| 摘 要： | 以森林资源一类清查数据为基础,利用人工神经网络的BP算法对山西省森林资源的发展趋势进行了预测。结果表明:山西省森林资源在相对稳定的条件下,森林面积、蓄积呈现稳定增长态势,森林生态功能逐步完善;到2010年森林覆盖率将达到21%;单位面积蓄积量呈明显下降趋势,森林生产力下降。此结果为研究区森林经营提供科学依据。

| Abstract: | The development trend of forest resources in Shanxi province was predicted based on the continuous forest resources check data by model of the artificial BP Neural Network.The result show that,under the relatively steady condition,the forest resources in area and volume are developing as a continuous and steady increase trend,ecological function of forestry is close to perfect.To 2010,the forest coverage rate will come to 21%.But unit area volume and forest productivity is declining.The result provides scientific foundation for the forestry management of studied area. |
