摘　　要：为探究适宜山东省东营市玉米种植的高效间作模式,设置玉米-辣椒(4行∶5行)、玉米-大豆(4行∶6行)、玉米-花生(4行∶6行)和玉米-天人菊(4行∶6行)4种间作模式,以单作玉米作为对照组,基于农田生态系统服务功能价值理论,通过初级产品经济价值和人工及生产资料等投入成本来估算各间作模式的经济效益,并结合生态系统的控害能力、物种丰富度和土壤营养指标来综合评估各间作模式的生态服务价值。结果表明,相较于单作玉米模式,玉米-大豆和玉米-花生间作模式的经济效益分别增加了48.44%和13.02%;玉米-辣椒和玉米-大豆间作模式的虫害发生量显著减少了50.00%和68.75%,同时物种丰富度分别提高了32.21%和33.13%;玉米-大豆和玉米-花生间作模式的土壤有机质积累量分别显著提高了150.04%和131.49%。综合评估结果表明玉米-大豆间作的经济价值和土壤调节能力最优,玉米-天人菊间作的物种丰富度最高,其生态涵养能力最佳,可针对东营市玉米产业的不同需求选择适宜的间作模式。In order to explore the efficient intercropping mode suitable for maize planting in Dongying City,four intercropping modes,namely,maize-pepper mode(4∶5),maize-soybean mode(4∶6),maizepeanut mode(4∶6),maize-chrysanthemum mode(4∶6),were set in this study based on the theory of farmland ecosystem service value compared with the control group of maize monoculture mode.The economic benefits of each intercropping mode were estimated by the economic value of primary products,the input costs of labor and means of production.The ecological service value of each intercropping mode was evaluated comprehensively by combining the damage control ability,species richness and soil nutrition indexes of the ecosystem.The results showed that,compared with control group,the economic benefits of maize-soybean and maize-peanut intercropping modes increased by 48.44%and 13.02%,respectively.In maize-pepper and maize-soybean intercropping modes,the number of pests significantly decreased by 50.00%and 68.75%,while the species richness increased by 32.21%and 33.13%,respectively.Moreover,the accumulation of soil organic matters in the maize-soybean mode and the maize-peanut mode was significantly increased by 150.04%and 131.49%compared with the control group.As a consequence,the economic value and soil regulation ability of maize-soybean mode were the optimal.The species richness of maize-chrysanthemum mode was the highest,and the ecological conservation ability was the optimal.The suitable intercropping mode could be selected according to different demands in maize production in Dongying City.
