Microclimatic characteristics of the Heihe oasis in the hyperarid zone of China
The study area is located in the Ejin region of Inner Mongolia, in the lower reaches of the Heihe River. These desert riparian forests represent an important forest resource in arid desert environments. The study of the microclimatic characteristics
of the Heihe oasis will provide some basic data to understand the ecological functions of plant communities and to evaluate the environment benefit of their presence in the hyperarid zone. Furthermore, it will lay a scientific basis for the rational management

Since 2000, great changes in spatial-temporal distribution of water resources took place in the lower Heihe River. In order to objectively evaluate the influence of water regulation on the eco-environment, the changes of groundwater table, typical
vegetation, landscape types as well as East Juyan Lake have been analyzed in the lower Heihe River, by means of field surveys and remote sensing. These results indicate that there are obvious effects of water regulation on the eco-environment, which has been
improved toward sustainability in the lower Heihe River.

RS analysis of glaciers change in the Heihe River Basin, Northwest China, during the recent decades
This paper studied the glaciers change information using object-oriented information extraction technology in the Heihe River Basin (including Heihe River and Beida River) since 1960s to 2007/2011. 1:50,000 topographic map data, Landsat TM/ETM
+ remote sensing images and digital elevation model data were used in this research. Compared with other western mountain glaciers, glaciers retreat in the Heihe River Basin has a higher rate. Analysis of the 6 meteorological stations'annual average

Impacts of land use changes on groundwater resources in the Heihe River Basin
Based on 3 periods of remote sensing data from the 1960s and the long-term observed data of groundwater from the 1980s, the impacts of land use changes on the groundwater system in the middle reach of Heihe River Basin in recent 3 decades

Trans-border exchange between Russia and China : the case of Blagoveshchensk and Heihe
