Large scale rocky desertification reversal in South China karst
Progress in Physical Geography: Earth and Environment, 2022 The karst area in southwest China is, in recent decades, one of the world’s regions with the fastest vegetation growth and increase in aboveground biomass. The improvement in the ecological conditions within this region can, to a large extent, be attributed to ecological protection projects.

Karst rocky desertification progress: Soil calcium as a possible driving force
Science of the Total Environment, 2019Karst rocky desertification is a severe irreversible ecosystem failure. The karst ecosystem is so fragile that it is vulnerable to environmental changes, degrading into rocky desertification. Prior studies revealed the potential connections between the soil bacterial community, the edaphic properties and the aboveground vegetation cover in the karst ...

Karst rocky desertification in southwestern China: geomorphology, landuse, impact and rehabilitation
Land Degradation and Development, 2004AbstractKarst rocky desertification is a process of land degradation involving serious soil erosion, extensive exposure of basement rocks, drastic decrease in soil productivity, and the appearance of a desert‐like landscape. It is caused by irrational, intensive land use on a fragile karst geo‐ecological environment.

Rocky desertification exponential model in Karst area
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012It was noticed long time ago that Karst rocky desertification is gradually developed into the third-largest ecological problem. Remote sensing is mostly used in the research of Karst desertification. However, the previous research used original imagery, so it cannot effectively interpret the characteristic of rocky desertification.

Implication of different humic acid fractions in soils under karst rocky desertification
Catena, 2019 Karst rocky desertification, a kind of intense soil degradation, has become an urgent environmental issue in the karst region of southwest China. It was found that limestone soil, a typical soil of the karst region, is more vulnerable to karst rocky ...

Causes and control measures of the karst rocky desertification in chongqing karst mountain area
2011 International Conference on Electrical and Control Engineering, 2011Chongqing is one of the carbonate rocks distribute most widely and the Karst develop strongest provinces, especially in Karst Mountain area, its rocky desertification area covers 8557.45km2, accounting for 92.45% of the city's. Therefore, as one of the key cities in Western Development, the cause and control measures of the Karst Mountain area plays a ...

Estimate ecological indicators of karst rocky desertification by spectral unmixing algorithm
SPIE Proceedings, 2013Coverage rates of vegetation and exposed bedrock are two key indicators of karst rocky desertification (KRD) environments. Based on spectral unmixing algorithm, abundance of vegetation and exposed rock were retrieved from the hyperspectral Hyperion image.
