摘　　要：【目的】探明盘州市刺梨主产区耕地质量与刺梨生态效应,为盘州刺梨产业的合理开发及利用提供参考。【方法】以盘州市刺梨主产区为研究区,基于多元统计分析和耕地土壤养分质量评价等方法,采集土壤和刺梨样品,测定其pH、有机质、土壤养分和重金属含量,并对研究区土壤耕地质量及刺梨生态效应进行评价分析。【结果】与中国A层土壤背景值比,除K、Ti含量偏低外,其余元素含量均超过背景值;土壤整体偏酸性,酸性土壤面积为4700 hm^(2),占种植园区耕地面积的83.21%;耕地养分以较丰富级耕地为主,占园区耕地面积的74.85%,在PG镇均有分布;耕地土壤环境以安全利用类为主,占园区耕地面积的80.56%,主要分布在PG镇中部至东部。仅1个刺梨样品富Se,刺梨对土壤中Se的富集作用较强,Hg和Cd次之,存在一定的潜在风险。【结论】PG镇耕地养分、环境质量及生态环境情况较好,可根据实际规模化种植刺梨。【Objective】The cultivated land quality of main growing area of Rosa roxburghii in Panzhou City and ecological effect of R.roxburghii are studied to provide a reference for the rational development and utilization of R.roxburghii industry in Panzhou.【Method】Taking main R.roxburghii growing area in Panzhou City as the research area,based on the methods of multivariate statistical analysis and soil nutrient quality evaluation on cultivated land,soil and R.roxburghii samples are collected to determine the pH,organic matters,soil nutrient and heavy metal content,and then the cultivated land quality and ecological effect of R.roxburghii in the research area are evaluated and analyzed.【Result】Compared with the background value of layer A soil in China,K and Ti content are slightly low,and other elements content all exceed the background value.The soil is acidic,with an area of 4700 hm^(2),accounting for 83.21%of the cultivated land area in the plantation area.The nutrient of cultivated land is relatively abundant mainly,accounting for 74.85%of cultivated land area in the plantation area,which is distributed in PG Town.The soil environment of cultivated land is mainly for safe use,accounting for 80.56%of cultivated land area,mainly located at middle to east PG Town.There is only one R.roxburghii sample enriched in Se.R.roxburghii has strong enrichment effect to Se in soil,followed by Hg and Cd,indicating there is a certain potential risk.【Conclusion】PG Town has the better cultivated land nutrient,environmental quality and ecological environment,and R.roxburghii can be planted large-scale according to the actual conditions.
