摘　　要：为探明我国中部沿江山区生态涵养型土地整治技术,采用样方法对安徽省池州市贵池区涓桥镇普丰新村农田生态系统进行杂草种类及其群落特征的调查研究。结果表明:1)不同种植方式农田内杂草的群落结构不同,大豆样田内共有5科、9属、9种杂草,蔬菜样田内共有4科、8属、8种杂草,棉花样田内共有7科、8属、8种杂草,水稻样田内共有4科、4属、5种杂草;2)物种丰富度也因为不同种植方式而明显不同,其中,大豆田9种杂草、菜地8种杂草、棉花田8种杂草、水稻田5种杂草;3)示范区内农田杂草以禾本科、苋科和莎草科为主,其中,大豆田内禾本科和苋科杂草占田内杂草总数的80%以上。结论:不同农田种植方式杂草群落结构组成相差很大,种植方式决定了杂草群落的多样性特征。To ascertain the technology of land comprehensive reclamation based on ecological conservation in midland moutain area along the Yangtze river in China,by using quadrate sampling method the authors conducted the field surveys of species diversity of weed community in different farmland located in Pufeng Village.Results：1 ）The weeds community structure varied in different planting modes of farmlands.There were nine weed species belonging to nine genera and five families in soybean sample field;4 families,eight weed species belonging to eight genera and four families in vegetable sample field, eight weed species belonging to eight genera and seven families in cotton sample field and five weed species belonging to four genera and four families in paddy sample field. 2 ） The species richness of weed community varied with different planting mode.There were nine weed species in soybean field,eight weed species in vegetable field,eight weed species in cotton field and five weed species in paddy field.3 ）The compositions of weed community in farmland were dominated by Gramineae, Amaranthaceae and Cyperaceae.The amount of Gramineae weeds and Amaranthaceae weeds accounted for more than 80% of quantity of all weeds in soybean field.Conclusion：Weeds community structure in different planting method were greatly discrepant,and the diversities of weed community were determined by planting method.
