Evolutionary trends of drought under climate change in the Heihe River basin, Northwest China
The present paper focused on the analysis of drought in the Heihe River basin based on daily precipitation data observed at 13 weather stations covered from 1961 to 2010. The spatial and temporal variation of drought was estimated by means of the Standardized Precipitation Index (SPI), linear regression analysis and inverse distance weighted analysis. The SPI series on 1-month, 3-month, 6-month...
متن کاملAnalysis of Agricultural Land Use Change in the Middle Reach of the Heihe River Basin, Northwest China
The Heihe River Basin (HRB) is the second largest inland river basin in arid Northwest China. The expanding agricultural irrigation, growing industrialization, and increasing urban development in the middle reach have depleted much of the river flow to the lower reach, degrading the corresponding ecosystems. Since the enactment of the State Council of China's new HRB water allocation policy in ...
متن کاملHydrological Impacts of Land Use Change and Climate Variability in the Headwater Region of the Heihe River Basin, Northwest China
Land use change and climate variability are two key factors impacting watershed hydrology, which is strongly related to the availability of water resources and the sustainability of local ecosystems. This study assessed separate and combined hydrological impacts of land use change and climate variability in the headwater region of a typical arid inland river basin, known as the Heihe River Basi...
متن کاملEvaluating Impacts of Industrial Transformation on Water Consumption in the Heihe River Basin of Northwest China
Growing water scarcity is one of the central challenges for sustainability in China, given its burgeoning industry and huge population, especially in the arid and semi-arid inland river basin where precipitation is very limited. Industrial transformation is an important engine of economic growth, which is required to be implemented by governments at all levels in China. Economic models have gen...
متن کاملEconomic Valuation of Ecosystem Service in the Middle Basin of Heihe River, Northwest China
The ecosystem service concept is becoming more and more acknowledged in science and decision-making. Taking an economic valuation approach, we quantified the economic value change of ecosystem services for different land use types in the middle basin of Heihe River, Northwest China. Eight ecosystem services indicators were selected: raw materials production, crop production, gas regulation, hyd...
