Spatial-temporal shifts of ecological vulnerability of Karst Mountain ecosystem-impacts of global change and anthropogenic interference

Spatiotemporal Distribution and Influencing Factors of Ecosystem Vulnerability on Qinghai-Tibet Plateau

“…Standardization is generally carried out to solve the issue of inconsistent original data units [ 53 ]. There are two relationships between ecosystem vulnerability and evaluation factors [ 65 ].…”

“…In this study, the Sensitivity-Resilience-Pressure (SRP) model was used to construct the index system. This model is constructed based on the connotation of ecosystem stability and has been widely used in the Karst Mountains [53], the Yimeng Mountain area [45] and the Shiyang River region [54], among others. Here, sensitivity reveals the resistance of the ecosystem to various disturbances and is usually expressed by topographical and meteorological factors.…”

“…The selected 12 indicators were divided into three categories, namely sensitivity, resilience and pressure (Table 4). In previous studies of ecosystem vulnerability in Shiyang River Basin [54], Karst [53] and Yimeng [45] mountainous areas using SRP model, sensitivity is considered to be the product of the interaction between the topographic factors and the distribution of meteorological factors. In this study, annual average temperature, annual precipitation and ET were just selected to reflect the hydrothermal conditions of the ecosystem [10,28].…”

Effects of rhizosphere fungi on the chemical composition of fruits of the medicinal plant Cinnamomum migao endemic to southwestern China

“…Researchers have suggested that the chemical components of C. migao fruit may be closely related to the climate of the small watershed in the plant’s distribution region [ 9 , 79 ]. Karst landforms characterize the geography of southwest China; this special geomorphic discontinuity has formed many small watersheds with different climates [ 19 ]. The climate differences formed by this special geographic area also promoted species differentiation and rich species diversity, including the ecological differentiation of fungal populations to form special ecologically functional populations [ 42 , 62 ].…”

Spatial–temporal change patterns of vegetation coverage in China and its driving mechanisms over the past 20 years based on the concept of geographic division

“…As the main body of terrestrial ecosystems, vegetation is exceedingly sensitive to the changes of various factors due to the influence of climate, geomorphology, soil and other natural and man-made factors. Therefore, the study of vegetation dynamics (especially large-scale and long-term vegetation coverage changes) has always been a hot issue in ecological research (Rasmus and Simon 2012;Shrestha et al 2017;Kern et al 2020;Guo et al 2020c). Remote sensing spectral information offers many advantages, such as good temporal and spatial continuity, not being limited by geographical conditions, strong currency and so on (Rasmus et al 2009;Sandra et al 2015).…”
