摘要
随着地理信息系统(Geographic Information System,GIS)技术的迅速发展,其强大的空间分析技术愈来愈受到关注。在农业开发项目中,将GIS空间分析技术应用于农业开发项目选址中,可形象直观量化地展示项目选址结果。以清徐县马峪乡土地利用现状图、土壤图及气象图叠加形成评价葡萄园选址的图,选取对葡萄生长影响较大的9个因子,使用层次分析法确定权重,建立评价指标体系,通过累计分析计算得出选址结果;对研究区897个地块图斑进行评价,将研究区葡萄园选址划分为5个等级(最适宜区、高适宜区、中等适宜区、低适宜区、不适宜区),等级越高越适宜葡萄种植。将GIS空间技术与层次分析法有效结合,可以对葡萄园选址进行科学评价,并直观展示选址结果,为葡萄项目建设提供科学依据,大大提高选址的效率。
As the Geographic Information System（GIS）technology has developed quickly, people pay more attention to the spatial analysis. Applying GIS spatial analysis technology to agricultural development project location, it is easy to provide a scientific estimate and display project location results intuitively. The evaluation index system of the vineyard location was established by choosing 9evaluation indexs from 3 respects of landform, soil and climate in Mayu town. The result was used to determine the weight of calculated by superposition analysis. The 897 plots in the study area were evaluated, and the vineyard location in the study area was divided into 5grades（the most suitable area, the high suitable zone, the middle suitable zone, the low suitable zone and the unsuitable zone）. It can be conducted rapidly and quantitatively by membership function supported by GIS. The result can show the location result intuitively and make the scientific decision and improve the efficiency of the locate greatly.
