ASSESSING THE POTENTIAL LAND FOR PLANTING Michelia tonkinensis BY USING THE FUZZY ANALYTIC HIERARCHY PROCESS (FAHP) IN KON PLONG DISTRICT, KON TUM PROVINCE

Abstract

Michelia tonkinensis is multi-purpose tree providing both wood and seeds and creating high economic value. In the past few years, in Kon Plong district, Kon Tum province, there have been models of mono planting Michelia tonkinensis and intercropping with industrial trees or agricultural crops (coffee, cassava). However, the development of these models is based on the practical experience of localities that have successfully developed this species, therefore the assessment of the suitable levels for proposing solutions to develop Michelia tonkinensis to contribute to forest quality improvement by models of multi-purpose forest tree plantation in the locality. By using GIS techniques and Fuzzy Analytical Hierarchy Process (FAHP) with 4 key ecological factors (climate, soil, topographic, and vegetation status) with 7 secondary ecological factors (rainfall, temperature, soil length, soil type, elevation, slope, and forest and land use) to evaluate the suitability levels of planting Michelia tonkinensis in various ecological sub-regions. Potential land areas for planting Michelia tonkinensis in Kon Plong district are classified into 4 levels: Very suitable, suitable, less suitable and unsuitable. The ​​land areas is very suitable for planting Michelia tonkinensis is very low, only apporximate 1.60%, while the land areas are at less suitable level accounts for the largest proportion (74.14%); the area at suitable and unsuitable levels is samilarly, 10.00% and 14.26% respectively.
