- Abstract:
-
Compared with mixed forest,moisture retention power of litter,characteristics of soil hydrologic-physical properties and soil infiltration of 35-year different canopy density Larix Principis-rupprechtⅡ man-made forest in north mountain of Hebei province are studied.The results showed that available impoundage of litter,total porosity,capillary impoundage,non-capillary impoundage,total impoundage,start infiltration speed rate and stable infiltration speed rate of soil in mixed forest are better effect than man-made forest.These are reduced with canopy density lowering.Maximum moisture holding capacity and available moisture holding capacity of litter was 4.45~48.02t/hm2 and 3.19~35.97t/hm2.Total impoundage of forest land increased with canopy density raised.Total impoundage of woodland in mixed forest was maximal (1121.68t/hm2).The soil water storage quantity accounts for the total water-holding capacity above 95%,water conservation function by soil level primarily.The results showed that water conservation function was low in Larix Principis-rupprechtⅡ man-made forest.
