摘要
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。
Abstract
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.

由于本研究分析的数据来自各类文献,且不同文献在衡量稻田综合种养模式经济效益时通常受到实验年限、测度方法及当地经济发展条件等因素的影响,导致种养模式经济效益的评估标准可能有所差别。根据文进等[8]的观点,在对同一干预措施采用不同测量方法或单位时,例如使用不同量表进行测量,或者不同研究之间均数差异较大时,宜选择标准化均数差(Standardized mean difference,SMD) 作为合并统计量。具体来说,标准化均数差是两组估计均数差值与合并标准差的比值,用来衡量两组数据之间的差异,度量单位或测量方法不一致的情况。由于消除了量纲的影响,因此结果能够被有效合并。因此,本研究采用同一实验中稻田综合种养模式与水稻单作模式净利润的标准化均数差(SMD)作为效应值,衡量稻田综合种养模式的经济效益。
