为综合分析已有研究结果，探究不同稻田综合种养模式的经济效益，基于中国知网、万方、Web of science等数据库，以稻田综合种养模式、经济效益等关键词检索筛选获得81篇文献，并运用荟萃分析法，对稻田综合种养模式经济效益及其影响因素进行统计分析。结果表明:1)与水稻单作模式相比，稻田综合种养模式的经济效益显著提升，在不同稻田综合种养模式类型中，稻鸭模式和稻鱼模式的经济效益较高;2)在不同时间阶段和地理区域，稻田综合种养模式的经济效益有所差异;3)自然环境因素和社会经济因素会对稻田综合种养模式经济效益产生显著影响，试验特征的不同也会影响稻田综合种养模式经济效益的研究结果。基于此，本研究提出针对性的政策建议，旨在为政策制定者和农业推广者等相关主体提供有益借鉴，以期促进我国稻田综合种养模式的广泛应用。
Economic benefits and influencing factors of the comprehensive rice farming and breeding model in China:Evidence based on meta-analysis
In order to comprehensively analyze the existing research results and explore the economic benefits of different rice field comprehensive planting and breeding models,based on the databases of China Knowledge Network,Wanfang and Web of science,81 documents were obtained by searching and screening with keywords of integrated rice-farming model and economic benefits,and meta-analysis was applied to statistically analyse the economic benefits of the integrated rice-farming model and its influencing factors.The research results indicate that:1)Compared with the rice monoculture model,the economic benefits of the rice field comprehensive planting and breeding model are significantly improved.Among different types of rice field comprehensive planting and breeding models,the rice duck model and the rice fish model have higher economic benefits.2)The economic benefits of the integrated rice farming model vary at different time stages and geographical regions.3)Natural environmental and socio-economic factors will have a significant impact on the economic benefits of the integrated rice farming model,and the different experimental characteristics will also affect the research results of the economic benefits of the integrated rice farming model.Based on this,this study proposes the targeted policy recommendations to provide useful references for policy makers and agricultural promoters and promote the widespread application of comprehensive rice cultivation models in China.
