| 摘 要： | 文章以乌海市治沙林场森林资源规划设计调查数据为基础,分析了乌海市治沙林场的森林资源特点,参照全国森林资源连续清查关于森林生态功能的评价方法,评价了乌海市治沙林场的森林生态功能。结果表明:有林地树种丰富,起源均为人工,有17种优势树种,林龄较低;林场森林生态功能指数为0.41,生态功能等级处于“差”,成熟林生态功能指数最高,为0.44,发挥的生态功能最好,针叶纯林与阔叶纯林的生态功能最低,在以后的造林过程中,合理配置树种,营造混交林,对提高生态功能将发挥重要作用。

| Abstract: | Based on the investigation data of forest resources planning and design of Wuhai sand control forest farm,this paper analyzes the characteristics of forest resources of Wuhai sand control forest farm,and the forest ecological function of Wuhai sand control forest farm is evaluated by referring to the evaluation method of forest ecological function of national forest resources continuous inventory.The results show that the forest ecological function of Wuhai sand control forest farm is rich,the origin is artificial,there are 17 dominant tree species,and the forest age is low.The forest ecological function index of forest farm is 0.41,the ecological function grade is“poor”,and the ecological function index of mature forest is the highest,which is 0.44,the ecological function of coniferous pure forest and broadleaved pure forest is the best,and the ecological function of coniferous pure forest and broad-leaved pure forest is the lowest.In the process of afforestation,rational allocation of tree species and building mixed forest will play an important role in improving ecological function. |
