Study on the Spatial Characteristics of Landscape Services in Nature Reserve Based on Participatory Geographic Information SystemmmmA Case Study of Jiuzhaigou Nature Reserve

Abstract

This paper comprehensively adopted the Geographic Information System (GIS) and Participatory Geographical Information System (PGIS) technologies to construct the Jiuzhaigou Nature Reserve's landscape services index system and analyzed the landscape services spatial characteristics. The results show that the perception of landscape services of the Jiuzhaigou Nature Reserve varies greatly among the respondents. The number of landscape services points for rare animals habitat, forest recreation, and returning farmland exceed half of the total number, accounting for 53.78%. At the same time, the spatial distribution of landscape services points has a strong agglomeration, with the most concentrated distribution around residential areas. It can be seen that residents' perception of landscape services mainly comes from the vicinity of residential areas. With the increase in distance from residential areas, the density of landscape services points gradually decreases. The areas with the greatest intensity of landscape services are concentrated around Zharugou, Shuzhenggou and Nuorilang Tourist Service Center. The landscape services categories are unevenly distributed in different regions, and the landscape services in Shuzhenggou and Zharugou are most densely distributed.
