摘　　要：在大沙洼林场对已出现生长缓慢的成熟人工黑松林和水杉林进行了间伐、修枝、清灌等抚育改良试验,结果为抚育措施可以提高林地林木平均树高、胸径和材积、蓄积,降低灌木种类数量及其生长量,增加草本植物种类及其生长量,有效改善林地卫生状况和林木生长条件,延缓林地衰退,提高林地生产力和景观质量。该方法可以在本地及环境与林分相似地区推广。Forest degradation has happened in the pine forest of over 50a and metasequoia forest of over 40a. Thinning, pruning and shrub cleaning were conducted. The result showed that management practice has improved the average height of trees, DBH and stand volume, reduced the shrub diversity and growth, enhanced the diversity of grass and growth, effectively promoted the forest growth and mitigated the degradation. The management practice can be applied in other similar regions with similar stands.
