Quantitative assessment of land use/land cover change through multi-temporal remote sensed data in Dien Bien province, Vietnam

Abstract

     Land use/land cover (LULC) change is one of the significant modifications in the socio-economic development process. Especially in moutainous areas - where the information about the temporalspatial characteristic changes of land resources is the basic tool for efficiently natural-resource monitoring, management and planning. Based on the use of remote sensing tools, the information on land use objectsis generally described the changes in the GIS environment. This study is used the object-based image classification in Dien Bien province in the period of 2002-2017. The characteristics of land use/land cover objects are expressed through the statistical results of 07 landscape metrics. The results described the increasing area of shrubland (90,770.58ha), agriculture (30,102.03 ha) and the declining of plantation forest (42,506.9 ha), natural forest (86,474.3 ha)which comes mainly from the rising demand for agricultural production. The landscape metrics of MPS, ED, TLA, NP, PD, LSI, PRD has demonstrated this modification. It is considered that this approach become an effective approach in identifying land use changewhich is appropriate for many territorial and multi-temporal dimensions.
