The analysis of the landscape fragmentation in Dongguan could promote the sustainable development of its eco-environment,society and economy.Guided by the theory of landscape ecology,various landscape indices,including patch number,mean patch area,fragmentation index,fractal dimensions,boundary density,patch density,landscape diversity,landscape dominance and landscape fragmentation were selected to analyze the evolution features of landscape fragmentation in Dongguan.The research results revealed that the construction land kept intruding and assimilating farmland and natural landscape,the landscape patch number of study area was on the increase and the mean patch area reduced fast,so the landscape fragmentation degree of Dongguan was aggravated.After 1995,the land use speed slowed down,which indicated the study area started to focus on holistic development of city after drastic expansion.
