Quantitatively revealing the response of carbon stocks to land use change (LUCC) and analyzing vulnerability ecosystem stock (ECS) services are great significance for maintaining cycle ecological security. For this study, China’s Guizhou Province was study area. Land data in 2000, 2010, 2020 were selected explore impacts LUCC on multiple scenarios by combining PLUS InVEST models then ECS services. The results show that forest plays an important role improving karst plateau mountainous areas....
In the southwest karst areas of China, changes in overlying vegetation due to ecological restoration cause considerable carbon sequestration (CS). Assessing CS potential this is crucial for promoting optimization and regulation regional restoration(VR) policies. This study based on net primary productivity, maximum coverage average coverage. Using VR effectiveness index (Ej) quantitatively evaluate spatiotemporal characteristics effectiveness, quantifying pattern using photosynthetic model,...
Exploring the evolution of livelihood patterns farm households relocated for poverty alleviation in three prefectures Guizhou Province, China, can provide a theoretical basis and practical value achieving sustainable livelihoods ethnic minority areas. This study took autonomous as research area. The types pathways households’ were divided using 355 tracking monitoring data from four phases livelihoods. characteristics changes their “before relocation” to 2021 analyzed. An indicator system...
Abstract In southwestern China karst rocky desertification (a process of land degradation involving serious soil erosion, extensive exposure basement rocks, drastic decrease productivity and the appearance a desert‐like landscape) results from irrational use on fragile, thin soil. Soil particles in Guizhou plateau were accumulated predominantly residues left behind after dissolution carbonate thickness layer is related to amount argillaceous substances lost rock. This paper examines spatial...
The relocation of local residents from ecologically vulnerable areas, with the aim alleviating poverty through spatial displacement, often referred to as Poverty Alleviation Relocation (PAR), is recognized a promising strategy tackle challenges 'spatial traps.' Nevertheless, current quantitative research regarding extent PAR's impact on ecological restoration remains limited. This study focuses Guizhou Province and aims quantify PAR region's carbon sink capacity. Upon examining alterations...
This study investigates the correlation between optical vegetation indices (NDVI, EVI, and DVI) in Xixiu Modern Efficient Vegetable Agricultural Demonstration Park using Sentinel-1A radar Sentinel-2A imagery.Results show that VH back-scattering coefficients exhibit most significant with across time periods, while VV, RVI, CR weaker or inconsistent correlations. Landscape shape index (LSI) patch size significantly influence these relationships, larger LSI sizes enhancing VH, NDVI/DVI.
Understanding the complex relationships among ecosystem services (ESs) is crucial for their joint management, particularly in vulnerable karst areas where ES dynamics are intricate. This study, focusing on Nanpan and Beipan River Basin (NBPRB), examines seven key ESs—food supply (FP), water (WS), soil retention (SR), carbon storage (CS), purification (WP), habitat quality (HQ), landscape aesthetics (LA)—over 1985-2020, to analyze spatiotemporal trends trade-offs synergies sustainable...
ABSTRACT Microhabitats, caused by the action of dissolution and soil erosion at different slope positions, are manifestations rocky desertification in Karst areas Southwest China. They play a significant role ecological restoration karst landscape changing hydrological processes via affecting vegetation properties as well erodibility. Nevertheless, few studies have been conducted to investigate potential influences microhabitat types positions on Thus, this study was performed assess...
Abstract Natural dissolved organic matter (DOM) is ubiquitous in aquatic environments and an essential component the carbon cycle karst areas. To improve understanding of caves with heterogeneous hydrological processes, we examined spatiotemporal variability DOM composition further uncovered its source fate. Results may also provide insights into feedbacks to sinks regions. In this study, concentrations compositions DOM, partial pressure aqueous dioxide (pCO2), inorganic carbon, other...
Accurate crop classification is the basis of agricultural research, and remote sensing only effective measuring technique to classify crops over large areas. Optical in regions with good illumination; however, it usually fails meet requirements for highly accurate cloud-covered areas rainy regions. Synthetic aperture radar (SAR) can achieve active data acquisition by transmitting signals; thus, has strong resistance cloud rain interference. In this study, we designed an improved planting...
During the 13th Five-Year Plan period (2015–2020), Poverty alleviation relocation (PAR), led by Chinese government in karst regions of southwest China, aimed to cope with poverty and ameliorate ecological environment. Nevertheless, few research results have involved quantitative assessment effectiveness PAR. Moreover, studies on effects migration distinguished climatic factors other restoration projects concerning It remains unclear what extent PAR affects regional In order quantitatively...
Abstract Vegetation restoration in ecologically fragile areas has a significant carbon sequestration (CS) effect. However, it is usually difficult to achieve quantitative assessment at the regional scale for this part of human activity intervention. The Chinese government's ex‐situ poverty alleviation and relocation (EPAR) project relocated approximately 10 million people from with ecological environment urban centralized resettlement, which typical case weakened environmental intervention...
Rapidly and accurately extracting tobacco plant information can facilitate planting man-agement, precise fertilization yield prediction. In karst plateau of southern China, identification is affected by large ground undulations, fragmented areas, complex diverse habitats uneven growth. This study took a area in Gui-zhou Province as the research object used DJI UAVs to collect UAV visible light images. Considering plot fragmentation, size, presence weeds shadow masking, this was classified...
Guanling-Zhenfeng County, a microcosm of the ecologically fragile karst area in southwest China, experiences rapid population growth and urban expansion which intensifies land use transformation ecological landscape fragmentation. Exploring spatiotemporal characteristics fragmentation its causes County is great significance maintaining stability ecosystem protection areas. In this study, comprehensive index (FI), geographic probe, multi-scale geographically weighted regression (MGWR), PLUS...
