| 摘 要： | 运用景观生态学的原理和方法,采用景观优势度、植被生物量,以及景观多样性3个景观格局指数,从结构和稳定性两方面构建生态完整性综合指数,对丰满水电站库周生态完整性的动态变化进行评价. 结果表明,生态完整性综合指数从1979年的0.8698下降到2008年的0.8419,生态完整性没有根本性的改变,但恶化趋势明显.

| Abstract: | On the basis of the theory and method of landscape ecology, ecological integrity evaluation for the surroundings of Fengman hydropower station was carried out by using the landscape pattern index in terms of three aspects: landscape dominance, vegetation biomass, and landscape diversity. The results show that the comprehensive index value of the ecological integrity decreases to 0.8419(2008) from 0.8698(1979); the ecological integrity of this area has not been substantially changed; and the degradation trend is obvious. |
