兰州南北两山生态环境建设决策支持模式初探

doi:10.7522/j.issn.1000-694X.2013.00036

摘要/Abstract

摘要：

兰州南北两山生态环境脆弱，自然状态下无法达到城市发展的绿化要求，必须进行生态环境建设。针对生态环境建设的决策困境，提出构建“决策支持系统+专家知识”的决策支持模式。在详细阐述此决策支持模式的基础上，以兰州南北两山作为研究案例，建立了兰州南北两山生态环境建设决策支持系统，通过该系统的试验结果讨论，最终给出兰州南北两山生态环境建设的两项用水措施建议，即： ①在多年平均降雨量大于400 mm的区域进行人工集雨；②在多年平均降雨量小于400 mm的区域进行人工灌溉(灌溉量相当于200 mm降雨)。最后结合专家知识形成兰州南北两山生态环境建设规划图，供决策者参考。

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
