Special Issue Information

Dear Colleagues,

The arid regions cover 41% of the global land surface and support about 38% of the world’s population. The ecosystems in arid areas mainly include savanna, shrubs, grasslands, and deserts, and are highly vulnerable to water scarcity, floods, droughts, and desertification under ongoing climate change and human activities, probably leading to dangerous ramifications for the water–food–energy nexus, livelihood and wellbeing of their populations. Therefore, understanding the current advances in ecohydrology sciences in the arid regions is very important and necessary to optimize water resources usage, maintain ecological security, and realize the sustainable development of these regions.

This Special Issue aims to investigate the advances in ecohydrological processes in the arid regions and the responses and feedbacks of ecosystems to climate change, droughts, water conveyance, etc. Similarly, the investigations on water resources management, ecological restoration, degradation, and ecological stress are also essential to promote a stable ecosystem condition.

Submissions will address one or more of the following issues, and closely related topics are also welcome:

  • Ecohydrological processes in the arid regions;
  • Responses and feedbacks of vegetation to climate change and extreme events;
  • Ecological responses to regional/local water conveyance projects;
  • Evaluation of ecosystem security in the arid regions;
  • Impact of climate and water resource changes on ecosystems;
  • Land use changes in arid and semi-arid environments;
  • Water resources management and water use efficiency in arid areas;
  • Function of arbuscular mycorrhiza on soil and ecological processes;
  • Role of hydraulic redistribution in water availability and ecosystem function;
  • Degradation and restoration of ecosystems in arid regions; and
  • Satellite observations of ecohydrological process in arid regions.

In this study, based on the DEM, we extracted the drainage networks and watersheds of the Daqing River with ArcGIS, investigated the basin characteristics and the differences in their spatial distributions and analyzed the relations of the drainage density with some surface conditions and how the drainage density influenced the water yield. The results suggested a power function between the mainstream length and drainage area, showing that with the increase in basin area, the basins became longer. The result of the power function between the relief and drainage area with negative exponent values means the relief changed more slowly with increasing basin area. The values of the circularity ratio and elongation ratio indicate that the basin shape of the mountain watersheds in the Daqing River was narrow and predisposed to flooding during periods of heavy rainfall. The orders of the streams in the mountain watersheds ranged from five to seven. The average bifurcation ratio of those nine mountainous watersheds reveals the order of the u + 1 rivers in each basin of the Daqing River was on average 4 times larger than that of order u rivers. The drainage density (Dd) was high in the north and low in the south of the Daqing River. Rainfall was negatively correlated with drainage density, but the correlation between them was not significant at the 0.05 level. Drainages developed in places with poor vegetation cover. The drainages in the southwest, north and west developed considerably, while drainages in the east and southeast did not develop much. Yet, the available data showed the impact of the watershed area, elongation ratio and drainage density on the water yield was not significant. In contrast, there was a significant positive correlation between channel slope and the water yield modulus. The hypsometric integrals and the relation between drainage density and hypsometric integral suggest that the landform evolution of the mountain basins along the Daqing River were in the old stage with no further increase trend of drainage density in the future.
