  1. 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。
  2. We use the landscape acreage index, landscape fragmentation index, landscape apartness index, landscape diversity index, landscape dominance index, landscape evenness index and landscape shape index, to analyze the characteristics of the changes of landscape based on the landscape structure in 1996 and 2004

    研究過程中主要以1996年和2004年土地利用景觀格局為基礎，採用景觀類型面積指數、景觀破碎度、景觀分離度、景觀多樣性指數、景觀優勢度、景觀均勻度、景觀形狀指數分析區域土地利用景觀格局變化特點。
  3. Based on the tm image translating of daxing district and quzhou county in 1986 ~ 2000, supported by the rs and gis software of erdas, arcview and supermap, landscape pattern index was calculated and analyzed. the result indicates that both the landscape diversity and the fragmentation index in study area are increasing, the aggregation index are decreasing. and the non - agricultural landscape tends increasing

    運用erdas 、 arcview 、 supermap等遙感與地理信息系統軟體，對大興區和曲周縣1986 、 1996 、 2000年三期tm影像進行解譯及空間分析，並計算景觀格局指數，研究結果表明：大興區和曲周縣在研究期內都表現出了景觀多樣性增加、破碎度增大，聚集度指數降低等特徵，而且非農業景觀均呈增加趨勢。
  4. The result shows that the area proportions of habitat landscape, industrial landscape, green - land landscape and water area landscape are 29. 57 %, 15. 423 %, 14. 501 % and 5. 98 % respectively in 2000. the number of landscape patch and diversity index of habitation is the highest and the fragmentation index of green - land landscape is the lowest in all landscape types

    結果表明， 2000年各景觀類型中，居住景觀和工業景觀的斑塊面積比例較大，分別為29 . 57和15 . 423 ，綠地景觀和水域景觀的比例偏小，分別為14 . 501和5 . 98 ；居住景觀的斑塊數和多樣性指數最大，綠地景觀的破碎度最小。
  5. Taking the land consolidation project of yizheng city in jiangsu province as an example, patch extension index, fractal dimension, diversity index, evenness index, dominance index, fragmentation index, corridor density, etc wee selected to analyze the characteristics of the landscape pattern before and after the land consolidation with the landscape ecology theory

    摘要運用景觀生態學理論方法，以江蘇省儀征市某土地整理項目為例，選取斑塊伸長指數、分維數、多樣性指數、均勻度指數、優勢度指數、破碎度指數、廊道密度等景觀指標，對項目區整理前後景觀格局特徵進行分析。
  6. By using the indexes of the landscape pattern : landscape diversity index, landscape dominance index, landscape fragmentation index, distribution centroid and extended dimension, the thesis presents the dynamic change of wetland spatial pattern from 1987 to 2002. the thesis is discussed from the following parts : part 1 : preface, the summary of the wetland study background and the wetland landscape pattern change study in home and overseas

    通過採用景觀多樣性指數、優勢度、景觀破碎化指數、分佈質心和擴展度等景觀空間格局指數，比較系統地分析了近20年豫境沿黃濕地景觀空間格局變化。本文包括以下八個部分：第一部分為引言，簡要回顧了濕地研究背景和國內外濕地景觀格局變化研究的狀況以及本文研究的意義。
  7. The landscape diversity index, dominance index, patch average area and patchiness have changed respectively from 1. 72 to 1. 886, 0. 139 to 0. 359, 3. 220 to 3. 103 and from 27. 361 to 26. 878 in different time from 1986 to 2000, which shows that the degree of landscape fragmentation has increased. such increase reflects severe interference of humankind. the result also shows that the spatial pattern of urban landscape has many problems such as unreasonable distribution, single configuration, reduced connectedness, increased fragmentation, decreased types of natural landscape and increased loss of soil and water

    將1986年的指數與2000年的指數進行比較發現，景觀的多樣性指數和優勢度指數都增加了，分別由1 . 72增加到1 . 886和由0 . 193增加到0 . 359 ；而平均斑塊面積和景觀鑲嵌度指數都減小了，分別由3 . 22減到3 . 103和27 . 361減為26 . 878 。
