摘　　要：为了探明立体生态农业下蔬菜种植区域的适宜性情况,以具有典型的立体农业特征的黔东南州为研究对象,采用GIS技术运用层次分析法,建立蔬菜适宜性评价模型,分别对喜温型蔬菜和喜凉型蔬菜进行适宜性评价。结果表明:喜温型蔬菜高度适宜等级占16.56%,适宜等级占31.81%,勉强适宜等级占47.58%;喜凉型蔬菜高度适宜等级占16.98%,适宜等级占35.04%,勉强适宜等级占43.92%。潜育型水稻土均不适宜种植喜温蔬菜和喜凉蔬菜。在评级结果的基础上对蔬菜进行规划布局,黔东南州东南部低海拔区是喜温型蔬菜的主要种植区,西北部高海拔地区是喜凉型蔬菜的主要种植区。For the sake of exploring the suitability agriculture, suitability of warm-season vegetables of vegetable planting under stereoscopic ecological and cool-season vegetables were evaluated in Qiandongnan Prefecture which was with typically stereo-agricultural characteristics, by constructing vegetable suitability model using analytic hierarchy process （AHP） based on GIS. The results showed that highly suitability, suitability, and barely suitability of warm-season vegetables accounted for 16. 56%, 31.81% and 47.58%, respectively, while that of cool-season vegetables were 16.98%, 35.04% and 43. 92%, respectively. All gleyed paddy soil were not suitable for both warm-season and cool-season vegetables. For the planting planning and arrangement of vegetables based on the results of soil fertility level classification, low altitude areas in southeast of the district could be the main planting areas for warm-season vegetables, oppositely, high altitude areas in northwest of the district could be the major planting areas for cool-season vegetables.
