摘要
近年来,随着城市化的不断推进,城市河流的生态系统出现破坏现象.目前多采用以生态分区为基础的区域生态环境管理和生态资源信息配置模式提供地理空间框架.深圳市茅洲河作为典型的城市污染河流,其生态分区可为城市生态资源管理及治理提供科学依据.本文针对茅洲河生态环境问题,提出城市河流实行"分项、分类、分区"三级划分体系.基于SPSS分层聚类分析技术,用水文、水质、河岸带及地貌和水生生物作为四大主要项目,构建涵盖各项目18个子指标的量化评分标准;通过对评分结果聚类,合并同质性子流域得出各项目的空间分类情况,并按照生态破坏程度将茅洲河流域分为一级生态红线区、二级生态黄线区及三级生态蓝线区.本文将聚类和定量分析运用于生态分区,为城市河流的治理提供新的方法.
In recent years,with the continuous development of urbanization,the ecosystem of urban rivers has been seriously damaged.The introduction of ecological zoning method is the key to restore river health,but most ecological zoning is not based on ecological restoration and management.Taking the Maozhou river basin in Shenzhen as an example,the research puts forward the threelevel division system of"suboption,classification and partition"of urban rivers.Based on SPSS hierarchical clustering analysis technology,taking hydrology,water quality,riparian zone,geomorphology and aquatic organisms as four main items,a quantitative scoring standard covering 18 sub-indexes of each project is constructed;through clustering the score results,the spatial classification of each project is obtained by combining homogenous sub-watersheds,and the Maozhou river basin is divided into first-class ecological red line area,second-level ecological yellow line area and third-level ecological blue line area according to the degree of ecological damage.In this study,clustering and quantitative analysis are applied to ecological zoning to provide a new method for the management of urban rivers.
