摘　　要：为优化作物种植的总体布局,使区域经济结构和生态环境实现可持续发展。以橙子为研究对象,通过提取适宜性评价自然和社会因子、用模糊方法对数据定量化处理、用层次分析法对评价结果进行排序定权叠加分析,最终使用有序加权平均算法进行风险评价,得到橙子种植用地适宜性综合评价结果。研究表明:(1)选取的12项适宜性指标得当,各因子影响程度的权重确定合理,评价结果贴合实际情况;(2)从适宜面积看,江西省大部分土地适合橙子种植,其中非常适宜占34.8%,比较适宜占34.4%,而仅有22.7%的土地一般适宜、8.1%的土地不适宜;(3)从分布来看,江西省中部种植适宜性高,北部庐山地区和修水县周边不适宜,全省的周边区域和山地丘陵地带适宜性偏低。In order to optimize the overall layout of crop planting,achieve sustainable development of the regional economic structure and ecological environment,this study takes orange as the research object.By extracting suitability evaluation of natural and social factors,using fuzzy method to quantitative data processing,using analytic hierarchy process to evaluate the results sorted weights-making overlay analysis,finally assessing risk using ordered weighted average algorithm,orange planting land suitability evaluation results are obtained.The research shows that(1)the 12 suitability indexes were selected properly,the weight of influence degree of each factor was determined reasonably,and the evaluation results were in line with the actual situation.(2)In terms of suitable area,most of the land in Jiangxi province is suitable for orange planting,among which 34.8%is very suitable,34.4%is relatively suitable,and only 22.7%of the land is generally suitable and 8.1%is not suitable.(3)From the perspective of distribution,the suitability of planting in central Jiangxi province is high,the suitability of planting in northern Lushan area and Xiushui county is unsuitable,and the suitability of planting in surrounding areas and mountainous and hilly areas of the whole province is relatively low.
