Land Suitability Evaluation Of Maofeng Mountain Forest Park In Guangdong Province Based On GIS

Forest park is the one built by a large area of natural forest or artificial forest as the main part.In the planning process of forest park,the unsystematic planning method leads to blind development and utilization,which has a huge negative impact on the ecological environment and is not conducive to the subsequent development.Scientific and reasonable planning of the functional zoning and tour route of forest park is the key to ensure the sustainable and healthy development of it.We selected Maofeng Mountain Forest Park in Guangdong Province as the research object,based on the spatial analysis function by software of Geographic Information System(GIS),combined with Analytic Hierarchy Process(AHP)to evaluate the forest park of land suitability.According to the results of suitability,we put forward the optimization suggestions of functional zoning and tour route to avoid subjectivity and blindness in planning.The main findings of the study are:(1)Combined with the related theoretical knowledge of forestry and ecology,the land suitability evaluation index system of Maofeng Mountain Forest Park in Guangdong was constructed.Nine factors were determined as evaluation factors,including elevation,slope,aspect,water area,vegetation type,vegetation coverage,natural landscape source,human culture landscape source and road traffic.We found that the suitability of water area,natural landscape source,vegetation type and human culture landscape source is good,but the suitability of elevation and aspect is poor.(2)Using the expert scoring method and AHP,the weights of each factor were calculated as follows:The elevation weight is 0.0270,the slope is 0.0680,the slope aspect is 0.0429,the water area is 0.2401,the vegetation type is 0.1213,the vegetation coverage is 0.0607,the natural landscape source is 0.2291,the human culture landscape source is 0.1145,and the road traffic is 0.0964.(3)By superimposing the weight results,it can be concluded that most of the land in the park is suitable for development and construction,among which:The area of forest park is 6971.90 hm2,of which the suitable area is 2575.82 hm2,accounting for 36.95%of the total area,the suitable area is 1243.93 hm2,accounting for 17.84%of the total area,and the most suitable area is 661.51 hm2,accounting for 9.49%of the total area.In the forest park,the unsuitable and less suitable areas were distributed from the west to the east,with an area of 658.21 hm2 for the unsuitable area and 1832.43 hm2 for the less suitable area.(4)Based on the results of suitability evaluation,optimization suggestions were put forward for functional zoning and tour route organization of Maofeng Mountain Forest Park in Guangdong.The future planning should adjust the area of the general recreational and ecological conservation partition,increase the area of inward and outward tourist service partition,ensure the planning region partition is suitable for basic construction,and organize the best tour route which pass the park partition and core scenic spot with the lowest cost.The conclusions provide reference basis for the subsequent effective development and utilization of forest park.
