| 为探索火烧迹地生态修复的有效措施,以云南省玉溪市江川区“4·11”森林火灾后的火烧迹地为研究对象,结合遥感技术与实地调查,通过差异归一化燃烧比(dNBR) 量化火灾迹地损伤程度,将研究区域划分为未退化、轻度、中度和重度退化4个等级,针对不同退化等级及坡度条件,按“适地适树”原则设计恢复群落乡土树种配置方案,轻度退化区以自然修复为主,中度和重度退化区按照乔灌草藤分别为20%、30%、30%、20%的比例人工补种,陡坡按灌草藤分别30%、30%、40%的比例进行人工补种,以实现火烧迹地的快速生态修复。 |

| To explore effective ecological restoration measures for burned areas, the burned sites after the “4·11” forest fire in Jiangchuan District, Yuxi City, Yunnan Province were taken as research objects. Combined with remote sensing technology and field surveys, the differenced normalized burn ratio (dNBR) was adopted to quantify the damage degree of burned areas. The study area was classified into four degradation grades: non-degraded, lightly degraded, moderately degraded and severely degraded. In accordance with the principle of matching tree species to site conditions, native tree species allocation schemes for restored communities were formulated for different degradation grades and slope conditions. Natural restoration was prioritized in lightly degraded zones. Artificial replanting was carried out in moderately and severely degraded zones with the proportion of arbors, shrubs, herbs and lianas set at 20%, 30%, 30% and 20% respectively. For steep slopes, the replanting ratio of shrubs, herbs and lianas was adjusted to 30%, 30% and 40%, so as to realize rapid ecological restoration of burned areas. |
