摘要
军山湖原属鄱阳湖的一个子湖。１９５９年筑圩堤而分隔，洪水季节水面面积约２１３平方公里。现有水生维管束植物１９科２４属３１种；植被呈不规则环带状分布，主要有挺水、浮叶和沉水３个植物带、７个植物群落。水生植物平均生物量为每平方米１３１１克（湿重），全湖总生物量约为２７９６９４吨；产草食性鱼类的潜力为１１２３．４吨，折合每亩３．５１公斤。
Junshan Lake was one of son-lakes in Poyang Lake. In 1958, it was sparated by dams.It covers an area of about 213 square kilometres in flood-season.

The distribution of the plants exhibirs irregular zonation and it may be grouped into 3 plant zones and 7 communities. It has a peak average biomass of 1311g/m2(met weignt) during August. Annual production of aquatic vegetation in the entire lake area amouts to 279694 metric tons (wet weight).The capacity of herbivorous fish production is estmated at 1123.4 metric tons.
