中文摘要	向海湿地位于半干旱的吉林西部平原区,特殊的地理位置和水文条件决定了湿地处于动态变化之中.在自然和人为驱动影响下,系统结构和功能发生明显的退化趋势,湿地面积缩小、调节功能削弱,区域荒漠化发展迅速.通过对湿地发育的环境背景条件分析,剖析了湿地退化的现状及驱动机制,水陆界面的脆弱性是湿地退化的环境背景条件,而气候干旱化、上游水的大量截流、水利工程设施及土地资源的不合理开发利用等自然、人为因素的耦合作用,加速了湿地的退化过程.基于湿地退化的现状和驱动机制,河流湿地退化的恢复必须从湿地的水文功能出发,考虑水资源的循环和转化,制定水资源综合利用方案及生态技术和生态工程措施.
英文摘要	Xianghai wetland is located in the west of Jilin Province with a semi-arid climate. The special geographical location and hydrographical condition makes the wetland water environment stand in the dynamic changing. Under the natural and artificial influences? the structure and function of the wet-land appear obviously degraded, such as, the area shrink, the system function become weak which re-sults in the rapid desertification. This paper have discussed the present state and driving mechanism of the environment degradation of this wetland based on the environmental background. The fragible inter-face between water and soil is the natural background, but the climate aridity, upstream water intercep-tion , hydraulic engineering and irrational land-use activities are the inducing factors to promote the wet-land degradation. Finally comprehensively considering the present state of degradation and its driving mechanisms, a comprehensive water resources management plan and an ecological technology and engi-neering were put forwards to recover the degraded wetland.
