摘    要:本研究采用目标层、准则层和指标层3级指标体系,从水文水资源、物理结构、水质、水生生物等方面对清水河流域的生态完整性进行评价,并分析其时空分布特性。结果表明,清水河干流生态完整性状况一般,其主要支流中,碧松就河为好,清平河、旧城河均为一般,高枧槽河分别为差、极差和一般状态;各河流生态完整性在时间和空间尺度上存在较大差异,总体上10月(秋季)优于4月(春季),受人类活动干扰相对较少的碧松就河、清平河、清水河上游及下游优于人类活动影响较大的旧城河、高枧槽河及清水河普者黑风景区段及丘北县城段。生态完整性评价清晰的诊断出导致河流健康问题的关键因子,可为今后清水河流域的水资源保护和合理开发利用提供参考。

关 键 词:清水河流域  生态完整性  指标体系  时空分布特征

Abstract:The ecological integrity of Qingshui River basin was evaluated using a combination of hydrology and water resources, physical structure, water quality and aquatic organisms. The index system included three layers: target layer, criterion layer and index layer. The spatial and temporal distribution of the ecological integrity was analyzed. The results showed that the ecological integrity of the Qingshui river main stream was in a state of general. In the main tributaries, BiSongJiu river was rated good, QingPing river and JiuCheng river were fair, GaoJianCao river was in state of very poor, poor and fair respectively. In addition, there was large difference of Ecological integrity in the temporal and spatial scales. On the whole, the ecological integrity in October (fall) was better than that in April (spring), and BiSongJiu river, QingPing river and the upper reaches of the QingShui river which were relatively less influenced by human activities were better than JiuCheng river, GaoJianCao river, PuZheHei and QiuBei of the QingShui river which were under more influence by human intervention. Ecological integrity evaluation plays an important role in river health problem diagnosis and the key factors estimate, which would provide helpful references for water resources protection and rational exploitation of Qingshui River basin in the future.
Keywords:Qingshui River basin  ecological integrity  indicator system  spatiotemporal difference
