Spatial Pattern Analysis of Geohazards and Human Activities in Bailong River Basin

China is a country at serious risk from geohazards. With the development of the social economy, the effects of climate change and increment of human activity, the ecological environment has deteriorated. Due to the frequent occurrence of geohazards, not only has the safety of human lives been threatened, but regional sustainable development has also been greatly influence. This paper mainly aims at analyzing correlation and spatial pattern between human activities and geohazards in the Bailong River Basin. Results showed that the correlation coefficient between the settlements and landslide sites is 0.361; meanwhile, the correlation coefficient between settlements and debris flows reaches 0.620. Besides, the spatial distributions of the per-unit-area biocapacity and geohazard sites (landslides and debris flows) are very similar, and the correlation coefficient between total biocapacity and two types of geohazard is respectively 0.217 and 0.562. All results above showed that the greater the density of human activities in this region, the more disasters occurred. The studies indicated a significant correlation, and showed that human activity is the most important influential factor inducing geohazards. We explore the mechanism factors of natural disaster, which have a great significance for disaster management and sustainable socio-economic development.
