盐城湿地建设项目对越冬水鸟生境的累积生态影响评价研究

选择盐城湿地的建设项目为研究对象.选取丹顶鹤、雁鸭类和鸻鹬类作为盐城湿地越冬水鸟的代表性物种,选取生境景观类型、土地占用以及人为干扰作为影响因子,利用ArcGIS分别做出三个影响因子对于越冬水鸟生境影响分布图,采用图形叠置法对各因子生境影响进行叠加.据此,以越冬水鸟适宜生境面积的变化来反映建设项目对于越冬水鸟的累积生态影响.并且提出设立鸟类监测救护站和栖息地补偿等生态措施来减少建设项目的影响.

Cumulative Ecological Impactof Construction Projects on Wintering Waterfowl Habitat in Yancheng Wetland

Construction projects were selected as the research object in Yancheng wetland. Red-crowned cranes,ducks and geese were selected as a representation of wintering waterfowls in thewetland of Yancheng. Habitat landscape, land use and human disturbance plays wereselected as influence factors. Three habitat factor maps about wintering waterfowls made by GIS technique were overlaid. Cumulative ecological impact of construction projectswas concluded by means of the change of suitable habitat area about wintering waterbirds. At the same time, some corresponding measures were raised to slow down the effect of construction projects, for example, setting bird monitoring and aid station and starting habitat compensation projects.
