重庆三峡库区特色农业循环经济研究--以"猪 沼 橘"生态农业模式为例

针对重庆市三峡库区农业发展实际,从促进农村经济发展、保护生态环境、减少农业污染等方面分析了发展农业循环经济的必要性,并从资源、技术和政策等方面分析了三峡库区发展农业循环经济的有利条件。详细介绍了在三峡库区柑橘、生猪、沼气产业基础上建立的循环农业成功模式——"猪–沼–橘"生态农业模式。该模式2008~2009年累计在三峡库区的江津、长寿、开县等十余个沿江柑橘重点区县共计推广6700hm2,合计增收节支1.2亿元,解决了2万余劳动力就业,改善三峡水库水质、保护库区生态环境等效果明显。最后,提出了促进三峡库区循环农业发展的措施。

Characteristics of agricultural circular economy in the Three Gorges Reservoir Region of Chongqing- A case study of the ecological agriculture pattern of "pig-biogas-orange"

Based on agriculture development in the region, this study analyzes the conditions and necessity for agricultural circular economy in the Three Gorges Reservoir Region of Chongqing from the rural economic development, environment protection and agricultural pollution control. And the advantages of resources, technology and policy for the agricultural circular economy in the region was discussed. The successful "pig-biogas-orange" pattern of agricultural circular economy established on the industrial bases of orange cultivation, pig breeding, and biogas production in the Three Gorges Reservoir Region is fully elucidated. The pattern is practiced in more than 10 counties in a total area of 6 700 hectares of main citrus plantation in the counties of Jiangjin, Changshou, Kai, etc. It has an average income increase of 120 million Yuan and over 20 000 employments in the region. The agricultural circular economy pattern obviously also enhances the water quality of Three Gorges Reservoir and protects the environment of the region. Further strategies for promoting agricultural circular economy in the Three Gorges Reservoir Region are therefore recommended.
