基于遥感技术的环巢湖区域湿地景观格局及可持续设计
|
摘要
巢湖流域湿地资源是重要的自然资源,是长三角城市群的天然后花园,对巢湖流域湿地资源的可持续开发迫在眉睫。基于此,以环巢湖区域为研究对象,对巢湖市2017年航空影像图进行人工目视判读,根据地理信息系统软件VIEW GIS技术对研究区的湿地要素进行数字化,形成不同的图层,并编辑绘制环巢湖区域的湿地信息分布图。研究发现,研究区湿地景观斑块主要集中在巢湖北岸,分布不均匀,尺度变化范围大,小尺度的斑块所占比例高,破碎化严重。因此提出湿地景观合理开发利用的策略,为巢湖市湿地景观可持续发展提供依据。
The wetland resources in the Chaohu Lake Basin are important natural resources, and are the Tianhou Garden in the Yangtze River Delta urban agglomeration. The sustainable development of the wetland resources in the Chaohu Lake Basin is imminent. Based on this, the Huanchao Lake area was taken as the research object, and the aerial image of 2017 in Chaohu City was manually visually interpreted. According to the VIEW GIS technology, the wetland elements in the study area were digitized to form different layers, and edited and drawn. Wetland information distribution map in the area around the Chaohu Lake. The study found that the wetland landscape patches in the study area are mainly concentrated on the north shore of Chaohu Lake, with uneven distribution and large scale variation. The proportion of small-scale plaques is high and the fragmentation is serious. Therefore, the strategy of rational development and utilization of wetland landscape is proposed to provide a basis for the sustainable development of wetland landscape in Chaohu City.
