Long term effects of xerophytic shrub Haloxylon ammodendron plantations on soil properties and vegetation dynamics in northwest China

The xerophytic desert shrub Haloxylon ammodendron (C. A. Mey.) Bunge. is distributed naturally in Asian and African deserts, and is widely used for vegetation restoration in the desert regions of Northern China. However, there are limited long-term chrono-sequence studies on the impact of changed soil properties and vegetation dynamics following establishment of this shrub on mobile sand dunes. In...

HiWATER: Vegetation height product in the middle reaches of the Heihe River Basin (19 July, 2012)

In July 19, 2012 (UTC+8), the airborne LIDAR data is acquired in the foci area in the Heihe,middle reaches, which can provide high spatial resolution (m) and high precision (20 cm) of the surface elevation information. Based on airborne LIDAR data processing, the land surface DEM, DSM and point cloud density map were generated. By subtracting DSM and DEM directly, a Vegetation height product in t...

HiWATER: Land cover map in the Core Experimental Area of flux observation matrix

The dataset contains vegetation type in the middle reaches of the Heihe River Basin, which was used to validate products from remote sensing. It was generated from investigating the land cover strips of CASI during 2012.
Instruments: High-precision handheld GPS (2-3 m) and digital camera were used as main tools in the survey.
Measurement method: Hierarchical classification is applied based on CASI...
