Seasonal Dynamics of Soil Multitrophic Biodiversity, Co‐Occurrence Network and Assembly Mechanisms Under Typical Vegetation Restoration Patterns in Karst Region

Land Degradation &Development, EarlyView.
ABSTRACT Previous studies often overlooked the dynamic effects of karst vegetation restoration on soil multi‐trophic biodiversity and the underlying community‐assembly mechanisms. To fill this gap, we performed a seasonal comparative analysis of soil biodiversity, co‐occurrence network architecture, and assembly processes across three representative ...

Study on the Present Situation and Cause of Formation of Rocky Desertification in Xichuan County [PDF]

, 2017
As the eco-environmental security guarantors for water source, Xichuan and its hydro-ecological condition play important roles in Middle Route Water Transfers Project from South to North. Via analyzing the soil, water quality, rock and vegetation et al.,

Variation of Vegetation Ecological Water Consumption and Its Response to Vegetation Coverage Changes in the Rocky Desertification Areas in South China.

PLoS ONE, 2016
Over the past several decades, rocky desertification has led to severe ecological problems in karst areas in South China. After a rocky desertification treatment project was completed, the vegetation coverage changed greatly and, consequently, increased ...

KARST ROCKY DESERTIFICATION ANALYSIS BASED ON HISTORICAL DISP DATA TAKE TWO REGIONS FOR EXAMPLE [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Karst rocky desertification (KRD) is used to characterize the processes that transform a karst area covered by vegetation and soil into a rocky landscape almost devoid of soil and vegetation.

Land Degradation Pathways of Open‐Pit and Underground Mining in Karst Regions: A Spatial Indicator Assessment

Land Degradation &Development, EarlyView.
ABSTRACT Mining in the karst regions of southwest China threatens ecosystem stability and accelerates land degradation. Regional evaluation rarely distinguishes between degradation pathways in open‐pit and underground operations, due to spatial heterogeneity and geomorphological confounding effects.

A novel-optimal monitoring index of rocky desertification based on feature space model and red edge indices that derived from sentinel-2 MSI image

Geomatics, Natural Hazards & Risk, 2022
Few studies of monitoring rocky desertification based on Sentinel-2 MSI image with higher spatial and temporal resolutions have been reported. In this paper, nine typical surface parameters that derived from Sentinel-2 MSI image including three red edge ...

Driving Mechanisms of Land Degradation Neutrality at the County Level and Zonal Strategies in the Yellow River's Key Ecological Region (Part II: Post‐Assessment Driver Analysis)

Land Degradation &Development, EarlyView.
ABSTRACT Achieving land degradation neutrality (LDN) is critical for sustainable socio‐ecological development; however, its practical implementation is often hindered by scale mismatches between assessments and administrative units, coupled with an over‐reliance on static drivers.

Low Soil Organic Matter Stability Exacerbates the Vulnerability of Karst Areas to Rocky Desertification

Land Degradation &Development, EarlyView.
ABSTRACT Karst rocky desertification represents a severe form of land degradation and has traditionally been attributed to geological and hydrological constraints. However, soil organic matter (SOM), a key regulator of erosion resistance, is highly responsive to management practices, yet its contribution to rocky desertification remains poorly ...

Correlation mechanism between rocky desertification degrees and slope position factors in karst mountainous area of southeast Yunnan

Carsologica Sinica
As a kind of land degradation phenomenon, rocky desertification is one of the main ecological problems in karst areas in Southwest China. The key to the effective control of rocky desertification is to explore the distribution law and influence mechanism

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...
