Abstract Oases soils in northwestern China are used widely for agricultural production, but low soil moisture and fertility necessitate high volumes of irrigation and fertilization, with significant losses of water via evaporation and nitrogen via denitrification. The dynamics of denitrifying communities and their

Land exploitation resulting in soil salinization in a desert–oasis ecotone
CATENA, 2013Abstract Understanding the process of agricultural land expansion and its impact on soil properties is crucial for land management and environmental health. A desert–oasis ecotone is typically located between an oasis at the lower reach of inland rivers and neighboring desert in arid regions, and acts as an interactive zone between irrigated farmland

A multivariate analysis of desert-oasis ecotone vegetation in Fukang with 55x42 (plots x species) species matrix,55x4 environment matrix and 55x5 spatial coordinates surveyed in Fukang is presented. The results show:1) eight communities are identified from the 55 plots (Haloxylon ammodendron desert, Reaumuria soongorica +Haloxylon ammodendron desert ...

The ecological environment of the Gurbantünggüt desert-oasis ecotone is extremely fragile. Ephemeral plants are an important part of the ecosystem and play an essential role in maintaining the ecological stability of the ecotone. However, few studies have focused on the growth, soil quality and system sustainability of ephemeral plants in different ...

Changes in soil and vegetation with stabilization of dunes in a desert–oasis ecotone
Ecological Research, 2015Abstract Revegetation of indigenous plants in a desert–oasis ecotone is an effective way of maintaining the stability of oases. Understanding the changes in vegetation and soil is crucial for restoration management.

AbstractMacropore flow not only provides a fast pathway for water and solute transport and increases the risks of water and nutrient loss but also enhances soil aeration and groundwater recharge. However, macropore flow characteristics in irrigated oasis soils subject to continuous crop cultivation are poorly understood.

AbstractConservation management for the water dependent desert‐oasis ecotone in arid northwest China requires information on the water use of the dominant species. However, no studies have quantified their combined water use or linked species composition to ecotone transpiration.

AbstractUnderstanding the impacts of different land‐uses on soil microbial communities is essential for maintaining soil health and sustainability in a desert‐oasis ecotone. Information on the microbial community composition of reclaimed soils under different land‐use types after several decades of reclamation are limited.

The effect of hydrologic process changes on NDVI in the desert-oasis ecotone of the Hexi Corridor
Science China Earth Sciences, 2014In the arid inland river basins of northwestern China, human activities control almost all the surface hydrologic processes. The potential effects of these altered hydrologic processes are gradually becoming clear, especially since the 2000 implementation of the integrated water resources management projects in the Shiyang River, the Heihe River, the ...

Dryland vegetation forms a "fertile island effect" due to water and nutrient retention. However, there has been little research on the mechanism underlying C-, N-, P-accumulation and overall fertile island at the community level. We therefore presented the systematic investigation on this issue through the survey in desert-oasis ecotone.
