人工绿洲防护林体系稳定性评价——以景泰县引黄灌区绿洲防护林体系为例

摘要/Abstract

摘要： 通过引水灌溉发展起来的人工绿洲是干旱区社会经济发展的主要依托。稳定的人工绿洲防护林体系是绿洲稳定的前提条件。根据人工绿洲防护林体系稳定性的含义和实质，构建评价其稳定性的指标体系，该指标体系由4个层次19个评估因子组成；通过分级量化指标；用层次分析法对指标进行权重分析；提出了人工绿洲防护林体系稳定性评判标准和具体的评判方法。以甘肃景泰县引黄灌区人工绿洲为例，对其防护林体系稳定性进行评判，结果与实际基本相符，说明本评价方法具有应用价值。

Abstract: Artificial oasis developed by irrigation through channeling water is the backing of development of society and economy in arid area. Stable protection forest system of the artificial oasis is the essential prerequisite for the oasis stability. Based on the meaning and substance of the stability of artificial oasis protection forest system, the indicator system composed of 4 hierarchies including 19 factors to evaluate the stability were erected. The indicators were quantified by classification method, and the weight values of all factors were calculated by the method of analytic hierarchy process (AHP). At the same time, the criterion and the specific method were defined to judge the stability of the protection forest system in artificial oasis. The protection forest of the typical artificial oasis developed by irrigation through channeling water from the Yellow River in Jingtai county Gansu province was taken as an example to test the evaluation system. The result basically conformed to the reality.

Key words: stability, evaluation, protection forest system, artificial oasis, indicator system
