Poplar plantation is the most dominant broadleaf forest type in northern China. Since the mid-1990s plantation was intensified to combat desertification along China's northwestern border, i.e., within Inner Mongolia (IM). This evoked much concern regarding the ecological and environmental effects on areas that naturally grow grass or shrub vegetation. To(More)
Accurately quantifying evapotranspiration (ET) is essential for modelling regional-scale ecosystem water balances. This study assembled an ET data set estimated from eddy flux and sapflow measurements for 13 ecosystems across a large climatic and management gradient from the United States, China, and Australia. Our objectives were to determine the(More)
The semi-arid grasslands in Inner Mongolia (IM) are under increasing stress owing to climate change and rapid socio-economic development in the recent past. We investigated changes in land cover/land use and landscape structure between 1992 and 2004 through the analysis of AVHRR and MODIS derived land cover data. The scale of analysis included the regional(More)
The objective of this paper was to determine whether CO2 exchange rates could be used as an indicator for determining the state of development and species or functional composition of biological soil crusts in di€erent successional stages. We quanti®ed the CO2 exchange rates, i.e., CO2 assimilation and respiration, in samples from di€erent microhabitats at(More)
Aims Evapotranspiration (ET) is a key component of water balance and is closely linked to ecosystem productivity. In arid regions, large proportion of precipitation (PPT) is returned to the atmosphere through ET, with only a small amount available to plants. Our objective was to examine the variability in ET–soil water relationship based on a set of(More)
We investigated the variability of soil respiration and several potential regulatory factors and modeled their interrelationships from May to August over a 5-year period in oak forests subjected to alternative harvesting treatments as part of the Missouri Ozark Forest Ecosystem Project (MOFEP). Treatments included even-aged management (EAM), uneven-aged(More)
Understanding the regulation of ecosystem ET is crucial to comprehend present and potential future vegetation and water availability in arid environments. We compared ET data from eddy-covariance flux measurements in two semiarid shrub-dominated ecosystems. Located in the Kubuqi Desert (KD, Inner Mongolia, China) and the Sierra Madre (SM, Wyoming, USA), the(More)
