Shuitu Baochi Xuebao, 2003 不同的亚流域划分对流域径流和泥沙负荷模拟的影响源于地形、土壤、土地利用以及气候特征输入的空间分布不均匀性。假设当亚流域划分充分考虑流域输入数据空间分布不均匀性时，流域模拟的输出结果趋于稳定，并应用分布式水文模型——SWAT作为研究工具，在GIS技术支持下，选择两个面积不同的流域采用不同的亚流域划分数量进行流域径流和泥沙负荷模拟。模拟结果表明，当亚流域划分数量达到一定水平时，增加亚流域划分对模型输出结果的影响较小，这在一定程度上证实了上述假设。在此基础上 ...

, 2012 分区边界的确定是生态分区的重要步骤,但目前多数水生态分区的边界确定以定性分析、专家判断为主。本研究以洱海流域为例,建立了一套两级分区体系。该体系基于GIS技术,用子流域作为分区基本单元,并用相关分析法,定量筛选一、二级分区指标。其中,一级分区指标为高程、坡度和植被归一化指数(NDVI),二级分区指标为农田百分比和城镇百分比。通过指标图层的叠加和重分类,合并同质性子流域,从而将洱海流域划分为5个一级区和9个二级区。藻类群落分布的验证结果表明分区合理。本研究将定量分析和子流域边界应用于水生态分区 ...
