马尾松(Pinus massoniana Lamb.)采脂林的经济收益一直倍受关注。本研究在广东信宜、河源和郁南3地建立了马尾松采脂试验林，分8个年度测定了试验林的存活率、生长量及采脂力，并估算了采脂林的经济收益。发现经济收益先逐年提高后缓慢下降，15a采脂林经济收益可达638.9元/亩•年，经济收益与存活率和采脂力紧密相关。该研究为投资造林企业和农民提供了重要参考。

Abstract: |
|
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 of Guangdong province 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 15a reached 9583.5 RMB per hector. 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.
