The karst geo-ecosystems are fragile environments. largest region in the world is located southwestern China, within which Guangxi province one of main areas. Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.), an evergreen species, important fast-growing timber tree southern China. In present study, we examined genetic diversity and spatial differentiation sampling localities around landform ...

Abstract Under the stress of global change, rocky desertification has become a serious environmental problem in Karst Mountain area. At present, few remote sensing monitoring research works on based feature space model have been conducted and reported. In this study, Albedo-LST index point-point proposed, subsequently spatio–temporal evolution pattern driving mechanism Dafang district from 1986...

Development of robust reclamation designs would require understanding the relative effects climate change on water budget reclaimed Athabasca oil sands landforms (Alberta, Canada). A surplus is critical to sustain pit lakes and periodically freshen localized surface ponds within closure landscape. In this study, four hypothetical future scenarios were developed from statistically downscaled RCP...

Topography affects the intensity and spatial distribution of precipitation due to orographic lifting mechanisms and, in turn, influences prevailing climate vegetation distribution. Previous modelling studies on impact landform evolution have considered bare soil conditions. However, research effect changes regimes induced by elevation gradients (particularly aspect-controlled semi-arid ecosyste...

This study was part of a project designed to simulate the long-term landform equilibrium rehabilitated mine site. The utilized event Fine Suspended Sediment (FSS) fluxes in receiving stream following rainfall as an indicator stability. aim this use HEC-HMS determine sediment and discharge quantity upstream how it affects downstream development catchment landform, terms changes geomorphology. Th...

This study was carried out to model the ecosystem services, i.e., habitat quality, carbon storage, nutrient export, and soil export using InVEST software quality through integrated index across Shoor River basin, southwestern Iran, as well their relationships landscape metrics Pearson’s correlation ordered least square regression. The interactions between services efficiency, fragmentation were...

Surface elevation is a critical data for geo-science study. As far as some regions with rapidly-changing in landform, analyzing the surface elevation of different periods help provide scientific basis for regional economic & social sustained development. Jiangsu coast is force tide zone, and the complicated sediment dynamical environment, gently rolling tidal-flat landform, huge spatial differe...
