“猪-沼-果”水土保持综合治理模式简析

 “猪—沼—果”工程是20世纪90年代以来江西省赣南等水土流失严重地区综合治理水土流失的一种新模式,对巩固和促进治理成果取得了积极有效的作用。通过介绍“猪—沼—果”综合治理模式的内涵及“猪—沼—果”产业循环生态链,对“猪—沼—果”综合治理模式在小流域治理中的作用和效益进行全面阐述。其作用主要表现在3个方面:1)缓解能源紧缺的矛盾,保护自然植被,巩固治理成果;2)提供有机肥料,改善水土流失地土壤养分条件,促进开发性治理;3)促进小流域经济的发展,加快脱贫致富的步伐。同时,取得了显著的水土保持效益、生态效益和经济效益。

Management model of "Pig-methane tank-fruit" in soil and water conservation

“Pig-methane tank-fruit” model is a kind of new model for controlling soil erosion since 90's in the soil erosion severity region of Jiangxi, and the erosion control in Jiangxi was strengthen by it. The content of industrial ecocycling and the benefits of the model in the small watershed was introduced in this paper. Its function are mainly expressed in three aspects: 1) The antinomy of tightly energy lack was alleviated and plant cover is protected. 2) Organic fertilizer is provided, and the soil nutrient condition was improved. 3) The development of the small watershed economy is promoted, and the step that casting off poverty to get rich is quicken. Furthermore, the marked benefits of soil and water conservation are obtained.
