以甘肅省為例，基於景觀生態學基礎上，利用arcview和arc / info地理信息系統軟體對甘肅省景觀系統進行分類，結合景觀指標計算軟體fragstats計算出了甘肅省景觀多樣性指數（ h ） 、優勢度指數（ d ） 、均勻度指數（ e ） 、斑塊分維數、聚集度指數以及斑塊的破碎度指數。 -
We selected several landscape metrics, such as landscape diversity metrics, edge index, fractal dimension, evenness index, contagion index and so on
對綠洲-荒漠景觀的鑲嵌測定包括景觀多樣性、邊緣特徵、分維數、均勻度、分散度和蔓延度等。 -
The annual variation of runoff turned to uniform with the landscape patchiness index and landscape diversity index increased, and it turned to extreme with the landscape contagion index and landscape dominant index increased, and it did not relate to landscape shape index
隨著景觀破碎度和景觀多樣性的增大，流域徑流年內分配趨于均衡；而隨景觀聚集度的增大，流域徑流年內分配則趨向集中，景觀形狀對流域徑流調節作用不明顯。
