| 摘 要： | 森林粗木质残体是指森林中林木生长的竞争排斥、老龄林内树木自然死亡、自然干扰(风倒、火灾、雨淋、雪折、病虫害、泥石流灾害、真菌侵害等)以及人为干扰(伐木、砍樵)等而形成。从粗木质残体的概念及其类型,以及森林生态系统中生产者、消费者、分解者的营养结构等方面综述了粗木质残体的功能。根据国内外对粗木质残体的研究情况详细论述了其研究方法,并对我国森林粗木质残体的研究进行了展望。

| Abstract: | Coarse woody debris(CWD) can be produced under situations of growth competition of trees,natural death of forest at old stage,natural interferences(wind,rain,snow,fire,lightning,insect,debris flow,invasion of fungi,etc.) and human interferences(logging,hacking trees).The concept and types of CWD were described,and functions of CWD were summarized from the nutrient structure of the producers,consumers and decomposers in forest ecosystems.In addition,research methods of CWD were discussed in detail.Finally,th... |
