灌木林地

随着生长年限增加，灌木林地土壤质量逐步得到改善。

The soil quality improved with the increase of shrub ages .

小流域内1m厚土壤有机碳、全氮和硝态氮主要分布在草地和灌木林地，同时沟道所占比例也比较大。

Most of the organic matter , total nitrogen and nitrate nitrogen content for the first meter in the watershed were distributed in the grassland , shrub land , and gully .

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 .

30～20cm天然草地和灌木林地的有机碳密度普遍偏高，而农地、果园和人工草地则均较低；

The organic C density of natural meadow and bush forest land is higher than farmland , artificial meadow and orchard at large in 0 ~ 20 cm ;

而20～40cm和0～40cm的土层内土壤有机碳密度相比之下灌木林地、农地和天然草地相差不大，而果园和人工草地相对较低。

While the organic C density of natural meadow , bush forest land and farmland is higher than artificial meadow and orchard in 20 ~ 40 cm and 0 ~ 40 cm .

灌木林地对于土壤氮素的积累功能较强；

Bush forest land had stronger accumulation function to soil nitrogen .

灌木林地在高程上的变化情况与前三种类型林地变化正好相反。

However , changes of shrub land in the elevation are quite on the contrary .

结果表明：灌木林地是干旱河谷的景观基质；

The results showed that shrub land was the landscape radix of the dry valley .

四种灌木林地土壤的物理性状明显优于荒坡地。

The soil physical properties of the bush forestlands are better than barren slope obviously .

灌木林地和草地对于土壤微结构的形成有促进作用；

Bush forest land and meadow had enhancing function to the formation of soil tiny structure .

各灌木林地不同土壤层内根系的生物量也存在一定的差异。

The root biomass in different soil layers also had certain discrepancy even in each bush forestland .

灌木林地和有林地的分布情况相似，数量均随海拔高度的增加呈上升趋势，但有林地上升幅度更大；

The quantity of shrubbery land and forest land is both increasing with the rise of elevation ;

林地的团聚体含量大于灌木林地、农地。

The content of Aggregates in the soil from forest land is more than Shrub Land and Farmland .

林地中，有林地和其他林地面积减少，灌木林地面积增加。

In Woodlands , forest land area and other wooded land area decreased , shrub forest area increased .

果园表层土壤的微结构水稳性最差，灌木林地和人工草地最好。

Tiny structure for water stability of orchard was worst , but bush forest land and artificial meadow were best .

不同的改造模式林分天然更新特征研究，对小陇山林区今后灌木林地改造具有一定借鉴意义。

The study of natural regeneration of shrub transformation model has significant to forest management of Xiaolongshan in the future .

土壤团聚体总量：天然草地>灌木林地>果园>农地>人工草地；

Soil total aggregate was shown as : natural meadow > bush forest land > orchard > farmland > artificial meadow .

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 .

土壤有机质：天然草地、灌木林地和农地含量较高，果园最低；

Soil organic substance was shown as higher content in natural meadow , bush forest land and farmland , orchard was lowest .

四级风险区主要分布在南部和中部地区的灌木林地、疏林地以及中覆盖度草地。

The forth-class risk zone locates the southern and middle area of shrub land , open woodland and the medium coverage grass land .

各土地利用类型的变化速度依次为其他林地水域疏林地未利用地灌木林地城乡用地有林地耕地。

The rate of change of land use was as followed : other woodland water open forest land unused shrub land Rural Land woodland arable land .

土壤水分变化相对较大，大小次序为：坝地>荒草地>灌木林地>坡耕地>林地>梯田。

For soil water content , that the tendency is : check-dam farmland > grassland > shrub land > slope farmland > woodland > terrace farmland .

从2000年以后，主要变化趋势是其他土地利用类型转向有林地和灌木林地，这主要是退耕还林的结果，土地利用类型向着更加理想的方向转移。

From 2000 onwards , the main trend is that other types of land use become forest and shrub land , which is mainly caused by returning farmland to forests .
