摘要
以遥感影像为依据进行现地核实,对昭阳区湿地资源进行了调查。调查结果,昭阳区境内湿地有河流、湖泊、沼泽、人工湿地4种类型,共140个斑块,面积4 940.15 hm^2;湿地植物类型有6个;湿地野生动物有黑颈鹤、白头鹤、金雕、苍鹰等310余种;分析湿地特点及分布规律。当前昭阳区湿地资源没有统一管理机构,湿地生物多样性降低,系统抗干扰能力弱,还未实行生态补偿。藉此提出相应建议。
This paper studied the wetland resources in Zhaoyang District based on the remote-sensing image and field investigation. The results showed that 4 types of wetland, including river, lake, marsh and constructed wetlands, with 140 patches and 4940.15 hm^2, were investigated, and 6 species of wetland plants and more than 310 species of wetland animals, including Grus nigricollis, Grus monacha, Aquila chrysaetos and Accipiter gentilis were discovered in Zhaoyang District. This paper analyzed the characteristics and distribution rules of wetland, and pointed out some problems on decentralized management, low biodiversity, week capacity of resisting disturbance and vacant eco-compensation. Aiming at these problems, some countermeasures were put forward.
