摘要

本研究的主要目的是利用AHP - GIS和遥感技术确定最适合水稻种植的土地。清化省巴托区被选为进行实验设置的目标地区。根据科学家的意见和世界粮食组织(FAO)对农作物的指导，评估作物生态适应性的选择标准包括土壤类型、土壤质地、土壤深度、土壤pH值、N(%)、海拔、坡度、与河流的距离、年降水量、低平均和高温、平均日照时数、盐水入侵。考虑标准权重，将各分量图叠加生成土地适宜性图。结果表明:试验区近8.26%的土地利用面积非常适宜种植水稻，26.29%为中等适宜，43.35%为不适宜，22.1%为不适宜种植水稻。总的来说，这些数据可能对国家政府、决策者、管理人员以及地方当局有价值，以诱使当地农民在最合适的地区生产水稻

Application of MCE-AHP technical for modelling paddy zoning: A case study in Vietnam

The main aim of present study was to determine the most suitable land for paddy via AHP - GIS and Remote Sensing. Ba Thuoc district - Thanh Hoa province was selected as the target area to conduct the experimental set-up. As per opinion of scientists and the guidance of World Food Organization (FAO) on agricultural crops, the criteria selected to estimate the ecological adaptation of crops include soil type, soil texture, soil depth, soil pH, N (%), elevation, slope, distance from rivers, yearly precipitation, low-average and high temperature, average sunny hours, saltwater intrusion. The land suitability map was generated by superimposing the component maps considering the weighting of the criteria. The obtained results showed that in the experimental area nearly 8.26% of the land-use region was very appropriate for rice growing, 26.29% was observed medium appropriate, 43.35% was less appropriate and 22.1% was not fit for paddy cultivation. Overall, the data may be of value for country government, policy makers, managers as well as local authorities to induce local farmers for paddy production on most suitable areas

期刊介绍： The fundamental task set by the editors of the journal is to bring together and present a diversity of research connected with ecology. Apart from the traditional ecological research areas, the scope of the journal will embrace more peripheral ecological issues connected with other disciplines of biology. Recognizing the increasing importance of the humanities in ecological research, the editors will strive to give such issues due representation in the journal. We hope to encourage the researchers contributing to the journal to adopt an unconventional approach to solving ecological problems, to go beyond classical, well-established conceptions, and to include methodological and anthropological issues. Such an approach is validated by the intensive development of the sciences bordering on both biology and the humanities that has been observed over recent years.
