However, few studies have been done to consider seriously the relationship between LULC changes and the fragmentation of landscape. Hence, analysing the changes of LULC and landscape pattern helps revealing the interactions between anthropogenic factors and the environment, through which planning actions could be effectively supported. The present study aimed to examine these changes in the surroundings of Danang City, Vietnam from 1979 to 2009 based on Landsat Multi-Spectral Scanner (MSS), Landsat Enhanced Thematic Mapper Plus (ETM+) and ASTER satellite images. The Multivariate Alteration Detection (MAD) approach was employed for processing and postclassification change detection, from which key landscape indices were applied by using FRAGSTATS. The results showed that during the whole study period, there was a notable decrease of forestland, shrub, agriculture and barren while urban areas expanded dramatically. Further spatial analysis by using landscape metrics underlined the evidence of changes in landscape characteristics with an increase in total number of patches and patch density while the mean patch area decreased during the span of 30 years. Consequently, the landscape structure of Danang city became more fragmented and heterogeneous. 1. INTRODUCTION Urbanization is believed one of the most prevalent anthropogenic causes of the losing arable land, devastating habitats, and the decline in natural vegetation cover (Dewan and Yamaguchi, 2009). As a consequence, rural areas have been converted into urban areas with an unprecedented rate and making a noted effect on the natural functioning of ecosystems (Turner, 1994). Consequently, a profound understanding of land use change is very important to have a proper land use planning and sustainable development policies (Braimoh and Onishi, 2007). According to Myint and Wang (2006), to fulfil such a sustainable urban development, urban and regional planners have to summarise from numerous decisions. However, these decisions must be extracted from huge data sources which represent physical, biological and social parameters of urban areas in the continued spectrum of spatial and temporal domains. Hence, it is important to have an effective spatial dynamic tool, which is used to understand urban land-use and land-cover change (LULC) for predicting future change. Compared with various methods used to collect land use data, remote satellite technologies has proven its capacity in providing accurate and timely information on the geographic distribution of land use, especially for regional size areas (Sun et al., 2009). With the support of Geographical Information Systems (GIS), satellite images can effectively estimate and analyse changes and LULC trends (Hathout, 2002). Due to the fact that the rapid LULC change of one certain area is the driving force of change in ecological environment, which is continuously transforming landscape structure, thereby a need for comprehensive assessing and analyzing the change in landscape at broad scales is required. Importantly, understanding the changes in spatial contribution of landscape pattern helps revealing the critical implication of complex relationship between anthropogenic factor and environment (Ning ef aL, 2010). To describe fragmentation and spatial distribution, a range of landscape metrics was calculated for each land use/cover class from satellite classification results by FRAGSTATS (Kamusoko and AniYa, 2006). After the adoption of the “DOI MOI” policy in economy of the national assembly in 1986, Danang city has developed in many aspects. In addition, it was separated from Quang Nam Province in 1997 and has officially become an administration unit that directly belongs to the government. Since then, Danang city has asserted as the important position in nation level and the crucial factor of the main region economy of Middle area. This has caused the incessant land use/cover change in Danang for over past 20 years. Through exploring the land use map extracted from satellite data of different periods, the aims of the present study were to detect, quantify and characterise the changes of land use/cover and landscape fragmentation in Danang region. 2. STUDY AREA Danang city is located in Middle Central of Viet Nam, between the 15°55”19” to 16?13'20"N and 107?49'11" to 1089?20'20"E (Figure 1). It is a long-stretching narrow region and well known as a dynamic city of the Key Economic Zone in central Viet Nam. The area consists of hills and mountains in the northwest and the Eastern Sea in the east. The altitude varies from 400m to 1524m above sea level; next to is the upland with low mountains and the delta takes % areas in the southeast; it covers an area of 1,283.42km? including Hoang Sa island district of 305 km’.
