摘　　要：16-20世纪中期珠江三角洲顶部的低塱区分布着面积广阔的湖沼湿地资源,这里的作物栽培及水生植物群落都具有鲜明的地域特色.明代以来随着堤围、闸窦修建,一部分低塱湿地区的得以进行农业开发.低塱区雨季内涝严重,当地农民根据低塱中积水深度的差异,分别种植浮水稻与深水稻,实行种稻与养鱼轮换的耕作制度.低塱区在种植深水稻与浮水稻的同时还起能起到滞洪纳洪作用.传统时代西、北江沿岸的低塱湿地中生物多样性极为丰富,低塱湿地湖泊和沿河岸的沙洲中都有丰富的水生植物资源,农家在这些地区也种植芡实、蒲草等经济水生植物.There were large areas of wetlands in the country of Gaoyao, Sanshui and Sihui in the Pearl River Delta region which were known as the district called Dilang. The Dilang were the wetlands that had been under agricultural utilization as low confining fields. With the construction of embankments sluices and, the development of Dilang area strengthened Since the 16th century. Because there are always serious flood and waterlogging during the rainy season, local farmers planted floating water rice and deep water according to the water depth in the wetlands. They also implied an farming system that rotated rice--growing with fish-feeding. The wetlands could stored much floods while growing rice of keeping fish in the rainy seasons. Thee were also many shallow lakes along the Xijiang river and Beijiang river which possessed extremely rich biodiversity. There were also many river sandbar resources in this district that had been growing large areas of water plants where the farmers cultivated kinds of aquatic plants or pastured the cattles.
