摘  要:
以“数字流域”为平台,采用SPSS统计软件,利用主成分分析和聚类分析方法进行了流域土地质量等级评价。综合运用“数字流域”信息和相关软件进行土地评价,不但可以精确筛选因子、确定权重、计算分值,而且能够实现数字成图和空间数据分析,为土地规划及流域综合治理提供先进技术方法,具有实用价值和现实性意义。

摘  要:
Supported by the theory of digital watershed,statistic software SPSS was used to assess the land quality by the methods of principal component and clustering analysis.Application of the knowledge about digital watershed together with related software in assessment of land quality has great advantage on selecting the factors,confirming the power,calculating the value and analyzing the spatial data,which can offer the advanced technology and method for land planning and watershed management and has important practical meaning.
