摘要
对浦城寨下国有林场夕阳寺工区低立地级荒坡营造山杜英效果的定位调查表明：山杜英具有早期生长快、适应性强等特点，在低立地级荒坡树高年均生长量可达０．８１ｍ，胸径年均生长量可达０．９８ｃｍ，５年生林分总生物量可达１７．３０２７ｔ·ｈｍ－２；同时山杜英还具有改良土壤、提高水源涵养能力，为优良的荒山绿化树种。
The fixed position investigation of the effect of planting Elaeocarpus sylvestris on the waste hillside with the low site grade demonstrates that E.sylvestris possesses features of fast growth in the early stage,strong adaptivity,etc.,on the waste hillside with the low site grade its annual average height growth may reach 081m,its annual average dbh growth may reach 098cm,its total biomass of 5-year-old stands may reach 173027t per hm and meanwhile it also possesses capacities of improving the soil and raising the water conservation.It is an excellent greening species on waste mountains.
