Abstract:

Shifting cultivation has profound impact on land use and land cover change in Southeast Asia. Exploring the spatial distribution and variation rules and its influencing factors plays an important role in scientifically understanding LUCC, farmers' livelihood transition and maintaining ecosystem services. This paper uses remote sensing techniques to extract the spatial distribution of shifting cultivation in the border area of Myanmar, Laos and Thailand in the four years of 1996, 2000, 2003 and 2010, and uses GeoDA spatial autocorrelation analysis method and GIS spatial analysis technique to analyse spatial variation pattern, spatial autocorrelation of area and fragmentation of slash and burn agriculture, then further explores the difference of spatial variation in different countries. Results show that: the acreage of shifting cultivation in the border area of Myanmar, Laos and Thailand has experienced a process from slight increase to slight decrease and lastly substantially increased from 1996 to 2011. Both of the patch area and fragmentation of shifting cultivation has significant spatial autocorrelation. Swidden cycle and socio-economic factors may be the main reasons for the differences of spatial variation of slash and burn agriculture in different countries.

Key words: shifting cultivation, spatial variation, spatial autocorrelation, Moran's I, the border region of Myanmar,Laos and Thailand
