肇庆市应用基塘系统理论改造低洼地十年回顾(1980～1989)

REVIEW OF THE TEN-YEAR TRANSFORMING LOW-LYING LAND INTO DIKE-POND SYSTEM IN ZHAOQING MUNICIPALITY

本文通过实地调查,介绍了肇庆市自80年代初引入基塘系统理论改造低洼地,并在实践中拓展其应用领域的情况,分析了该市10年基塘生产的规模、效益和存在问题,最后提出了一些方向性建议。

There are about 58, 667 hm^2 (1hm^2=15mu) of low-lying land in Zhaoqing Municipality of Guangdong. At the beginning of the 1980 s, the dike-pong system was introduced into the municipality, and up till now some 6, 667 hm^2 of low-lying land have been transformed into dike-pond systems. The systems produce per year 150 million yuan of gross value of agricultural output for the municipality and 25,100 t of pondfish as well as a large quantity of fruits, duck eggs and pork supplied to market. From the practice, the local farmers have broadened the application field of the theory of dike-pond system. For example, they change the shallow bays of a reservoir into dike-pond system. Good benefits have been achieved in the 1ast ten years, but there are still some problems, such as lack in funds for completing the system. Some suggestions to solve the problems are put forward.
