三、土地利用现状评价与分区
一,方法一:
评价系数法
先把不同量纲评价指标以全县指标为平均值进行标准化处理~把不同量纲的指标化为无量纲系数~经过系数加总得出总评价系数。
评价系数计算公式为:
XijP,ijXj式中:
P——第j项指标的评价系数,ij
X——第j项指标数值,ij
X——第j项指标的平均值,本例以规划县全县各指标的平均值,。

应用上述公式~逐项计算各项指标的评价系数~分别确定各项指标的权重W~最终求出i
加权评价系数总和?
PW~对土地利用现状进行综合评价。

二,方法二:
直接聚类法
1、聚类指标的选择
2、聚类要素的数据处理
1,总和标准化
xi,(),iXn
i,1Xi,2,极大值标准化
xi,()X,ixmax
3,极差标准化
xi,()X,ixx,maxmin
3、聚类统计量的选取与计算
1,相似系数
n
x,x,ikjk,1k,cos,ijnn22x,xikjk,,,,11kk
i和j代表两个地点~xik、xjk表示两个地点的第k个特征值或指标。
2,相关系数
n
(x,x)(x,x),ikijkj,1kr,ijnn22(x,x),(x,x),,ikijkj,,11kk
xik、和xjk分别代表第i地点和第j个地点的第k个地理指标值。
3,距离系数
n
绝对值距离:
d,x,x(i,j,1,2,...,m),ijikjk,1k
n2d,(x,x)(i,j,1,2,...,m)欧氏距离:

在分区的基础上~形成相关分区图件。
成果为分值表、总分级图、三要素的层图及栅格图。
1、在各乡镇属性表中建立“土地开发利用程度”、“土地集约经营程度”、“土地利用
综合效益”、“综合分级”字段~数值型~并赋等级。
2、根据所赋的等级字段值分成三个等级~图形呈现。
