黄土高原地区不同立地条件的坡面其土壤水分状况有很大差异,利用这种差异来提高植被成活率已经成为黄土高原生态恢复建设的重要方向。采用探针式TDR对陕西省吴起县合家沟流域内不同立地类型的土壤含水量进行测定,然后用SPSS进行聚类分析,将17种立地类型聚为5类,并按照植被恢复的难易程度进行排序。建议对不同立地类型组配置与其相应的植被模式从而更加因地制宜的进行植被恢复建设。
The soil moisture status of slopes with different site conditions varies greatly in the Loess Plateau. Using this difference to improve the vegetation survival rate has become an important direction for the ecological restoration and construction of the Loess Plateau. The probe TDR was used to determine the soil moisture content of different site types in the Hejiagou watershed of Wuqi County, Shaanxi Province. Then the cluster analysis was conducted by SPSS, and the 17 site types were grouped into 5 categories. According to the degree of ease of vegetation restoration Sort. It is suggested that the different types of site groups should be configured with their corresponding vegetation models so as to make the vegetation restoration more appropriate to local conditions.
