| 摘 要： | 采用投影寻踪法对西藏波密波棱瓜野生地与栽培地土壤肥力质量进行了对比研究。野生地与栽培地的土壤肥力质量函数投影值排序。结果表明,野生地土壤的肥力质量综合评价值为1.7609,栽培地仅为0.2682,野生地土壤的肥力质量极显著高于栽培地(n=6,P<0.01),野生地土壤肥力质量远高于栽培地。为后续栽培地土壤培肥、模仿野生地土壤肥力措施的正确运用,提供理论评价依据和技术决策参考。

| Abstract: | APC(Projection Pursuit Classification) model based on RAGA(Real coding based Accelerating Genetic Algorithm) was applied for the comparison of soil fertility quality with wild and cultivated land of Herpetospermum pedunculosum in Tibet.The results showed that the wild land quality assessment of soil fertility was 1.7609,while the cultivated land was only 0.2682,wild land quality and soil fertility were significantly higher than that of cultivated land(n= 6,P<0.01),which showed that the wild quality of the soil’s fertility was much higher than that of the cultivated land.The method for the correct application of improvement of soil fertility in the cultivated land and imitation of soil fertility measures in the wild land in the future,and provides a theoretical evaluation basis and technical reference. |
