In order to explore the impact of development patterns on ecosystem service value(ESV)of oasis irrigation areas in the upper reaches of the Yellow River, Hongsibu District of Ningxia was selected as the research area. Based on Landsat TM and GF-2 remote sensing image data sources, the benefits and losses of ecosystem service value were quantitatively analysed by revising ecosystem service equivalent factors. The results showed that:(1)Since the first group of migrants from the southern mountainous areas of Ningxia moved into Hongsibu District at the end of 1998 and started the oasis development mode, the area of Hongsibu irrigated area continued to expand, reaching 5.17×104 hm2 by 2018, forming a desert oasis distribution pattern.(2)Oasis development significantly changed the land use structure in Hongsibu District, with the decrease of dry land, other grassland and unused land, and the increase of irrigated land, forest land and construction land, forming a ‘production-ecological' spatial pattern with oasis as living space and production space, in addition to surrounding ecological space.(3)From 1990 to 2018, ESV of Hongsibu District increased from 1.151×109 yuan to 2.267×109 yuan, which was mainly due to the expansion of forest, grassland, water and other ecological land. Each single service value showed a rising trend, and the ecological construction achieved remarkable results.(4)The total amount of ESV in Hongsibu District showed obvious stage characteristics, among which, decreased from 1990 to 2000, and then continued to increase. From 1990 to 2000, the expansion of dry land resulted in the imbalance of forest, grassland, useable land, ecological degradation and ESV loss of 2.9×107 yuan. From 2000 to 2018, ESV increased by 1.116×109 yuan, in which the rapid expansion of urban construction land was the main cause of ESV loss, while the expansion of forest, grassland and water area was the main cause of ESV increase. So Hongsibu District has achieved remarkable achievements in ecological construction in the process of oasis development, but there are also some cases of ESV loss due to development. In future development, it is necessary to further enhance the synergistic development capacity of the three aspects of society, economy and ecology.
