. Long term development depends on improved water supply by the transfer of water from South China to the North, regulation of flow on the rivers Huanghe, Huaihe, and Haihe, and soil conservation in the upper reaches. (TNC).

Remote sensing monitoring on regional crop water productivity in the Haihe River Basin
This article examines crop water productivity (CWP) of winter wheat and summer maize from 2003 to 2007 in the Haihe River Basin based on large-scale evapotranspiration (ET) and crop yield obtained by remote sensing technology. Results show both

Change of the solar radiation and its causes in the Haihe River Basin and surrounding areas
The temporal and spatial variations of solar radiation and the cause of the change in solar radiation have been analyzed based on meteorological data from 46 national meteorological stations and aerosol index data from TOMS over the Haihe River

Spatial and temporal variability of daily precipitation in Haihe River basin, 1958-2007
In this paper, the precipitation data from 30 weather stations (WS) for 1958–2007 and 248 rain gauges (RG) for 1995–2004 in the Haihe River basin are examined and compared using linear regression, 5-year moving average, Mann-Kendall trend analysis

Environmental and ecological water requirements of a river system : a case study of the Haihe-Luanhe river system
Cette étude a pour but de définir la quantité d'eau minimum qui doit être maintenue dans les masses d'eau naturelles pour conserver leurs fonctions écologiques. Elle s'applique à l'hydrosytème Haihe-Luanhe, province de Hebei en Chine où les besoins

of main regions in China have been investigated. The possible teleconnection between flood in the Yangtze River and the Haihe River valleys in 1991 and the volcanic eruption of Mt Pinatubo in June of 1991 has been also examined.

Nearly 90 alluvial rivers are involved in this study, located in different natural zones in China, and include the Yellow River, Yangtze River, Haihe River, Huaihe River, Liaohe River, Songhuajiang River and Pearl River and their tributaries. When
