摘要
目的初步分析计算陕北地区的各生态系统生态环境需水的数量及功能。方法通过对陕北地区不同生态系统的界定,计算了河道内外生态环境需水量,并考虑到“一水多用”的特性,得出了陕北地区生态环境需水量的概算值。结果得出陕北地区生态环境需水量的概算值为22.55×108m3,约相当于陕北地区水资源总量的50.5%。结论针对陕北地区生态环境十分脆弱这一特点,认为解决陕北地区的生态问题应从加强对生态环境需水问题的研究入手。
Aim To analyze the function of the water resource in north of Shannxi area and evaluate the consumption for eco - environmental water of different kinds of eco-systems. Methods The consumption for eco-environmental water both in river way and out of it is evaluated. Results The total consumption is 22.55×10^8m^3, which is equal to 50.5% of the total summation of the water resource in north of Shannxi. Conclusion The problem of the eco-environmental water should be seriously delt with in order to solve the ecological problems in this area.
