| 1. | In the study , the dominance index and evenness index are used for analysis 本研究采用优势度指数和均匀度指数进行分析。 |
| 2. | The dominance index is often contrary to the diversity index , index of diversification and evenness index in change rules 优势度指数常常与多样性指数、多样化指数、均匀度指数的变化规律相反。 |
| 3. | The intensive human disturbance within the region had increased the landscape diversity index and evenness index , a decrease of 从空间变化上看,土地利用变化主要集中在海拔2000m以下以及坡度15 35的区域。 |
| 4. | The t - test result shows that the species diversity index , evenness index and consume biomass are no significant differences between 12 years fore - and aft T检验结果表明,多样性指数、均匀性指数的消费生物量, 12年前后的差异不显著( p 0 。 01 ) 。 |
| 5. | We selected several landscape metrics , such as landscape diversity metrics , edge index , fractal dimension , evenness index , contagion index and so on 对绿洲-荒漠景观的镶嵌测定包括景观多样性、边缘特征、分维数、均匀度、分散度和蔓延度等。 |
| 6. | Analysis from the whole area the shape of landscape was becoming regular and simple . ( 4 ) the diversity index and evenness index decreased and the dominance index increased 从全区域尺度进行分析,景观形状趋于简单化、规则化,可见人类对该地区的管理活动是增强的。 |
| 7. | Richness index , evenness index and diversity index were selected as indicators of pedodiversity . here we used shannon index ( h " ) as diversity index and pielou index ( e ) as evenness index 土壤多样性指数包括丰富度指数(特定区域内发育的土类数目) 、多样性指数( h )和均匀度指数( e ) 。 |
| 8. | On the other hand , the high landscape diversity and evenness indexes owning to rich and well - proportional components are distinct features in the basin 整个植被景观体现出要素众多、间隔紧密、自然连接性好、景观破碎化程度较高的分布特征,同时也反映出类型丰富、比例协调、均匀性和多样性程度较高的总体特点。 |
| 9. | The decline of bird species diversity and evenness index in yueqing bay indicated that the habitats of water birds were being degraded , which might be related to human disturbance such as reclamation 鸟类多样性指数和均匀度指数均呈下降趋势,说明适宜水鸟栖息的整体资源环境正逐渐退化,这可能与围垦等人为干扰因素有关。 |
| 10. | The thesis used the diversity index , dominance index and evenness index to analyse the landscape patterns in the county , showing the embodying of the spatial characters caused by the man - made disturbance and landscape succession 接着,对柘荣县的景观格局进行分析。选用景观多样性指数、均匀度指数、优势福建拓荣县景观生态特征及景观生态规划的研究度指数对景观格局进行分析。 |
