Abstract: In order to verify the relationship and regularity among the standing stock,pondage and nutrient accumulation of litter-fall layer of the planted Pinus massoniana forest of by different stand ages,the fixed sample sites of three stand ages were set up for planted Pinus massoniana forest located in Leli Forest Farm in Northwest Guangxi. The woodland litter-fall layer was measured. The results are as follows: (1)The standing stock is 3.31~5.64t/hm2 and the maximum net standing stock is 4.48~10.19t/hm2 from that zone litter-fall layer of the 9 to 14 years old planted Pinus massoniana forest,increasing with the increase of stand age .(2)The element nutrient accumulation amount of N、Ca in the forest land litter-fall layer is largest,each accounting for about ten different elements of the total nutrients of 1/3~1/2,respectively.The element content of Mg、K is the second,but Mn,Fe,P,Zn,Cu and B element content is a little.The total nutrient contents of the woodland litter-fall layer is 70.66~98.82kg/hm2,increasing with the increase of stand age .(3)There are great differences among the standing stock,the maximum net standing stock and the element nutrient total accumulation of forest land litter-fall layer,with the different regression equation .So,we can forecast the standing stock,the maximum net standing stock and the element nutrient total accumulation of forest land litter-fall layer by the different stand ages.

Key words: Pinus massoniana, planted young forest, litter-fall layer, hydrological characteristics, nutrient accumulation, Northwest Guangxi
