    摘要:

    植物群落密度调控是生态学领域的研究热点。从Yoda提出-3/2自疏法则以来,围绕植物群落密度调控规律从自疏线可变性、环境因素对密度调控影响的规律等进行了大量研究。尤其是基于代谢生态学理论建立的WBE自疏规律提出后,密度调控规律的争论和研究更为活跃,其焦点主要是自疏线斜率是否存在相对恒定的α值和值的大小\.根据国内外文献,综述了-3/2自疏法则、-4/3自疏法则、质量-密度的等速比例关系和环境对密度调控规律的影响等方面的研究,指出密度调控的机制以及胁迫条件下的密度调控及其应用是未来研究的趋势。

    Abstract:

    Plant biomass-density relationship (B-D) has been one of the hot spots in ecology. Since Yoda′s the -3/2 power law of self-thinning, studies focusing on B-D relationship in plant ecology have been conducted to elucidate the variability of self-thinning line and the effects of environments. The recent developed WBE model that the metabolic theory of ecology was applied to self-thinning law arose highly debates. The major questions addressed were whether slope of self-thinning line (α) is constant (-3/2 or -4/3) and how environment influences B-D relationship. In this paper we reviewed recent researches on -3/2 self-thinning law, -4/3 self-thinning law, isometric scaling of biomass-density and effects of environments on B-D relationship. It suggested that B-D relationship under stress environment and mechanisms of B-D relationship needed further studies.
