Abstract  

Artificially ecological environment construction is the necessary approach to greening Lanzhou City due to fragile natural environment. This paper proposed a decision support model which was comprised of "decision support system" and "expert's knowledge". Based on introduction of the decision support model, we developed a decision support system for ecological environment construction in the southern and northern mountains of Lanzhou City. Through discussing the experimental results of the decision support system, a water conservancy scheme for ecological environment construction in the southern and northern mountains of Lanzhou City was presented as below: (1) Collecting rainwater for environmental construction in the area where the average annual rainfall exceeds 400 mm; (2) Operating irrigation in the area where the average annual rainfall is below 400 mm, and the irrigation amount equals to 200 mm rainfall. Furthermore, a planning map for ecological environment construction in the southern and northern mountains of Lanzhou City is demonstrated to assist decision makers.

Key words:  ecological environment construction      decision support system      southern and northern mountains of Lanzhou City
