解釋
一種景觀結構分析軟體-
Combining with fragstats software, landscape diversity index ( h ), landscape dominance index ( d ), landscape evenness index ( e ), fractal dimension, landscape contagion index and landscape fragmentation index are calculated. they show : ? grassplot landscape is a primary landscape type in gansu. the numbers of big patch is much more
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。 -
Computer - assisted analysis of landscape and evaluation is a new tendency of landscape ecology, famous analytical software fragstats can calculate as much as 40 landscape at one time, but until now no software is achieved for the purpose of assessing green landscape
應用計算機技術實現景觀分析和評價是近年來景觀生態學技術方法發展的一個新特點，國外有著名的景觀格局分析軟體fragstats ，它可以對多達40多個景觀指數進行計算。 -
The landscape pattern of change on the fraction of green vegetation during this period was studied using a landscape pattern analysis program fragstats by analyzing path size, number of patches, shape metrics and landscape heterogeneity metrics to show the changing feature of landscape pattern. all of these results of indices analysis emphasize that the eco - environmental system in beijing mountain area in a whole is stable and the fragmentation and heterogeneity level in the last five years is decreasing
本文在fcdmappingmodel原理和方法的基礎上，利用1994年和1999年的兩期landsattm數據，對北京北部山區昌平區、懷柔縣、密雲縣、平谷縣和西部山區門頭溝區的植被覆蓋率進行了計算，並利用fragstats軟體對其景觀變化過程從斑塊大小、數量、形狀和景觀異質性等角度進行了時空格局變化的剖析。 -
To capture some of the synoptic features of the landscape, several landscape pattern metrics ( i. e. landscape diversity index, landscape density index, and congregation index et al ) was calculated using the raster version of fragstats
選用景觀多樣性、景觀密度、聚集度等6個景觀參數，用fragstats景觀指數計算軟體進行計算分析，結果表明：景觀多樣性指數和均勻度指數都是沿梯度區呈增大的趨勢。
