoyment, which had a proportion of 83.9% and 76.5% respectively. The proportion of the tourist satisfied and unsatisfied out of the total number were 58.3% and 19.4%. The questionnaire analysis would supply a good basis for defining the tour line subject of Ling-shi Mountain National Forest Park.(2) The important factors which affect tour road selecting were analyzed, and elevation, gradient, land category and sensitive vision as the basic grid layer were chose, then the weight and score of the factors in tour road selecting way by analysis hiberarchy process and ranking evaluation were ascertained, the score range was 0 to 100, and the weight were 0.28, 0.17, 0.06 and 0.49 respectively. The cumulative score of tour road selecting to Ling-shi Mountain National Forest Park was got by layer superposition, and cumulative score formula was: R = 0.28×El +0.17×Sl+0.06×Ge+0.49×La. Then, drawing on the technology of minimal distance analysis, the best tour line which used shortest path analysis to grid date based on GIS and sight spot date collected by GPS was chose.(3) The tour road selecting way was applied to get the tour line of Ling-shi Mountain National Forest Park, and compared with the road track, it showed that the coincidence degree was 80 %. According to the questionnaire investigation, analyzing the tourists'satisfaction degree to the tour line and its reasons, were added three lines:①Jiudie peak forest landscape zone to Dingdang waterfall;②Woxian stone to Liuxue peak;③Bluff ancientry to Dingdang waterfall. The three roads were all feasible after field surveying.(4) Applied the network analysis of GIS technology and combined with the result of questionnaire investigation for Ling-shi Mountain National Forest Park, then, the residence time was statistical and estimated, considering the characteristic of landscape zone and two traffic ways walking and driving, we got four one-day tour line with different topics:①The tour line which take the sight-see and pilgrimage human landscape as topic and view the nature landscape as assistant;②The tour line which mix nature landscape with human landscape;③The tour line which suit for the man dare to venture and enjoy experience of outside;④The tour line which include leisure, recreation and healthcare. |
