摘要
对嘉陵江流域南充金城山森林群落生物多样性的调查,揭示了各个样地的多样性指数与其生境具有相关性,由于所处环境条件比较接近,且人为影响严重,故该山森林群落的异质性差、植被组成单一,需加强对其保护.
On the basis Of field survey on biodiversity Of forest communities at Jincheng Mountain in Nanchongregion of Jialing River basin, the results show that the diversity indexes in different area are related to environmental factors.little environmental variation and violent disturbance from human being give rise to poor community heterogenity and unitarycommunity composition.It is very important to strengthen the protection.
