Abstract :
[en] This paper describes the use of satellite imageries and GIS data for identifying key environmental characteristics of Binh Thuan Province in south central Vietnam and for detecting the major changes patterns within this region. Landsat TM (1990) and Landsat ETM+ (2002) imageries were used to classify the study area into seven land use and land cover (LULC) classes. A post-classification comparison analysis was used to quantify and illustrate the various LULC conversions that took place over the 12-year span of time. Results showed that a steady growth in population has caused extensive changes of land cover throughout the area. The maps also indicate that the loss of woody land (forest) and the extension of wetlands (irrigated area), combined with built-up encroachment, remains one of the most serious environmental problems facing the Binh Thuan Province today. The post-classification change detection analysis showed that critical habitats accounted for nearly 38.5% of the intensive study area between 1990 and 2002 while 61.5% remained stable. Results also showed over the 12-year span, approximately 1151.2 km² (115.120 ha) forest were converted respectively to brush, irrigated area (wetlands), cropland and built-up. This is an overall average decrease of 9594 hectares of forested area per year. Throughout the study area, districts most affected by forest conversion to another land cover are: Bac Bihn (2798 ha/year), Than Linh (2717 ha/year), Ham Thuan Nam (1601 ha/year) and Ham Thuan Bac (1524 ha/year). Based on the identified causes of these changes, we made policy recommendations for better management of land use and land cover.
