摘要
陕西三河湿地位于陕西关中平原的东缘,是典型的河流湿地。根据三河湿地发育的地貌、水文、植被、土壤、生物等自然背景特征,将湿地类型划分成系、类和种5个层次。在此基础上分析了三河湿地的演化,由于自然与人为因影响相互叠加,使湿地退化过程加速,针对目前湿地现状提出湿地资源保护与可持续利用的建议与对策。
Sanhe wetland, which is a typical riverine wetland, locates in east region of Guanzhong Plain in Shaanxi province. Based on the features of the key elements such as geomorphologic, hydrology, vegetation, soil and living beings, the types of Sanhe wetland were divided and the different evolution modes were analyzed.Sanhe wetland＇s degradation accelerates because of both natural and anthropogenic impacts. According to the situation of wetland,the suggestions and countermeasures of the protection and sustainable utilization of Sanhe wetland were put forward.
