破碎度指数 meaning in English
landscape fragmentation index
Examples
- The indexes of diversity , evenness , dominance , isolation , fragmentation and fractal dimension are used in this study . the landscape structure evaluation was from three levels , which are sub - compartments , compartments and work region . used stores per square kilometer of forest and tm4 remote sensing image the author give the scaling analysis
根据中山陵森林资源调查数据，在分析其植被景观现状的基础之上，应用景观生态学原理，结合具体情况和考虑研究的可操作性，选取多样性指数、优势度指数、均匀度指数、分离度指数、破碎度指数、分维数指数6个指标，从地类景观要素、林分类型和小班三个层次，对中山陵景观进行结构评价初步分析。 - 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。 - In addition , by means of landscape diversity , evenness , dominance , fragmentation , fractal dimension and statistics , the author respectively analyzed landforms , plant , soil and so on in the original ecosystem of the typical dumping site , the damaged ecosystem and the rehabilitated ecosystem . in fact , landscape matrix has been completely converted from the original ecosystem to the rehabilitated ecosystem . the indexes of diversity , evenness and dominance in forest landscape have sharply increased , but segregation decreased , which demonstrates that the rehabilitated ecosystem has been a reasonable and fine artificial ecosystem under the control of human
在此研究的基础上，采用景观多样性指数、优势度指数、均匀度指数和破碎度指数，以及分维方法和统计分析相结合的方法，对矿区典型排土场的原生态系统、破坏后的生态系统、重建生态系统的地貌、植被、土壤等景观要素进行了分析，结果表明：从原生态系统到重建生态系统，景观基质发生了根本性的变化，林地的多样性、均匀性、优势度大幅度增加，分离度降低，显示了重建生态系统在人为的调控下，已初步形成一个结构较为合理、功能良好的人工复合生态系统。
