摘　　要：为了从研究什么样的环境条件下更适合种植云南重楼和环境因子中与云南重楼平均净增产量关联密切的因子,利用灰色系统理论,将环境因子和平均净增产量组成一个灰色系统,对同一组数据从不同试验点与理想指标的灰色关联分析和平均净增产量与各项环境因子的灰色关联分析两个层面加以研究,结果表明,试验点的灰色关联度排序是:丽江玉龙县石头乡利苴(H5)>大理鹤庆县马场(H7)>丽江玉龙县鲁甸乡拉美荣(H6)>丽江玉龙县石鼓镇(H1)>丽江玉龙县巨甸镇德良(H3)>丽江古城区白沙乡高山所试验基地(H4)>丽江玉龙县巨甸镇金河(H2);环境因子的灰色关联度排序是:有效氮>有机质>全氮>全磷>有效磷>有效钾>降雨量>海拔>p H值>全钾>最热月平均气温>年均气温>年≥10℃积温>最冷月平平均气温。综合分析结果,表明H5、H7和H6试验点的土壤中有效氮、有机质、全氮、全磷都比较协调,易获得高产。针对应用与推广,测土结合配方施肥很关键,对土质粘性和砂性的地块,采取客土措施以改善土壤的微环境有利于云南重楼的生长。In order to understand what environmental conditions is suitable for planting the Paris polyphylla var. yunnanensis（ Fr.） and What is the connection between environmental factors and the growth of Paris polyphylla var. yunnanensis（ Fr.）,based on the grey system theory,the environmental factor and mean net yield was constructed as a grey system in this study. Based on the same data set,grey correlation analysis was used in two aspects what were different testing point and the ideal index,and environmental factors and mean net yield. The results showed that,The grey correlation degree of different test points is the sort of： Yulong stone township in Lijiang liju murai（ H5） Heqing machang township in dali（ H7） Yulong ludian township in Lijiang lameirong murai（ H6） Yulong shigu township in Lijiang（ H1） Yulong judian township in Lijiang deliang murai（ H3） The Lijiang old city area baisha township（ H4） Yulong judian township in Lijiang jinhe murai（ H2）; The grey correlation degree of different environmental factors is the sort of： Available N Organic matter Total N Total P Available P Available K Rainfall Altitude p H value Total K Mean temperature of the hottest month Annual mean temperature 10℃ Accumulated temperature Mean temperature of the coldest month. Comprehensive analysis of two results showed that the soil available nitrogen,organic matter,total nitrogen,total phosphorus of the test points of H5,H7 and H6 were more coordinated. Aimed to the application and promotion,formula fertilization by soil testing is one of the key measures. And at the clay soil or sand soil land,using alien earth can improve the soil micro-environment to promote the growth of Paris polyphylla var. yunnanensis（ Fr.）.
