三峡库区小城镇庭院生态模式及效益分析——以江津区油溪镇为例

Eco-model and Benefit Analysis of Courtyard in Small Town of Three Gorges Reservoir Areas

以江津区油溪镇为例,在实地调查的基础上,充分考虑其自然环境条件、畜牧业发展现状,依据生态学物质循环利用的原理,提出了以沼气池为纽带、多级利用畜禽粪便、多途径提高秸秆生物质能利用率的庭院生态模式。在此基础上分析了发展此模式带来的环境效益、生态效益、社会效益及经济效益,并得出应在三峡库区大力推广此模式的结论。

Based on field investigation of Youxi town which gives a full consideration of its natural environment and current situation of livestock development,an ecomodel of courtyard has been proposed with the ecological principle.The pattern with biogas digester as a link can not only treat domestic waste multi-levelly,but also promote the bio-energy＇s efficiency of straw.Then,this paper analyzes environmental benefits,ecological benefits,social benefits and economic benefits of the eco-model.Thus,this eco-model of courtyard should be widespread in Three Gorges Reservoir areas.
