摘要

通过实地调查、土壤采样分析和数理统计结合的方法，对川中丘陵区5种土地利用方式（水田、旱地、菜地、林地和荒草地）的土壤养分状况进行对比分析，结果表明．土地利用方式对土壤有机质、全氮、全钾、全磷、碱解氮、速效钾和速效磷含量的影响达极显著（或显著）水平；在5种土地利用方式中．土壤有机质和全氮含量由高到低的顺序为：水田〉林地〉菜地〉旱地〉荒草地；土壤全钾和速效钾含量由高到低的顺序为：水田〉菜地〉旱地〉林地〉荒草地；土壤全磷含量由高到低的顺序为：菜地〉旱地〉林地〉水田〉荒草地。

Abstract

By the method of soil sampling and laboratory analysis

effects of different land use types on soil nutrients have been discussed. The result indicated

the different land use types have significant impacts on soil nutrient. The content of soil organic matter and total N decline in sequence from paddy land

forest land

vegetable land

dry land to grassland. The content of soil total K and available K decline in sequence from paddy land

vegetable land

dry land

forest land to grassland. The content of soil total P decline in sequence from vegetable land

dry land

forest land

paddy land to grassland.
