Using the radial basis function network model to assess rocky desertification in northwest Guangxi, China

, 2020
Karst rocky desertification is a progressive process of land degradation in karst regions in which soil is severely, or completely, eroded. This process may be caused by natural factors, such as geological structure, and population pressure leading to ...

Rocky desertification in Southwest China: Impacts, causes, and restoration

, 2014
Rocky desertification, which is relatively less well known than desertification, refers to the processes and human activities that transform a karst area covered by vegetation and soil into a rocky landscape.

Rocky desertification in Guangxi karst mountainous area: Its tendency, formation causes and rehabilitation

, 2008
By using Landsat TM/ETM digital images, the temporal-spatial structure characteristics and developing principle of rocky desertification in Guangxi karst mountainous areas were monitored from mid-1980s to later 1990s.

Responses of soil physical and chemical properties to karst rocky desertification evolution in typical karst valley area

IOP Conference Series: Earth and Environmental Science, 2018
In order to reveal the differences of soil physical and chemical properties and their response mechanism to the evolution of KRD. The characteristics of soil physical and chemical properties of different grades of KRD were studied by field sampling method to research different types of KRD in the typical karst valley of southern China. Instead of using

Response of preferential flow to soil − root − rock fragment system in karst rocky desertification areas

The response of preferential flow to the soil − root − rock fragment systems is essential for understanding the eco-hydrological processes in karst rocky desertification (KRD) areas.

Classification of rocky desertification degrees and analysis of driving factors in typical karst regions

Frontiers in Environmental Science
Rocky desertification is a major ecological problem in karst regions, driven by the combined effects of natural conditions and human activities. To investigate its spatiotemporal evolution and driving mechanisms, this study constructed a two-dimensional ...
