摘要
在对粤西茂名市的基塘复合生态系统进行面上调查和定点分析基础上,笔者对具有地方特色的典型基塘系统模式,即凼仔养鱼生态模式和鱼畜果生态模式进行了研究,分析了它们的结构功能和生态经济效益,并就这两种生态模式的完善和推广作了讨论。
Through regional investigation and site analyses, typical chinampa systems in Maoming city of Guangdong province were studied. Apart from the common chinamapa system model, there arc the traditional tiny fish pond model and fish-livestock-fruit model. Traditional tiny fish pond model can make good use of the favourable conditions of the forest area, and vegetables and other crops arc planted by pond. It is easy to manage the tiny pond, and the fish yield is often above 1000kg/inu. At present, deforestation and water pollution arc the two major factors to retard the development of this system in the studied area. Fish-livestock-fruit integrated system has a close material cycling, which has a good social, economical and ecological benefit.
