There are many researches concerning the deforestation but in fact are not comprehensive enough to understand the interactions between the its causes in particular socio-economic and historical conditions of the country, especially in the mountainous areas. This study attempts, therefore, to use the cartographic approach to focus on the interaction between the deforestation and the needs of subsistence of local people, namely the food production, in the Na Hang district, Tuyen Quang province of the region of Northern Uplands of Vietnam. The spatial scale of analysis is the national, regional and communal. The temporal scale is about 100 years for Vietnam, about 40 years for the district and the commune. The multiscaling analysis in this research is useful to understand deeply the effect of socio-economic forces on the complex process as the deforestation. This approach is proved to be effective to clarify the spatial distribution of the forest, agricultural land and food production in space and time. Furthermore, all statistical data such as demographic data, ethnic groups, agricultural lands, sown areas of food cultures, other socio-economic data and forest statistics have been represented on the basis of administrative limits of commune in order to find out the relations between these phenomena. By this way, the whole picture of study area has been reconstructed in its historical evolution in the integration with the principle policies related to the land use and development issues.
