- Abstract:
-
The northern mountainous area of Hebei Province as the water source of Beijing and Tianjin plays a vital role in ensuring the safety of downstream water. The focus of the study is on changes in eco-environment in the northern mountainous area of Hebei Province and effects of the change on transporting clean water to downstream. The data comprise land use in 1990 and 2009, precipitation from 1980 to 2009 and household survey in Dongbeigou Watershed where many environmental preservation projects were implemented. The results indicated that there was a huge progress in environmental construction with more than 50% land covered by forest; as the increase of vegetation cover, the intensity and frequency of soil erosion went down. By contrast, the available water resources declined due to the decrease of precipitation. The eco-water consumed by forest increased because of vegetation rehabilitation. In addition, the inhabitants in water source have not strong environmental protection sense and don’t realize the important position of water source. Non-point source pollution induced by high input of amount of chemical fertilizer is harmful to transporting water to downstream. Setting up the ecological compensation scheme is a good way to coordinate the conflicts between water source area and downstream.
