Abstract:

The sensitiveness of ecosystems to global change is an important aspect in global change research. Global change is featured as warming and drying climate in the North China Plain in recent years, which aggravates water crisis in the region. Specific hydrological condition is a major driving factor shaping wetland and its evolvement. Wetland ecosystem is, therefore, particularly important in this region. Since 1960, the water level and volume has declined, water area has shrunk, and biodiversity has decreased in Baiyangdian wetland. Natural factors, particularly climatic change, have played a decisive role in the process of wetland degradation; among them precipitation has significantly influenced the wetland. Climatic change has caused the variation of hydrologic characters of the wetland, the decrease of water supply, and the increase of water consumption. As a result, the wetland degraded. Human factors have intensified this trend to a certain degree.

Key words: climatic change, Baiyangdian, wetland, hydrologic characters
