中度干扰假说

中度干扰假说是物种多样性维持的一个重要理论。

Intermediate Disturbance Hypothesis is a major theory .

随着干扰强度的增加，群落物种的丰富度和多样性先升高后降低，结果支持中度干扰假说。

With the disturbance intensity increased , species richness and species diversity showed the trend of increase firstly , and then decreased , which supported the intermediate disturbance hypothesis ( IDH ) .

从生长期进入成熟期，根际土壤微生物丰富度、多样性及代谢活性均降低；不同生境芦苇根际微生物多样性及活力变化与中度干扰假说及边缘效应理论相符。

Between the growth season and the maturity season , the richness , diversity , and activity of rhizosphere microorganisms decreased ; Such variations in the community structures and activities of the rhizosphere microorganisms followed the rules of intermediate disturbance hypothesis and edge effect .

2级左右的中度干扰，多样性指数增高，符合生态学中度干扰假说理论，但完全未受人为干扰的多优种阔叶林多样性指数也高。

With the moderate disturbance of 2 degrees of the community , the diversity index value increased , which accorded with " Intermediate Disturbance Hypothesis " of ecology . But the diversity index of broad-leaved forests of dominant group species is high value .
