摘要
以鸭绿江口滨海湿地保护区1995年和2010年两期遥感影像为基础数据,进行景观格局指数计算,对研究区景观格局的变化特征进行分析。结果表明:1995—2010年,保护区天然湿地的面积减少了19.58 km2,其中滩涂面积大量缩减;景观斑块数(NP)由1995年的2 177块增加到2010年的2 928块,增加了34.50%,表明东港市滨海湿地的景观破碎化程度越来越严重。滨海湿地景观的变化同时受到自然因素和人为因素的影响。
The calculation of landscape pattern index was made on the basis of two-period remote sensing image data on Yalu river mouth coastal wetland reserve in 1995 and 2010 so as to make analysis of the characteristics of landscape pattern in the study area. The results show that the area of the protected areas of natural wetlands decreased by 19.58 km2 from 1995 to 2010, of which, the tidal flats area was greatly reduced;the number of landscape patches （NP） increased by 34.50%from 2 177 in 1995 to 2 928 in 2010, which sug-gests that the coastal wetland landscape fragmentation of Donggang city is becoming increasingly serious. The changes in coastal wetland landscape at the same time are under the influence of natural factors and human factors.
