  1. Diversity index on different terrain varied between 0. 28 to 1. 75, the terrain followed the sequence of level land - plain > sloping land - medium - gradient mountain > sloping land - medium - gradient hill > level land - valley floor > sloping land - medium - gradient escarpment zone > level land - depression > steep land - high - gradient mountain ; the evenness index on different terrain varied between

    發育于不同地形上的多樣性指數值范圍為0 . 28 1 . 75之間,從高到低依次為平原、中坡度、中坡度丘陵、山麓平原、中坡度峭壁帶、低洼地和高坡度山地;均勻度指數范圍為0 . 26 0 . 84之間,從高到低依次為中坡度、平原、山麓平原、中坡度丘陵、中坡度峭壁帶和低洼地。
  2. Study on horizontal gradient of birds diversity in winter in national natural reserve of beilun estuary

    北侖河口國家級自然保護區冬季鳥類多樣性水平梯度研究
  3. The result showed that landscape diversity index and evenness index increase along the gradient, whilst dominant index decrease along the gradient zones. in general, landscape elements present concentrative d istributing patterns for great size, with landscape patch density and edged density smaller and landscape heterogeneity lower than others within closing to gradient of the city

    優勢度指數呈相反的變化趨勢。在接近城市的梯度區內一般是景觀要素以大面積相對集中的分佈格局,景觀斑塊密度與邊緣密度較小,景觀異質性較低。越接近天然次生林區,景觀異質程度越大。
