自然干扰 meaning in English
natural interference
Examples
- The higher landscape heterogeneity , the closer to nature secondary forest . along the gradient , landscape congregation index exhibits descendent tendency , showing a significant relationship between the extent of patch mosaic and the extent of disturbance , according to changes of landscape mean shape index ( lmsi ) and landscape mean fractal dimension index , integrated disturbance ( nature disturbance , human activities , vegetational inner succession or population dynamics ) tend to enhance
景观聚集度指数是随着梯度区呈下降的变化趋势，表明斑块之间的镶嵌联系的程度与受到的干扰程度有极为重要的关系。从景观平均形状指数和景观平均分维数的变化，可看出综合干扰(自然干扰、人为活动、植被的内源演替或种群的动态变化)是呈增强的发展趋势。 - The wetland habitats for many wild animals were seriously affected by this change and the habitat pattern had an obvious change , too . the area of suitable habitat ( sd 0 . 35 ) , which had reduced by 7637 hm2 in the ten years , was becoming smaller and more fragmented , with deteriorated quality . for red - crowned cranes , the area with high spatial diversity values ( sd 0 . 65 ) and that with mid - high values ( 0 . 5 sd < 0 . 65 ) , which constituted the main part of suitable habitat of red - crowned cranes , had reduced by 9232 hm2 and 15584 hm2 respectively , with the shrinking of natural land cover , such as reed and suaeda
研究区野生动物生境格局受人为和自然干扰的双重影响而发生了较为明显的变化，整体趋势是生境适宜性逐渐降低，适宜生境和较适宜生境( sd 0 . 35 )的面积十年间减少7637hm ~ 2 ，丹顶鹤的适宜生境( sd 0 . 65 )和较适宜生境( 0 . 5 d < 0 . 65 )面积分别减少9232hm ~ 2和15584hm ~ 2 ，且生境的破碎化程度加深，在空间上呈现由北向南海向推进、由东向西压缩之势，生境质量呈下降趋势。
