| 摘 要： | 基塘系统是一种相对封闭的人工生态系统，其鱼塘子系统中的营养盐－氮、磷既是鱼类生长的必需元素，又是水体中的限制性元素。氮、磷的变化受塘中水生生物活动（如光合作用、呼吸、排泄）、鱼类粪便、饲料投加、底泥等的影响，文中对基塘中氮磷的变化及影响因子进行探讨。

| Abstract: | The dike-pond ecosystem is a kind of relatively close ecosystem.Nitrogen and phosphorus ,which are the nutritional element in the fishpond,are both the necessary element for the fish growth and the limited element to the water qualyity.The variation of nitrogen and phosphorus are effected by activity of aquatic life,fish dejecta ,added forage,sediments ect.This paper discussed on the variation of nitrogen and phosphoru in the dike-pond ecosystem. |
