| 摘 要： | 以太子河流域1992和2001年的土地利用数据和17个水文站点监测的径流数据为基础，借助GIS手段，运用景观格局指数分析方法和统计学方法，从景观水平和类型水平两个方面探讨景观格局变化对流域径流的影响。结果表明，太子河流域景观格局对径流过程有显著影响。在景观水平上面积加权平均分维数(FRAC_MN)、邻接度指数中位数(CONTIG_MD)和散布与并列指数(IJI)是影响径流的主要景观因子，其中面积加权平均分维数(FRAC_MN)对径流变化影响的显著性最大。在类型水平上旱地的斑块密度(PD)、旱地和建筑用地的面积加权平均分维数(FRAC_MN)和斑块连接度(COHESION)、林地和旱地的周长面积比变差系数(PARA_CV)和斑块聚集度指数(AI)、建筑用地的邻接度指数中位数(CONTIG_MD)和散布与并列指数(IJI)是影响径流的主要因子，其中林地的周长面积比变差系数(PARA_CV)和斑块聚集度指数(AI)对径流影响最显著。

| Abstract: | 17 hydrological stations located in the Taizi River basin were selected to investigate the relationship between landscape patterns and runoff using Ueographic Information System(UIS).Based on landscape patterns (landscape-level and class leve),landscape pattern index analysis and statistical methods were used to analyze the effects of landscape patterns on runoff.Results showed that the influence of landscape patterns on runoff was significant.At landscape level,the mean fractal dimension index(FRAC_MN),the median contiguity index(CONTIU_MD) and the interspersion and juxtaposition index(IJI) were the main pattern indices effectively affecting the runoff change.At class level,the patch diversity of dry land,the mean fractal dimension index(FRAC_MN) and the cohesion(COHESION)of dry land and residential construction land,the perimeter-area ratio variation coefficient(PARA_CV) and aggregation index(AI) of forest land and dryland,the median contiguity index(CONTIU_MD) and interspersion and juxtaposition index(IJI) of residential construction land were the main landscape pattern indices controlling the variation of runoff.Further-more,the perimeter-area ratio(PARA_CV) and the aggregation index(AI) of forest land were positively related to the change of runoff. |
