    Abstract:

    To evaluate the influence of different management measures on the water-holding capacity of Pinustabulaeformis Carr. plantation litter,the litter reserves,the maximum moisture,the natural moisture and the effective interception amount were measured and analyzed respectively at the time of tending beginning,tending after 2 years and tending after 4 years.During the process of experiment,the following five measures on Pinus tabulae formis Carr. plantation were used:clearing cutting with banding,banned tending,selective cutting with hole shape,branch pruning and introducing shrub,and with the not banned tending as a control group.The results showed that:(1)The litter reserves and moisture increased with the time.(2)Under the different management measures,the litter reserves after 2 years and 4 years followed as the sequence:clearing cutting with banding>banned tending>selective cutting with hole shape>branch pruning}introducing shrub>not banned tending;the maximum moisture of the litter after 1 to 2 years ranked as:introducing shrubs banned tending> clearing cutting with banding> selective cutting with hole shape>branch pruning,and after 2 to 4 years:introducing shrubs clearing cutting with banding> banned tending>selective cutting with hole shape>branch pruning>not banned tending;(3)The natural moisture of the litter after 1 to 2 years followed as:banned tending> introducing shrubs selective cutting with hole shape>clearing cutting with banding>branch pruning>not banned tending,and after 2 to 4 years:introducing shrub>banned tending>selective cutting with hole shape>clearing cutting with banding>branch pruning>not banned tending;(4)The effective interception amount ranked as:clearing cutting with banding>selective cutting with hole shape>introducing shrub>banned tending>branch pruning>not banned tending.
