摘要紫色土是世界上一種特殊的土類，集中分佈於四川盆地，以其易成土性和富鹽基性（自然肥力高）養育著500人以上平方公里的人口而著稱於世，但是它分佈的區域存在嚴重的季節性乾旱和時有發生的洪災等水問題。 -
Under the direction of chinese soil taxonomy, part purple soils developed on the purplish standstones of j2 # j3 in sichuan basin were systematically studiedaccording to natural landscape, profile modality and quick - test, applying to methods statistic analysis and system integration, main affecting factors, indexs of soil series taxonomy and retrieval orders were systematically discussed. the results showed : 1 ) organic substance, total nityogen, total phosphate, total potassium and particle size composition were distinctly related with many soil characters. organic substance, calcium carbonate, available phosphate # size composition were much different in all swatches. besides, soil structure and the depth had profound affection to it. 2 ) affecting factors : soil structure, texture style and organic substance phosphorous
本文以土壤系統分類理論為指導，以四川盆地侏羅系蓬萊鎮組、沙溪廟組和遂寧組紫色巖上發育形成的部分紫色土為研究對象，利用spss統計軟體相關功能，結合供試土壤的自然景觀、剖面形態和室內測定的理化性質，對土系分化的影響因子、土系劃分指標和檢索順序進行了系統的探討，結論如下： （ 1 ） 、供試紫色土中有機質、全氮、全磷、全鉀和顆粒組成與多個土壤性質均呈顯著或極顯著相關；有機質、碳酸鈣、有效磷、顆粒組成等性質在供試土壤方差分析中變異系數均較大；土體構型及土體的深度對土壤性質也有深刻影響。 -
