Estimation of postmortem interval using myofibril fragmentation index 利用肌原纖維小片化指數(shù)推斷死亡時(shí)間
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(yùn)用erdas 、 arcview 、 supermap等遙感與地理信息系統(tǒng)軟件,對大興區(qū)和曲周縣1986 、 1996 、 2000年三期tm影像進(jìn)行解譯及空間分析,并計(jì)算景觀格局指數(shù),研究結(jié)果表明:大興區(qū)和曲周縣在研究期內(nèi)都表現(xiàn)出了景觀多樣性增加、破碎度增大,聚集度指數(shù)降低等特征,而且非農(nóng)業(yè)景觀均呈增加趨勢。
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(jié)果表明, 2000年各景觀類型中,居住景觀和工業(yè)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(shù)和多樣性指數(shù)最大,綠地景觀的破碎度最小。
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 研究過程中主要以1996年和2004年土地利用景觀格局為基礎(chǔ),采用景觀類型面積指數(shù)、景觀破碎度、景觀分離度、景觀多樣性指數(shù)、景觀優(yōu)勢度、景觀均勻度、景觀形狀指數(shù)分析區(qū)域土地利用景觀格局變化特點(diǎn)。
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(yùn)用景觀生態(tài)學(xué)理論方法,以江蘇省儀征市某土地整理項(xiàng)目為例,選取斑塊伸長指數(shù)、分維數(shù)、多樣性指數(shù)、均勻度指數(shù)、優(yōu)勢度指數(shù)、破碎度指數(shù)、廊道密度等景觀指標(biāo),對項(xiàng)目區(qū)整理前后景觀格局特征進(jìn)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 以甘肅省為例,基于景觀生態(tài)學(xué)基礎(chǔ)上,利用arcview和arc / info地理信息系統(tǒng)軟件對甘肅省景觀系統(tǒng)進(jìn)行分類,結(jié)合景觀指標(biāo)計(jì)算軟件fragstats計(jì)算出了甘肅省景觀多樣性指數(shù)( h ) 、優(yōu)勢度指數(shù)( d ) 、均勻度指數(shù)( e ) 、斑塊分維數(shù)、聚集度指數(shù)以及斑塊的破碎度指數(shù)。
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 通過采用景觀多樣性指數(shù)、優(yōu)勢度、景觀破碎化指數(shù)、分布質(zhì)心和擴(kuò)展度等景觀空間格局指數(shù),比較系統(tǒng)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(gè)部分:第一部分為引言,簡要回顧了濕地研究背景和國內(nèi)外濕地景觀格局變化研究的狀況以及本文研究的意義。
