乔木林地乔木林地
  1. 乔木林地、灌木林地和草地>5mm的团聚体平均达到了340g。

    Arboreal woodland , the cluster > 5mm in shrubby woodland and meadow average reach 340g .

  2. 土壤含水量为:乔木林地>灌木林地>农地。

    The contents of soil moisture were arranged in the following sequnce : forest land > bush land > farm land .

  3. 非毛管孔隙度则是退耕地乔木林地天然灌丛天然草地。

    For the non-capillary porosity , its order from high to low was abandoned farmland , woodland , shrub land , and grassland .

  4. 结果表明:林草复合措施植被恢复效果最好,灌木林地植被恢复优于乔木林地,杨树纯林地效果较差;

    The results showed that the integrated tree-grass planting had the best effect on vegetation restoration . The vegetation restoration on shrub land was better than that on high tree land .

  5. 表层土壤粗粉粒平均含量为:灌木林地>乔木林地,低龄林地>中龄林地>高龄林地,中粉粒与细粉粒之和则是相反;

    Average contents of coarse silt in the top layer of the soil were appeared in the following order : bush land > forest land , young stands > middle-aged stands > mature stands while the total contents of medium and fine silt were adversely ;

  6. 4种植被类型0~30cm土层的土壤密度为天然灌丛天然草地乔木林地退耕地;

    By comparing the averaged soil physical properties of upper soil layer ( 0 ~ 30 cm ) among four main vegetation types , the soil density in abandoned farmland was the highest , the woodland the second , the grassland the third , and the shrub land the lowest .
