Estimation of postmortem interval using myofibril fragmentation index 利用肌原纤维小片化指数推断死亡时间
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 运用erdas 、 arcview 、 supermap等遥感与地理信息系统软件,对大兴区和曲周县1986 、 1996 、 2000年三期tm影像进行解译及空间分析,并计算景观格局指数,研究结果表明:大兴区和曲周县在研究期内都表现出了景观多样性增加、破碎度增大,聚集度指数降低等特征,而且非农业景观均呈增加趋势。
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 结果表明, 2000年各景观类型中,居住景观和工业景观的斑块面积比例较大,分别为29 . 57和15 . 423 ,绿地景观和水域景观的比例偏小,分别为14 . 501和5 . 98 ;居住景观的斑块数和多样性指数最大,绿地景观的破碎度最小。
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。
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 摘要运用景观生态学理论方法,以江苏省仪征市某土地整理项目为例,选取斑块伸长指数、分维数、多样性指数、均匀度指数、优势度指数、破碎度指数、廊道密度等景观指标,对项目区整理前后景观格局特征进行分析。
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。
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 通过采用景观多样性指数、优势度、景观破碎化指数、分布质心和扩展度等景观空间格局指数,比较系统地分析了近20年豫境沿黄湿地景观空间格局变化。本文包括以下八个部分:第一部分为引言,简要回顾了湿地研究背景和国内外湿地景观格局变化研究的状况以及本文研究的意义。
