richness index meaning in Chinese
富度指数
Examples
- Richness index , evenness index and diversity index were selected as indicators of pedodiversity . here we used shannon index ( h " ) as diversity index and pielou index ( e ) as evenness index
土壤多样性指数包括丰富度指数(特定区域内发育的土类数目) 、多样性指数( h )和均匀度指数( e ) 。 - Comparing with former prediction methods , there are two progresses in it . first , the concept of fracture richness index is advanced and thus extend of fracture ' s richness can be numerable
与以前的预测方法相比,本次论文在以下两个方面有了改进:第一,提出了裂缝发育指标的概念,从而能够对裂缝发育程度进行量化。 - The results showed that : from north - facing slope to south - facing slope and plain field , the species evenness and diversity index decreased ; from plain field to north - facing slope and south - facing slope , richness index also decreased
结果表明,当生境由阴坡向滩地到向阳坡变化时,各种多样性指数的变化顺序为,物种丰富度:滩地阴坡阳坡;均匀度和多样性指数:阴坡阳坡滩地。 - Biodiversity indices are much influenced by the types of the vegetation in jinfo mt . the species richness index , diversity index and evenness index of the plots in karst area raised when the plots were jamming early and slightly ; species richness index and diversity index of the plots in nonkarst area raised when the plots were jamming early and slightly , but evenness index fell . the diversity index and species richness index of original vegetation in karst area are lower than in nonkarst area
不同植被类型显著影响其生物多样性的变化,金佛山石灰岩地区植被在受到中轻度人为干扰初期,其物种丰富度和多样性、均匀度指数均有提高;砂页岩地区植被受到中轻度干扰,丰富度和多样性指数有所提高,均匀度指数呈相反趋势;石灰岩地区原生植被生物多样性和物种丰富度指数较砂页岩地区的原生植被低。 - Based on plant communities and plots investigation in jinfo mt . and experimental site in guilin , the author calculated the indices of every plot with its species richness index , simpson index , shannon - wiener index , pielou evenness index and alatalo evenness index . the author analyzed the character and variation of the biodiversity in different area and different layers about the plots in jinfo mt
1采用典型样方法,在金佛山和桂林实验场选取典型样地并做野外调查,分别计算各样地的物种丰富度指数、 simpson指数、 shannon - wiener指数、均匀度指数、 pielou均匀度指数、 alatalo均匀度指数,对金佛山不同地区样地生物多样性以及不同地区不同层次生物多样性特征和变化进行分析。
