[Responses of radial growth of to climate change at the northern slopes of Qinling Mountains, China].

A standard chronology (STD) was established with samples collected from Nanwutai at the northern slopes of the Qinling Mountains. The correlations between radial growth of and climatic factors were explored. The results showed that radial growth was positively correlated with moisture factors in previous September and current May.

Landscape pattern change and its response to anthropogenic disturbance in the Qinling Mountains during 1980 to 2015.

Understanding landscape pattern change and its response to anthropogenic disturbance is of great significance for ecosystem conservation and management. Based on high-precision land use data from 1980 to 2015, we studied the spatial and temporal changes of landscape patterns in the Qinling Mountains and its response to anthropogenic disturbance by using the landscape pattern vulnerability index and human disturbance degree constructed by the landscape pattern index and the surface coverage classification system. The results showed that the degree of landscape fragmentation gradually increased in the Qinling Mountains.
