| 摘 要： | 西北干旱半干旱区湿地包括自然湿地和人工湿地两大类型。在干旱半干旱环境背景控制下发育的湿地具有独特的特点。由于自然与人为因素影响相互叠加,使得湿地退化过程加速和复杂化,表现为湿地面积减小,湿地咸化、沙漠化、盐碱化,湿地生态系统受损,生态调节功能降低。针对目前湿地退化现状,加强我国干旱半干旱地区湿地的保护、恢复及生态系统重建,已成当务之急。

| Abstract: | Wetlands in the arid and semi-arid areas in northwest of China include natural and artificial ones.Wetlands have unique characteristics controlled by environment backgrounds of arid and semi-arid.Wetland's degradation accelerates and becomes complicated because of both natural and anthropogenic impacts.Wetland area reducing and wetland sandification result in the unbalance of wetland ecosystem and lower the ecological regulating function of wetland.According to the situation of wetland degradation,it is a task of top priority to strengthen the protection and recovery of wetland ecosystem in the arid and semi-arid areas of northwestern China. |
