摘要
为构建新的大天鹅栖息地,实现越冬期大天鹅的合理分布,在三门峡市黄河公园采用了地形整理、食物链构建等湿地生态修复技术构建了大天鹅的栖息地。结果显示:2015年11月到2018年2月,黄河公园大天鹅数量从无到有,最多达625只;黄河公园成为了大天鹅在三门峡库区夜栖地之一。利用GIS技术选择食物距离、道路距离、NDVI等因子构建逻辑斯蒂方程作为栖息地评价模型,评价了黄河公园作为大天鹅越冬早期栖息地的适宜性。
In order to build a new habitat for whooper swans,and to realize the reasonable distribution of whooper swans during winter,this study constructed a whooper swans’habitat by adopting the wetland ecological restoration techniques such as topography and food chain construction inYellow River park of Sanmenxia.The results showed that from November 2015 to February 2018,the number of whooper swans increased from zero to 625 at most.The Yellow River park has also become one of the swans?nocturnal habitat in the reservoir area of Sanmenxia.This study uses the GIS-based geographical information technology to select the food distance,road distance,NDVI and other factors to construct the logistic equation as a habitat evaluation model and to evaluate the suitability of the Yellow River park as the early winter habitat for whooper swans.
