Abstract

Water is main constraint factor for eco-environmental security in arid and semi-arid area and plays an important role on ecosystem stability. Water development in arid and semi-arid regions affected ecosystem directly. The eco-environmental problems were summarized including river runoff declining by surface water development, groundwater declining and groundwater exhaustion cone caused by groundwater development, vegetation degradation caused by over development of water resources, soil salinizaiton caused by irrational irrigation methods and landscape pattern transformation caused by water and soil development, analysis are basic supply for study on relationship between water and eco-environment and restoration measure for eco-environmental protection. The article also suggested that different groundwater development measure should be taken for farmland, range and dune grass.
