摘要
果化示范区的立体生态农业由粮食作物（玉米）-经济作物（黄豆）-牧草轮作模式、果树（火龙果、澳洲坚果）-药材（金银花、苦丁茶）模式及水源林-牧草-畜禽模式等组成,充分利用了岩溶峰丛洼地自然环境提供的光、热、水和土壤等资源。4年来立体生态农业模式运行结果表明：立体生态农业使示范区的生态环境得到了良好改善,植被覆盖率由2000年的10%提高到2005年的50%-70%。农民年均纯收入也由实施前的632元上升到2005年的1 524元。与传统农业相比,立体生态农业更关注环境效益与经济效益的共赢。
The tri-dimensional eco-agriculture in Guohua Demonstration Area comprises ＂foodstuff crop-economic crop-pasture＂ pattern,＂fruit-herb＂ pattern and ＂ecological forest-pasture-livestock and poultry＂ pattern.These three eco-agriculture patterns make the most use of light,heat,water and soil in the peak-cluster depressions of Guohua.Analysis of a four-year tri-dimensional eco-agriculture pattern shows that the system greatly improves the ecological environment of Guohua Demonstration Area,vegetation coverage rate increases to 50% ~ 70% in 2005 from 10% in 2000.Annual net income of farmers rises from 632 yuan to 1 524 yuan in 2005.The tri-dimensional eco-agriculture greatly emphasizes on mutual beneficiality between the environment and economy when compared to traditional agriculture.
