英文摘要Complex landforms, miscellaneous climates, and enormous populations have influenced various geophysical phenomena in china, which range from water depletion in the underground to retreating glaciers on high mountains and have attracted abundant scientific interest. this paper, which utilizes gravity observations during 2003-2014 from the gravity recovery and climate experiment (grace), intends to comprehensively estimate the mass status in 16 drainage basins in the region. we propose a multibasin inversion method that features resistance to stripe noise and an ability to alleviate signal attenuation from the truncation and smoothing of grace data. the results show both positive and negative trends. tremendous mass accumulation has occurred from the tibetan plateau (12.1 +/- 0.6 gt/yr) to the yangtze river (7.7 +/- 1.3 gt/yr) and southeastern coastal areas, which is suggested to involve an increase in the groundwater storage, lake and reservoir water volume, and the flow of materials from tectonic processes. additionally, mass loss has occurred in the huang-huai-hai-liao river basin (-10.2 +/- 0.9 gt/yr), the brahmaputra-nujiang-lancang river basin (-15.0 +/- 1.1 gt/yr), and tienshan mountain (-4.1 +/- 0.3 gt/yr), a result of groundwater pumping and glacier melting. areas with groundwater depletion are consistent with the distribution of cities with land subsidence in north china. we find that intensified precipitation can alter the local water supply and that grace can adequately capture these dynamics, which could be instructive for china's south-to-north water diversion hydrologic project.
