【摘要】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。更多还原

【Abstract】 The slope soil moisture of different site conditions have very great differences in the loess plateau.Using the difference of soil moisture content to improve the survival rate of vegetation has become an important method for the ecological restoration construction in this area.We used probe-type TDR to measure the soil water content of different site types in He valley of Wu Qi County,Shannxi Province,then clustered 17 kinds of site type to 5 categories by cluster analysis of SPSS and sorted it according to the difficulty level of vegetation restoration.We should configure corresponding vegetation patterns for different site types,thereby carry on the construction of vegetation restoration more suitable.更多还原
