研究结果表明，不同森林带林分生产力差异显著，热带山地雨林产量最高，常绿季雨林稍次，山顶苔藓矮林最低；

The result showed that there are significant differences among these forest zones , of which the highest production occurs in the tropical mountain rain forest while the evergreen monsoon forest is lower and the least production appears in the dwarf mountainous woodland .

近百年来气候的明显变干引起了森林带土壤水分降低和植被带的南移，使过去确定的延安到秦岭北麓之间的落叶阔叶林带的中北部存在着一些自然的土壤干层；

In recent 100 years , obvious climate drying causes decrease of soil moisture and migration of vegetation to south and natural dried layers occur in the middle and north of the broadleaf trees between Yan ′ an and the northern Qinling Mountains .
