The purpose of this article is to identify the effect of land use pattern on rainfall runoff and runoff sediment relations in Zichang Watershed of the Loess Plateau. From 1986 to 1997, many farmlan
The applicability of a non-point source pollution model—SWAT(soil and water assessment tools) in a large river basin with high sediment runoff modulus(770 t/km2 in the Yellow River) was examined. The
The large-scale upper circulations and merid-ional overturning in the upper layer of the South China Sea (SCS) with idealized bottom topography in winter and sum-mer are investigated. Simulations with
With the aid of the Remote Sensing (RS) and Geographic Information System (GIS) technology, the eco-system pattern and fragility distribution maps of the 50-km-wide zone along the Qinghai-Tibet Railwa
Regional decadal precipitation reconstructions for the arid and semi-arid zones of northern China were established by the use of different palaeoclimate archives such as ice-cores, tree-rings, lake se
The topography data of the Zengmu Shoal and its adjacent area are acquired by the SeaBat-8111 multibeam system. The full survey covering over the Zengmu Shoal area gives us new knowledge about the ar
MANDELBROT enunciated the uncertainty of the length of a coastline in his paper "How long is the coastline of Britain?" published in Science in 1967. The fractal concept was presented for the first ti
Groundwater in Changchun City, Jilin Province of China tends to be influenced by human activities. Chemical types of groundwater were detected in both shallow and deep groundwater were: HCO3--Ca2+ and
