摘　　要：基于GIS技术和景观生态学理论,选用斑块密度指数、最大斑块指数、分维数、景观形状指数、景观优势度和均匀度等景观格局指数,分析东莞市自1988年以来的基于景观水平的空间格局特征变化。结果表明,珠江口两岸景观的破碎化程度加深,异质性在不断增加,空间结构趋于复杂化。Based on GIS and landscape ecology theory,choosing some landscape indexes such as patch density,density landscape fractal dimension,landscape shape index,landscape diversity,and dominance and evenness index,the spatial pattern change in the coastal area of Pearl River estuary was studied.The results showed that the land use changed with more fragmentation level,increasing heterogeneity and more complex structures.
