乔木林地

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 .

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 .

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 .

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 .

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 ;

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 .
