茫荡山自然保护区木质残体与群落物种多样性的关系

在森林生态系统中，木质残体是其重要的组成部分之一，在森林生态系统中有着不可替代的重要生态功能和景观生态意义。茫荡山自然保护区位于福建北部的南平，同时也是是杉木的中心产区，通过调查得出的木质残体的数量、材积，同时运用物种丰富度，Simpson指数，Meintosh指数，Fisher指数，Shannon-Wiener指数来反映木质残体其形成的独特生态功能，有助于研究森林生态系统的天然生态环境以及对自然保护区的了解，也为更合理的经营人工林提供研究支持。

The relationship between woody debris and species diversity in Mangdangshan Nature Reserve

In forest ecosystems, woody debris is one of the important component with an irreplaceably important ecological function and landscape ecological significance. ~angdangshan Nature Reserve is located in Nanping the north- em part of Fujian, and also is the center of fir areas. Through surveys of quantity and volume of woody debris, and use of species richness, Simpson index, Meintosh index, Fisher index and Shannon - Wiener index to reflect the unique ecological function formed by woody debris, it will be helpful to study the ecological environment of the forest ecosystems , understand on nature reserves, and also provide support for research on more reasonable business of plantatious.
