• The result of the analysis shows that the landscape diversity is dominated and influcnced by cultivated land and wasteland; of the cultivated land and wasteland, the landscape fragmentation is high and the isolation low; of the salterns, and the rivers and ditches, the fragmentation is the lowest; and of the villages and towns and the mudflat the isolution is high due to their distribution

• 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
  研究过程中主要以1996年和2004年土地利用景观格局为基础，采用景观类型面积指数、景观破碎度、景观分离度、景观多样性指数、景观优势度、景观均匀度、景观形状指数分析区域土地利用景观格局变化特点。
• 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
  以甘肃省为例，基于景观生态学基础上，利用arcview和arc/info地理信息系统软件对甘肃省景观系统进行分类，结合景观指标计算软件fragstats计算出了甘肃省景观多样性指数(h)、优势度指数(d)、均匀度指数(e)、斑块分维数、聚集度指数以及斑块的破碎度指数。
• (2 ) region is mainly made up of large patches which are distributed collectively . region landscape is mainly made up of the hill grassplot landscape of mountainous region and desertification landscape . ( 3 ) with the enhancement of human beings effect, landscape diversity indexes are declined, landscape evenness indexes are reduced, and landscape fragmentations are intensified
  通过这些指数的分析表明：甘肃省以草地景观为主，斑块数较多，大小斑块间差异较大，斑块形状较复杂，自相似程度较低，区域总构形较复杂；区域总构形以大斑块为主体，呈聚集型分布，构成景观主体的是山地丘陵草地景观和裸地景观；随着人类干扰强度增加，景观多样性下降，均匀度降低，景观破碎化程度加深。
• 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
  将1986年的指数与2000年的指数进行比较发现，景观的多样性指数和优势度指数都增加了，分别由1.72增加到1.886和由0.193增加到0.359；而平均斑块面积和景观镶嵌度指数都减小了，分别由3.22减到3.103和27.361减为26.878。
