- Abstract:
-
Based on field sampling and indoor determination, together with statistical analysis, soil erodobility of 7 land utilization types in dry-hot valley in Jinsha River was studied. Results indicated that in dry-hot valley, after the forest land of Camptotheca acuminate was changed to other land types, content of soil organic matter (SOM), total nitrogen (TN), total phosphorus (TP) and available nitrogen (AN) in soil on the other lands decreased obviously, available phosphorus (AP) and soil bulk density changed little, while available potassium increased a little. Generally, the impact on soil physic-chemical properties was relatively small after transforming to leucocephala land and abandoned grassland. Compared to the forest land of Camptotheca acuminate, soil erodibility on the other land types increased obviously, which was followed in the order:pepper land Leucaenaland
