| 摘 要： | 在利用Richards函数对湿地松生长进行拟合和利用动态规划方法在计算机上直接模拟抚育间伐的基础上，初步确定了江西省丘陵区湿地松多效益经营模式林分的采伐技术。研究结果表明：湿地松多效益经营模式林分始伐年龄为8．10年，主伐年龄为25年，最优抚育间伐方案为间伐3次(含始伐)，时间分别为第8、12及16年，间伐强度分别为每公顷950、700、300株，最后保留株数为每公顷550株。表2参7。

| Abstract: | The cutting technic for the Pinus elliottii plantation of the multi-benefit management pattern in the hilly region of Ji-angxi Province was studied by establishing the model of growth progress according to Richards function and simulating the tending cutting on computer by use of dynamic programming. The results showed that the best time for the initial thinning was at tree age of 8-10 and final cutting was at tree age of 25. The optimal thinning project was 3 times of thinning cutting including the first thinning, and the thinning time was at tree ages of 8, 12 and 16, respectively. Their thinning intensities were separately 950, 700 and 300 trunks per hectare, and the preserved density was 550 trunks per hectare until the final cutting |
