Characteristics and influencing factors of farmland abandonment in the karst rocky desertification area of Southwest China

open access: yesEcological Indicators
Owing to rocky desertification, farmland abandonment in karst areas is different from that in normal landforms. Aiming at the phenomenon of large-scale farmland abandonment in the karst region of Southwest China, this study investigated the ...

Microclimatic Influences on Soil Nitrogen Dynamics and Plant Diversity Across Rocky Desertification Gradients in Southwest China [PDF]

open access: yesPlants
Soil active nitrogen (N) fractions are essential for plant growth and nutrient cycling in terrestrial ecosystems. While previous studies have primarily focused on the impact of vegetation restoration on soil active nitrogen in karst ecosystems, the role ...

Remote Sensing Ecological Quality and Its Response to the Rocky Desertification in the World Heritage Karst Sites

open access: yesLand
Clarifying the spatial and temporal evolution characteristics of the ecological environment quality of World Heritage Karst Sites (WHKSs) and its response to different rocky desertification grades at spatial scales is crucial for the monitoring and ...

Estimating ecological indicators of karst rocky desertification by linear spectral unmixing method

open access: yesInternational Journal of Applied Earth Observation and Geoinformation, 2014
AbstractCoverage rates of vegetation and exposed bedrock are two key indicators of karst rocky desertification. In this study, the abundances of vegetation and exposed rock were retrieved from a hyperspectral Hyperion image using linear spectral unmixing method. The results were verified using the spectral indices of karst rocky desertification (KRDSI)

Extraction of Rocky Desertification Information in the Karst Area Based on the Red-NIR-SWIR Spectral Feature Space

open access: yesRemote Sensing, 2023
The complex topography, severe surface fragmentation and landscape heterogeneity of the karst region of southwest China make it extremely difficult to extract information on rocky desertification in the region.

The Response of Rocky Desertification to the Development of Road Networks in Karst Ecologically Fragile Areas

open access: yesInternational Journal of Environmental Research and Public Health, 2023
Frequent cross-regional communication makes road networks increasingly dense and has generated prominent human interference, thus resulting in the destruction of the landscape’s integrity and leading to changes in the functional processes of the habitat. In order to discuss the impacts of intense human activity brought by the road networks on the rocky

Differences in Fine Root Traits of <i>Quercus rehderiana</i> Between Rocky and Nonrock Desertification Forests in Southwest China. [PDF]

open access: yesEcol Evol
Fine roots (< 2 mm in diameter) play an important role in plants acquiring soil water and nutrient resources. Their morphological and chemical traits linked to resource strategies have received much attention in the world. However, whether the traits related to resource strategies are affected by environmental conditions or phylogeny is still unclear ...

Karst dissolution rates of carbonate rocks in north-south geographical boundary of China—the Qinba Mountain Area

open access: yesCarsologica Sinica, 2023
The karst area in the south of China is one of the three major karst distribution areas in the world. But the economic development of the karst mountainous area is severely restricted by the fragility of its environment and unreasonable disturbance of ...

Progress and Prospects of Research on Microhabitat Scale Characterization and Utilization in Chinese Karst Area. [PDF]

open access: yesEcol Evol
Karst regions exhibit ecologically fragile environments but host a rich diversity of microhabitats across spatial scales. Vegetation productivity and carbon sequestration patterns are intricately governed by subterranean microhabitat conditions. Microhabitat‐based technologies demonstrate transformative potential in reconciling human livelihoods with ...
