Monitoring Vegetation Dynamic in Horqin Sandy Land from Spot Vegetation Time Series Imagery
The changes in the composition and distribution of vegetation represent one of the most main sources of systematic change on local, regional, or global scale. The temporal evolution of NDVI data strongly linked to changes in the state of the surface is regarded as an effective time window able to show the natural seasonal variations. This study investigated vegetation change between 1998 and 20...
متن کاملWind-sandy Environment and the Effects of Vegetation on Wind Breaking and Dune Fixation in Horqin Sandy Land, China
Horqin Sandy Land is located in northeast China (4241’-4515’N, 11835’-12330’E). The wind-sand topography in Horqin Sandy Land can be described as two series--sand deposition and wind erosion. Wind is the natural force for the formation of wind-sandy environment, under windsandy environment, the wind erosion processes such as sand drifting, dust-storm, etc. occurred frequently because of the fre...
متن کاملAnalysis of Water Resources in Horqin Sandy Land Using Multisource Data from 2003 to 2010
Over the past four decades, land use/land cover (LU/LC) change, coupled with persistent drought, has resulted in the decline of groundwater levels in Horqin Sandy Land. Accordingly, this study quantifies changes in LU/LC and groundwater storage (GWS). Furthermore, it investigates the effects of LU/LC changes on GWS. GWS changes are estimated using Gravity Recovery and Climate Experiment (GRACE)...
متن کاملClassification of Land Use on Sand-Dune Topography by Object-Based Analysis, Digital Photogrammetry, and GIS Analysis in the Horqin Sandy Land, China
Previous field research on the Horqin Sandy Land (China), which has suffered from severe desertification during recent decades, revealed how land use on a sand-dune topography affects both land degradation and restoration. This study aimed to depict the spatial distribution of local land use in order to shed more light on previous field findings regarding policies on a broader scale. We perform...
متن کاملEffects of environmental factors on genetic diversity of Caragana microphylla in Horqin Sandy Land, northeast China
Caragana microphylla (Leguminosae) is a dominant climax semishrub species in northern China. We evaluated genetic variation within and among populations sampled from three different environmental gradients in Horqin Sandy Land in northern China using intersimple sequence repeats markers and investigated the possible existence of relationships between genetic diversity and environmental factors....
