大斑 meaning in Chinese
great red spot
Examples
- Separation and preparation of mycotoxins from exserohilum turcicum by high performance liquid chromatography
高效液相色谱对玉米大斑病菌毒素的分离与制备 - The proportions of large , middle and small patches were small patch > middle patch > large patch in all gradient zones . from suburbs to secondary forests , the area ratio of middle and small patches was increased , but that of large patches was significantly decreased
大、中、小斑块的数量比例在各梯度区之间都是小斑块数量比中斑块数量比大斑块数量比。沿城区到天然次生林区方向，中小斑块的面积百分比逐渐增大，而大斑块则呈明显的下降趋势。 - The mutation , contrast and heterogeneity of ecological interface between oasis and desert ecosystem increased . rare natural or non - regional mosaic of patch show obvious sensitivity to spatial scale , the change ratios of theirs area and perimeter are greater than large patch
同时通过测度敏感性检验，表明在尺度变换中，稀少的自然或隐域性斑块镶嵌体对空间尺度敏感性大，面积、周长等变化率大于大斑块，随尺度中度干扰则合并成较大的斑块，随尺度强烈干扰或隔离加强后最先消失。 - ( 2 ) region is mainly made up of large patches which are distributed collectively . region landscape is mainly made up of the hill grassplot landscape of mountainous region and desertification landscape . ( 3 ) with the enhancement of human beings effect , landscape diversity indexes are declined , landscape evenness indexes are reduced , and landscape fragmentations are intensified
通过这些指数的分析表明：甘肃省以草地景观为主，斑块数较多，大小斑块间差异较大，斑块形状较复杂，自相似程度较低，区域总构形较复杂；区域总构形以大斑块为主体，呈聚集型分布，构成景观主体的是山地丘陵草地景观和裸地景观；随着人类干扰强度增加，景观多样性下降，均匀度降低，景观破碎化程度加深。 - The shape of patches is somewhat related to their distributing way . on the two sides of a valley , the shapes are mainly long and narrow ; while the shapes of small patches are more similar to round . furthermore , the fractals show that the forest landscape is interfered quite greatly by human activities
研究表明，景观斑块的形状与它的分布方式有一定的关系，沿沟谷两侧的山坡分布的斑块形状以狭长为主，且数量较多；而镶嵌于大斑块中的小斑块的形状更接近于圆形，且数量较少。
