分维值的大小与森林面积、斑块数量和平均斑块面积等项指标没有直接关系，而是三者有机结合的综合表现。

The quantity of fractal dimension has no direct relation with the forest patch and the average area of each patch , instead it is the comprehensive index of them .

景观水平计算分析表明：从1973-1990-2000年，整个研究区的斑块数增加、斑块密度逐步提高，而平均斑块面积在减小，这说明了斑块破碎化程度增加。

Landscape level analysis shows : from 1973 to 1990 and 1990 to 2000 , the number of patches increased and patches density gradually increased but the mean area of patches gradually decreased ;

选取了斑块数、平均斑块面积、斑块形状指数、破碎化指数、分维数、景观异质性指数和景观均匀度指数等指标进行研究分析。

Several targets , such as patch number , average patch area , form index of patch , fragmentation index , sub-dimension , heterogeneity index of landscape and homogeneity index of landscape were studied .

研究区域的景观斑块密度和边缘密度的分析结果表明，绿色空间破碎化程度沿梯度方向总体呈下降趋势，平均斑块面积逐渐变大。

Analysis on the patch and edge density of landscape showed that the degree of fragmentation of green space took on a downward trend along the gradient direction and the average patch area became gradually larger .

本文还从景观生态学的角度，对研究区内的两期数据进行景观多样性指数、景观优势度指数、景观破碎度指数、景观均匀度指数和平均斑块面积指数等进行景观指数评价。

To evaluation the wetland data of 1995 and 2005 by the view of landscape ecology by computing landscape diversity , landscape dominance index , landscape fragmentation index , landscape evenness index and even patch area index .

由此可以初步地认为平均斑块面积与面积损失值之间存在负相关，即平均斑块面积越大则精度损失值越小。（3）近20年期间宜兴市土地利用变化剧烈。

It can be preliminary view that the average size of loss and a negative correlation between the value and area ;( 3 ) The land-use change during of Yixing in the past 20 years is intense .

各景观类型的平均斑块面积和周长遵从分形规律，分形维数1.30，景观整体的斑块边界的褶皱程度较低。

A power law relationship was found among the mean patch areas and perimeters of all the landscape elements , with a fractal dimension of 1.30 , indicating a low degree of patch perimeter complexity in the landscape .

斑块数量、平均斑块面积、标准差、斑块总面积、最小斑块面积、最大斑块面积、极差、偏度、峰度、中位数、众数等统计量被用于描述海南岛植被景观的斑块大小特征；
