摘要
对笋用小径竹林土壤有机农药残留量主成分的分析表明,前3种主成分的贡献率分别为43.927%,26.429%和11.720%,土壤有机农药污染主要为有机氯和拟除虫菊类农药.经主成分综合因子分析,笋用小径竹林土壤有机农药污染可分为三类,即集约经营竹林>中等集约经营竹林>粗放经营竹林.
Concentrations of organ-pesticide in the bamboo forest of Zhejiang provance were determined and the principal component analysis was used simultaneously to evaluate the extent contamination of shooting bamboo forest contamination.Results showed that the first three components accounted for 43.927%,26.429% and 11.720% of the total variance respectively,which exhibited that organochlorine pesticide and pyrethroid were the main sources of organ-pesticide contamination.Comprehensive factor analysis were applied estimate the extent contamination further.Results show that organ-pesticide contamination of bamboo forest could be divided into three groups：intensive management bamboo forest〉moderate intensive management bamboo forest〉extensive management bamboo forest.
