| 中文摘要: |
| 通过生态灌区理论，界定了灌区生态环境需水量的定义，明确了北方大型灌区生态环境需水量内涵。运用系统动力学原理，构建了灌区生态环境
需水量系统动力学（SD）模型，并以陕西省宝鸡峡灌区为例，模拟计算了2005～2030年的灌区生态环境需水量。模拟结果表明，宝鸡峡灌区生态环境需水量每年以6.08‰的速度增长，河流、植被、塘库、城镇4个模块的生态环境需水量都有较好的提高，促进灌区朝着生态灌区方向快速发展。 |

| Based on the theory of ecological irrigation district, this paper discussed the contents of the northern large-scale irrigation districts' water requirement for eco-environment, and defined it for the maintenance of healthy water requirement for irrigation districts' ecosystem. Using the system dynamics approach, it constructed a system dynamics（SD） model of water requirement for eco-environment of irrigation districts. Taking Baojixia Irrigation District in Shaanxi Province as an example, it also simulated the water de
mand for its eco-environment from 2005 to 2030. The results show that the water demand for ecological environment in Baojixia irrigation district increases at the rate of 6.08‰ per year. And this irrigated area is developing in the same direction as an eco-irrigation district. |
