基于3S的闽江下游湿地景观空间分异研究

利用RS,GPS,GIS等技术手段,以闽江下游地区作为研究区域,选取景观多样型、优势度、均匀度、破碎度和分离度等指标,分析研究了闽江下游地区湿地景观的空间分异特征.结果显示,在沿海、近海和内陆地区之间,各类指标在地域空间上存在着明显的差异性;闽江下游地区湿地景观空间格局受到了地貌的支配;近海和海岸湿地具有比河湖湿地、人工湿地更高的生态功能与价值,是闽江下游地区湿地景观构成的核心.

Study on spatial patterns for wetland landscape in the lower reaches of the Minjiang river based on 3S

Researched the patterns and heterogeneity characteristics in the lower reaches of the Minjiang river wetland through landscape diversity,dominance,evenness,fragmentation and isolation,with the help of RS,GPS and GIS.The results shown that there are obvious differences in region space among coastal counties,island counties and inland counties,spatial patterns in the lower reaches of the Minjiang river wetland landscape are dominated by landform,costal wetland has more ecological functions and values than river and artificial wetland and it becomes the core of the structure in the lower reaches of the Minjiang river wetland landscape.
