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 區域上礦床處于重力梯度轉向及其梯度值突變部位,有au 、 ag 、 as 、 sb 、 hg等元素的地球化學高背景區。
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、小斑塊的數量比例在各梯度區之間都是小斑塊數量比中斑塊數量比大斑塊數量比。沿城區到天然次生林區方向,中小斑塊的面積百分比逐漸增大,而大斑塊則呈明顯的下降趨勢。
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 優勢度指數呈相反的變化趨勢。在接近城市的梯度區內一般是景觀要素以大面積相對集中的分布格局,景觀斑塊密度與邊緣密度較小,景觀異質性較低。越接近天然次生林區,景觀異質程度越大。
