种群密度制约原理在生态恢复中应用的思考

种群密度制约是种群自我调节的重要机制，是生态学的重要原理之一，而且被列为恢复生态学的重要原理之一。现有资料表明：该原理在国内的研究多处于证明阶段，缺乏实际应用。本文分析了不同生态恢复途径下如何应用种群密度制约原理，认为：在人工重建生态系统时，应该注意种群的合理密度；在实施自然恢复的生态系统中，应该增加人类活动的积极干扰，控制植物种群的密度，使植被得以快速恢复。

Reflection on the Application of the principle of Density Dependent in Ecological Restoration

Density dependent is an important mechanism of the creature community self-adjustment,and an important principle in ecology.Recently,the restoration ecology is paid more and more attention by scholars and governments;they believe thart the density dependent is an important principle.But a lot of data show that the principle has not yet been safficiently applied to the practice,This article provides some discussions about the issue.We get the conclusion that different model of ecological restoration shoald be matched with different density.
