植物群落的内禀冗余

植物落处于各种扰动之中，扰动导致群落的总体功能降低，为适应各种形式的扰动，群落的功能补偿作用就发生了，并由此产生了生长冗余，组分冗余及内颤冗余，内禀冗余是植物群落中组分冗余的一种特殊形式，是对波动的环境及人为或动物扰动适应的结果，是落功能最大化的产物，内禀冗余的作用是使群落多样性，物种多样性得以保持，使群落对各种扰动的抵抗能力增强，在一定条件下，内禀冗余阻碍了群落中当前有益物种产量最大限度地实现，但从生态学观点看，它对植物群落中目标物种的持续较高水平的输出具有重要作用，因此，保留以内禀冗余形式存在的非目标植物种对群落的稳定是有益的。

Intrinsic redundancy in plant communities

Plant communities and their plants' species exist in various disturbances, which result in decline of total function of plant communities. For adapting the various disturbances, compensation process occurs, and in the case growth, compositional and intrinsic redundancies take place. There are some intrinsic and structural redundancies exist in plant communities, in which intrinsic redundancy plays an important role in the protection of biodiversity, tolerance from disturbance and the maintenance of the stability of plant communities. Acting as one way of redundancy, intrinsic redundancy obstructs the realization of plant communities' maximum function, however, its existence in plant communities maks it possible for higher and stable output of plant communities. So it may be helpful to the mankind to keep some plant species that exist in intrinsic redundancy in the plant communities.
