摘  要:
介绍了我国低洼盐碱地生态开发区(以禹城市为例)的治理与开发现状,指出利用鱼塘-台田生态工程技术治理低洼盐碱地社会效益和经济效益明显,但由于存在水污染严重、水源保证率低、地下水资源利用率低;部分台田发生次生盐渍化,土壤养分失衡;传统农、渔业经济效益下滑等问题,影响了该地区的可持续发展。在对以上问题进行分析的基础上提出了相应对策。

摘  要:
It has been discovered that ecological engineering project with fish pond-terrace land is an effective model used to ameliorate low-lying alkali-land in China. Under man-control, it has been shown that significant economic, ecological and social benefits could be obtained in Yucheng city. Compared between 1989 and 1993, grain yield in terrace rose from 625 kg·667m-2 to 1 050 kg·667m-2 and adult fish yield rose from 571 kg·667m-2 to 710 kg·667 m-2, respectively. In order to promote the sustainable development of agriculture and aquaculture in the ecological areas in the fish pond-terrace land, some unfavorable factors are studied and some relative countermeasures are put forward.
