基于ArcGIS的南昌市象湖湿地公园景观格局分析
Analysis of the Landscape Pattern of Xianghu Wetland Park in Nanchang City Based on ArcGIS
摘要
Abstract
The study takes Xianghu Wetland Park as the research object,tries to analyze the landscape pattern of the meso?and small?scale park,to provide a reference for the ecological planning of urban wetland park.The data of 9 types of landscape patches were extracted by ArcGIS software. The main research results show that:①the area,length and patch number of different landscape components are not balanced,the number of patches in the water landscape is the smallest,but the area is the largest,which accounts for 57.47％,the number of patches in the forest landscape is the largest,and the area accounts for 17.75％;②the five functional areas and nine landscape types constitute a unique pattern of park space;the corridor density is moderate,and the water patch,forest patch and open?forest patch are three dominant plaques;③the pattern of landscape pat?ches is simple and regular,and the spatial distribution pattern presents eight large types of small landscape pat?ches embedded in the large landscape patches,which forms a relatively complete green system and beautiful landscape;④the park landscape diversity index is 4.5765,the evenness index is 0.6066,the fragmentation in?dex is 3.9961,it is recommended to enhance the connectivity of the dominant landscape and pay attention to the balance of different landscape types in the future landscape conservation and construction.关键词
