闽北杉木人工林密度控制连续状态的动态规划研究

收集闽北杉木人工林２４８块标准地资料，应用连续状态的动态规划方法建立了可变间伐间隔期的闽北杉木人工林种群密度决策模型．决策模型模拟表明该模型既反映闽北杉木人工林的种群密度，又符合杉木生长的一般规律，可应用于指导闽北杉木人工林的抚育间伐等生产实践．

Study on Cotrolling of Optimal Stand Density for Chinese Fir Plantation in Northern Fujian by Using Continuous Dynamic Programming

Based on the data collected from 248 sample plots in northern Fujian,the optimal stand density model of mobile thinning interval for Chinese fir (Cunninghamia lanceolata)plantation was built by using continuous state dynanic programming.The simulating results indicated that the model not only reflected the population density of Chinese fir plantation in northern Fujian,but also conformed to common growing law of Chinese fir,so that could be used to conduct forest production management such as thinning for Chinese fir plantation in northern Fujian.
