| ［目的］柠檬是典型的云南高原特色水果，作物生态适宜性区划是综合环境生态因子和空间分析工具的种植区划方法。［方法］研究采用德尔菲法从气候、土壤理化、地形地貌因子3个方面确定了10个生态适宜性评价指标，使用层次分析法进行各生态适宜性因子权重系数的确定，结合ArcGIS进行云南省柠檬种植生态适宜性精细化区划研究。［结果］德宏、普洱、西双版纳、临沧西部、红河南部及文山东部是种植适宜区，占全省面积的378%； 保山、楚雄、大理南部、丽江东部、玉溪南部、红河北部、曲靖南部是种植次适宜区，占全省面积的337%； 迪庆、怒江、丽江西部、昆明、昭通及曲靖是种植不适宜区，占全省面积的285%。［结论］研究方法可以推广应用到其他高原特色水果的生态适宜区种植区划，对指导作物科学选址具有重要意义，对合理规划生态布局、科学种植及尝试定向培育具有重要的指导意义。 |

| Abstract: |
| Lemon is a typical fruit of Yunnan plateau. Crop ecological suitability zoning is the spatial classification of plant growth adaptability with systematic environmental and ecological factors. In this study, we firstly applied Delphi method to select 10 ecological suitability assessment indexes from three scopes of climatology, edaphology and topography. Then we calculated the weight coefficients of each factors with the Analytic Hierarchy Process (AHP), and plotted the map of Yunnan province ecological suitability assessment for lemon plantation using ArcGIS. The results showed that, Dehong, Pu′er, Xishuangbanna, West of Lincang, South of Honghe and East of Wenshan were the most suitable areas for lemon plantation, accounting for 37.8% of the Yunnan province. Baoshan, Chuxiong, Southern Dali, Eastern Lijiang, Southern Yuxi, Northern Honghe and Southern Qujing were inferior areas of suitability for lemon planation, accounting for 33.7% of the province′s area. Diqing, Nujiang, Western Lijiang, Kunming, Zhaotong and Qujing were unsuitable areas for lemon planation, accounting for 28.5% of the province′s total area. The methods as well as the indexes system for lemon plantation suitability assessment are adaptable to other plateau areas that are preparing for fruit planation. These results revealed by this study are of great significance for distribution of the crop/fruit plantation, for planning of the environmental and ecological development, and for guiding the plantation and directive breeding. |
