콩과 옥수수 재배적지 평가에서 GIS 와 AHP 방법의 적용 -베트남의 Tien Giang도-

The purpose of this research is to build a model using Geographic Information System (GIS) and Analytical Hierarchy Process (AHP), to illustrate which areas are suitable for Maize and soybean production in Tien Giang Province, Vietnam. Based on the suitable conditions for growing of soybean and maize, experts’ opinions, previous researches and the available data resources, the criteria to be used for land suitability analysis are soil type, soil depth, mean temperature, relative humidity, precipitation, slope and distance to water source. On the basis of these criteria and using GIS technique single-criterion maps were generated and then the standardization will be conducted to these single-criterion maps through fuzzy membership function. Land suitability analyses were performed by using analytical hierarchical process (AHP) to give a specific weight for each criterion, which represents its relative importance in the suitability evaluation. The weighted linear combination (WLC) will be used to combine the standardized factors and their corresponding weights to obtain an overall suitability map for the cropland. The result of this study is expected to show the suitability ratios of highly, moderately, marginally and not suitable area for maize and soybean. The model is expected to improve the planning, and also assist in accurately recognizing the additional sites for soybean and maize planting in the future.
