摘　　要：以江西省定南县龙塘镇杏林农庄"猪-沼-果-鱼"生态农业模式为例,系统研究了该模式的关键技术与农业面源污染控制效果。杏林农庄内实施山顶种植水土涵养林,山腰开梯田种脐橙,园间栽培生草,山脚保留防护植被带,山脚建造养猪场和沼气池,沼气池下游建有多级鱼塘,已形成较典型的"养猪-沼气-果树-养鱼"四位一体的物质循环和能量梯级利用的综合生态农业模式。分析认为该模式的推广应用有助于有效控制农业面源污染,防止东江源头区水质恶化,具有良好的经济、社会和生态效益。A case study was performed of the ＂pig-biogas-fruit-fish＂ eco-agriculture model in Xinglin Farm,which is located in Longtang Township,Dingnan County,Jiangxi Province,for systematic study on key techniques and agricultural non-point pollution control effect of the model.The farm planted trees on top of the hills for soil and water conservation,and navel orange trees in terrace fields with grasses growing like a cover on the hillside,kept protective vegetation belts at the foot of the hills,set up pigsties and biogas digestors in the valley and built up multi-leveled fish ponds in the downward,thus forming an integrated ＂pig-biogas-fruit-fish＂ eco-agricultural system that features closed material cycle,cascade use of energy and ecological protection.The extension of this model may effectively help the control of agricultural non-point pollution,prevent water quality degradation of the headwaters of Dongjiang River and yield remarkable ecological,economic and social benefits as well.
