摘要：

为了说明四川省郫都区轮作模式的可持续性,及其潜在的经济及环保价值。基于投入产出理论,对郫都区5种典型轮作种植模式构建价值投入产出表与投入产出系数表。通过传统轮作模式与现代连作模式的比较,以及传统模式之间的比较,直观地对郫都区现有的轮作模式进行可持续性分析和评价。结果表明,由于传统的轮作模式符合作物自然生长规律,对农药和化肥的依赖性远低于现代连作模式,并较好地保持了农作物的生物多样性,但其单位面积产出低于连作模式。对稻蒜、稻韭、稻菜、稻姜和稻萝5种传统的轮作模式进行投入产出分析发现,5种模式单个产品投入和产出占比几乎一致,说明郫都区这种水旱轮作模式是一个有机整体,统一而又协调。要使传统的轮作模式得以发扬与传承,郫都区应打好天府水源地有机绿色农产品品牌,政府在相关政策方面应予以相应的鼓励和支持。

Abstract:

To explain the sustainability of the rotation mode in Pixian, Sichuan and its potential economic and environmental value, based on the theory of input-output, we built the value input-output table and the input-output coefficient table of 5 typical traditional rotation modes. Through the comparison between the traditional rotation mode and the modern continuous cropping mode, and the comparison between the traditional modes, we intuitively analyzed and evaluated the sustainability of the current rotation mode in Pixian. The results showed that: the dependency of the traditional rotation on pesticides and fertilizers was much lower than that of modern continuous cropping modes, and the biodiversity of crops was kept better because the traditional rotation mode conformed to the natural growth law of crops, but the output per unit area was lower than that of the continuous cropping mode. Input-output analysis of 5 traditional rotation modes of rice-garlic, rice-leek, rice-greens, rice-radish and rice-ginger found that: the input and output of the individual products were almost the same in 5 modes, indicating that this flood and drought rotation mode was an organic whole, unified and coordinated. In order to promote and inherit the traditional rotation mode, Pixian should build a good brand of organic green agricultural products in unique water source, the government should give corresponding encouragement and support in relevant policies.

Key words: agricultural cultural heritage, traditional flood and drought rotation mode, modern continuous cropping mode, input-output model, sustainability
