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.
通過生態灌區理論,界定瞭灌區生態環境需水量的定義,明確瞭北方大型灌區生態環境需水量內涵.運用繫統動力學原理,構建瞭灌區生態環境需水量繫統動力學(SD)模型,併以陝西省寶鷄峽灌區為例,模擬計算瞭2005~2030年的灌區生態環境需水量.模擬結果錶明,寶鷄峽灌區生態環境需水量每年以6.08‰的速度增長,河流、植被、塘庫、城鎮4箇模塊的生態環境需水量都有較好的提高,促進灌區朝著生態灌區方嚮快速髮展.

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 demand 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.
