陕北黄土高原生态质量评价研究

Ecological quality assessment of Loess Plateau in northern Shaanxi

根据陕北黄土高原特殊的生态背景,并咨询专家意见,选取具有代表性的、可以综合反映该区域自然条件、人类活动干扰影响的指标来构建评价体系,并通过层次分析法计算各指标权重。通过对研究区生态质量背景、生态脆弱度、人类干扰度和人类适宜度的计算分类,最终算出研究区各县的生态质量综合评价值,并归为不同评价等级。以期为黄土高原区的可持续发展提供有益参考。

According to the special ecological background of Loess Plateau in northern Shaanxi,representative indexes reflecting the natural conditions in the region,the impact of human activities were selected to build a system for evaluation and analysis of the ecological quality. The quality of the ecological context of the study area, the fragile ecology,human interference and human fitness were calculated and sorted,and the comprehensive evaluation of the quality of the ecological values were obtained.
