Characteristics of land-use in river valleys of Taihang mountains area, Hebei Province.

Using the theory of landscape ecology, the land-use characteristics of main valleys are analyzed in 7 rivers of Taihang mountains area of Hebei Province. The results show that the valley land-use patterns of 7 rivers are similar despite that the river properties, landform characteristics and water situations are different from each other, and farmland occupies 50% - 80%, village 20% and forest land less than 10% of valley area. The land-use types increase from upstream to downstream. The land patches are relatively fragmented, and the number of land patch is 5 or 6 per 1000 meters valley. The reserved watercourse occupies 15% -30% of valley area in Fuping County, and no more than 10% in Yuanshi County.
