摘  要：
对玉米(Zea mays)田养鹅和传统玉米种植(CK)下的田间杂草进行调查,统计分析各杂草群落中杂草的密度、生物多样性指数以及群落的相似度系数,并对比2种处理的经济效益。结果表明:玉米田养鹅处理的物种丰富度指数、优势度指数和多样性指数分别比对照处理高11.4,0.07和0.2,而Pielou均匀度指数比对照处理低0.01,不同处理下杂草群落的相似性系数为0.77;玉米田养鹅处理每hm~2的净收入为13984元,比对照增加7063元。玉米田养鹅处理方式不仅维持了较高的生物多样性,并且经济收益更高。

摘  要：
Raising geese in cornfields(hereinafter referred to as RGICF) is a compound treatment based on the principle of "Agro-pastoral Integration",which was proposed in 2011.Its core content is the compound production model of resource utilization.The traditional planting pattern of corn was taken as control(CK) in this study.The density and biodiversity of weeds,as well as the coefficient of community similarity were analyzed in different weed communities.The economic benefits of different treatments were compared.Result showed that the species abundance index,dominance index and biodiversity index of RGICF treatment were higher than that of CK treatment,whereas the evenness index was lower than that of CK treatment.The coefficient of weed community similarity among different treatments was 0.77.In the aspect of economic benefit,the net income of RGICF treatment was 13984 yuan · hm~(-2),that 7063yuan · hm~(-2) higher than that of CK treatment.Overall,the RGICF treatment not only kept the higher biodiversity,but also got the outstanding economic benefit.
