| 摘 要： | 城郊荒地是一类极其宝贵的农业自然资源,它的开发和利用日趋为人们所重视.本文阐述了天津市荒地改良生态农业示范区通过对荒地实施生态工程建设,建立起以“基塘型果园”为景观特征.以“果——鱼——畜——禽”为生产主线的复合农业生态系统,使荒地资源发挥了巨大的生产潜力;并对该荒改示范区农业生态系统的结构合理性与功能有效性进行了分析与评价,旨在探讨城郊荒地改良模式和调控途径.

| Abstract: | Uncultivated land is a kind of valuable agricultural resources ,especially in suburbs. In order to bring the potential of uncultivated land into full paly,we built a model of compound agroecosystem by eco-engineering construction in the experiment plot. The model have landscape features of "fruit orchard-fish pond "and have production structure of 'fruit-fish-domestic animal-domestic bird". In this paper also analyses the structure and function of the agroecosystem in order to approach the model and control method of uncultivated land improvement in suburbs. |
