| Abstract: |
| In Heidaigou Mining Area of Inner Mongolia, we adopted drying method to measure soil weight moisture of reclaimed land with different vegetations to calculate soil water storage. Based on the above data, we also used SAS9.0 for ANOVA and CLASSIFY analysis. The results showed that: the
soil with mixed vegetations had higher soil weight moisture, 15 a Hippophae hymnodies + willow was the highest, and soil water storage capacity of vegetatio
ns was followed by 10 a Siberian Apricot + Hippophae hymnodies and 2 a Amorpha fruticosa L.+ Syringa oblata + Pinus tabulaeformis Carr., which increased soil water storage by 48.7%, 45.6% and 32.3%, respectively compared with bare arable land. Single vegetation's soil water storage was cut down, such as 2 a Robinia hispida L., 2 a Prunus humilis Bunge and 5 a Alfalfa, which reduced soil moisture by 2.6%, 2.8% and 9.9% respectively compared with bare arable land. Through the shortest distance cluster analysis classification of soil water storage, we believe that the composite model should be taken in mining reclaimed land, and the main vegetations are Hippophae hymnodies, Alfalfa and Siberian apricot. |
