Research On Comprehensive Benefit Evaluation Of Rice And Fishery Breeding Mode In Tianjin

In recent years,with the modernization of agriculture,the transformation and upgrading of agriculture is related to the sustainable agricultural development.While seeking sufficient food supply,people should continue to explore green and ecological agricultural development methods,which are crucial to national economic growth and stable social development.Rice and fishery integrated farming is a typical ecological cycle agriculture,which can ensure food security and aquatic product supply,promote agricultural efficiency,increase farmers’ income,and promote high-quality agricultural development.As a typical area of rice and fishery cultivation,Tianjin plays an important role in stabilizing grain and promoting fishery.Through the rational combination of rice production and aquatic product breeding,the goal of "one water for dual use,one field for two harvests" is achieved,and the benefits of agricultural development are stimulated to the greatest extent.In order to promote the high-quality development of rice and fishery breeding in Tianjin,on the basis of field research,the comprehensive benefits of rice and fishery breeding mode in Tianjin were thoroughly studied,and the comprehensive benefit evaluation index system of rice and fishery breeding in Tianjin was constructed,and its benefits were scientifically and objectively evaluated,which could provide a theoretical basis for the high-quality development of rice and fishery in Tianjin.By comparing the benefits of rice and fishery breeding mode with conventional rice breeding mode,the comprehensive benefit level of rice fishery breeding mode can be more intuitively obtained,so as to further improve the comprehensive benefit of rice and fishery breeding and promote the high-quality development of rice and fishery in Tianjin.The following is the specific research content of the paper:(1)The comprehensive benefit evaluation index system of rice and fishery breeding was constructed,on the basis of field research,Combining the characteristics of rice and fishery farming,the first-level indicators with economic,ecological and social benefits as the core were established,and 18 second-level detailed indicators such as total output value per hectare,material consumption output value rate,and net profit per hectare were established,so as to form a comprehensive benefit evaluation index system for rice and fishery breeding.(2)Empirical analysis of the comprehensive benefit level of rice and fishery breeding in Tianjin.Indicator weights for rice-fishery farming and conventional rice models were calculated using the analytical hierarchy and the entropy value methods,and according to the weight results,using the fuzzy comprehensive analysis and evaluation method to evaluate,and the rice fishery breeding mode’s economic benefit level was the highest showed by the results,the ecological benefit was second,and the social benefit needed to be improved.The comprehensive benefits of rice and fishery farming mode were higher than those of conventional rice model,and the evaluation score was 79.578.Among them,the economic benefits of the two agricultural models were as follows: rice fishery farming mode > conventional rice model;The order of ecological benefits was as follows: rice fishery culture mode > conventional rice model;The social benefits were sorted as follows: rice fishery farming model < conventional rice model.(3)Based on the results of the empirical analysis,given the problems of the rice-fishery farming model in terms of integrated benefits.,the paper proposes to change the traditional planting and breeding concept under the guidance of the "two mountains" theory;Promote the appropriate scale of planting and breeding,and consolidate the foundation for the improvement of ecological benefits;Strengthen brand awareness and expand the growth space of economic benefits;Suggestions on strengthening technology promotion and social services,and improving the mechanism of social benefits.
