In the "era of sharing economy 2.0", China's B&Bs industry enjoys rapid development as a new business format, boosting regional economy to reach a new height. This paper selects the Yangtze River Delta region, China's largest economic zone, as the research area, and takes exploratory spatial data analysis (ESDA) and GIS to study the agglomeration characteristics and evolutionary trajectories of B&Bs spatial patterns amid 2013-2017. The results indicate that: (1) B&Bs in the Yangtze River Delta region exhibit balanced development. (2) From the perspective of global spatial autocorrelation analysis, B&Bs spatial distribution features significant spatial autocorrelation, with spatial agglomeration degree on the rise. (3) From the perspective of local spatial autocorrelation analysis, it gradually shows a gradual decreasing pattern from the east to the west, forming a significant high concentration of eastern cities and a low concentration of western cities. By comparing the results of the 3 years, Huzhou and Shanghai showed a significant high concentration from 2013 to 2015, and neighboring cities such as Suzhou, Jiaxing and Hangzhou have shown a high approaching trend, indicating that in recent years, the development awareness of the industry is converging. (4) The four factors: endowment of tourism resources, transportation convenience, policy conditions and residents' living standards exert important influences on B&Bs spatial distribution.

Bing et al.: Study on the spatial relationship between landscape recreation service demand and urbanization -a case study in Shanghai -7535 -

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.
