摘要
以沈阳市西郊镉污染农田种植的18种草坪草作为研究的样本单元,以每个品种观测到的4个性状特征作为目标值(V1为株高,V2为病害(钱斑病),V3为分蘖株,V4为全草含镉量),对它们进行多目标决策的分析,从而为农业生态工程中优选抗镉能力强和富集能力强的草坪草品种提供了数量化依据。分析结果表明:普特、优异、结缕草草地早熟禾等草种对镉富集能力较强,是改造镉污染地的优良草种。
Multi-objective strategy was performed by analyzing 18 lawn species contaminated by cadmium in the western suburb of Shenyang City and its target value from 4 characters （mean height V1, disease V2, tiller V3 and total grass cadmium content V4）, which provided basic data for optimizing lawn species which were highly cadmium-tolerant and-concentrated in ecological engineering in agriculture. The result showed Putter, Merit, and Kentucky bluegrass, ere were optimal species for concentrating cadmium and reconstructing contaminated area.
