gradient zone meaning in English
梯度带
Examples
- The deposit is regional located in the place of the sudden changing of gravity - gradient zone in the direction and intensity . the area also shows high geochemical background of au , ag , as , sb and hg elements
区域上矿床处于重力梯度转向及其梯度值突变部位，有au 、 ag 、 as 、 sb 、 hg等元素的地球化学高背景区。 - 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 result showed that landscape diversity index and evenness index increase along the gradient , whilst dominant index decrease along the gradient zones . in general , landscape elements present concentrative d istributing patterns for great size , with landscape patch density and edged density smaller and landscape heterogeneity lower than others within closing to gradient of the city
优势度指数呈相反的变化趋势。在接近城市的梯度区内一般是景观要素以大面积相对集中的分布格局，景观斑块密度与边缘密度较小，景观异质性较低。越接近天然次生林区，景观异质程度越大。
