摘　　要：马尾松(Pinus massoniana Lamb.)采脂林的经济收益一直倍受关注。该研究在广东信宜、河源和郁南3地建立了马尾松采脂试验林,分8个年度测定试验林的存活率、生长量及产脂力,并估算采脂林的经济收益。发现经济收益先逐年提高后缓慢下降,15 a采脂林经济收益可达9 583.5元/hm2.a,经济收益与存活率和产脂力紧密相关。该研究为投资造林企业和林农提供了重要参考。The economic benefits of resin-yielding stands of masson pine（Pinus massoniana Lamb.） always attract close attention.Three testing stands were established in Xinyi,Heyuan and Yunan,Guangdong for measurements of survival rates,growth increments and resin-yielding capacities.The economic benefits based on evaluation of 8 annual measurements displayed an early increase year-by-year and a later slow decrease.The annual benefit at 15 year reached 9 583.5 RMB per hectare.Additionally,the economic benefits are closely associated with the survival rates and resin-yielding capacities.These results provided an important guideline on the management of masson pine stands for the enterprises and local farmers.
