| 摘 要： | 为厘清汉江水体鱼类集约养殖与生态负荷量的关系，测定安康库区滤食性鱼类天然鱼产力，测算Ⅱ类水质限定条件下的安康库区生态负荷量，并与以水体磷含量为标准的计算结果比较。结果表明，设定网箱深度3 m，单位水体生态负荷量为193.44 g/m3，总产量控制为10.47×104 t。库区网养单产为100 kg/m3时，网箱养殖面积控制为1.93‰，网箱生态养殖面积与单位面积产量呈反比。

| Abstract: | The ecological fish load were calculated under the condition of class II water quality, according to the yield of filter fish in the reservoir area of Ankang and in a proportion of 1 to 3, and to comparison of the calculation results with the phosphorus content in water. Results show, set the cage depth 3m, the unit of water ecological fish carrying capacity is 193.44g/m3, the total output control for 10.47t × 104 in reservoir area of An-kang. When the net raising yield is 100kg/m3, the control area is 1.93 per thousand, and the yield per unit area is inversely proportional to the ecological farming area. |
