海涂的草基渔塘模式研究

以江苏盐城海涂为研究对象，研究海涂草基渔塘模式的技术及实际运行效益，结果表明；海涂草基渔塘对改良海滨盐土十分有效，同时该模式经济效益也相当可观；在堤脚与集鱼沟之间种植芦苇有利于维护堤身安全；在塘内的一定量区域种植芦苇不仅提供一定数量的草食性鱼类饵料和净化鱼塘水质，还具有一定的缓冲海涂单纯养殖对环境造成的负面影响，最后，冬季排水捕鱼后，在塘内滩面上种植牧草对抑制滩面土壤返盐有显著效果。

Grass Dick Fish Pond in Tideland

The key technique and actual benefit of Grass Dick Fish Pond(GDFP)in tideland of east Jiangsu Province, China were studied in this paper. It is shown that GDFP could effectively reclaim saline land and bring big economic benefits. Phragmites communics planted between dyke|foot and fish|gathering ditch could ensure the safety of embankment wall; in fishpond it did not only provide forage for grass carp and purify water in fishpond, but also buffer unfavorable influence on environment resulted from fish culturing. Furthermore, after draining from fishpond for fishing in winter, grass cultured on land in fishpond could well prevent salt from accumulating on soil surface.
