| 摘 要： | 对云南金沙江流域受干扰退化后有代表性的天然植被类型进行调查，分析了导致天然林退化的干扰成因，探讨了该区域强度过伐林、恢复初期的天然次生林、疏林、灌木林以及破坏严重的退化生态系统的退化类型。把人为干扰程度分为微度干扰、轻度干扰、中度干扰和强度干扰等4个等级。对退化天然林类型进行划分，包括微度退化的林分24类，轻度退化的林分类型14类，中度退化林分14类，重度退化林分19类。表2参16

| Abstract: | In the Jinshajiang Watershed,degraded forestland,which included intensively-cut forests,early-restored secondary natural forestland,sparse forestland,brush land,and bare land,was analyzed after disturbance.Disturbance factors were divided into four grades of artificial interference and then ranked.Results of the four grades of disturbance showed:(a) 24 types of degraded forest stands were almost intact forests,(b) 14 types had slight-disturbance,(c) 14 types revealed mid-disturbance,and(d) 19 types showed intensive-disturbance.This grouping will help to better carry out protection of the Jinshajiang Watershed and ecosystem environmental management. |
