| 摘 要： | 基于遗传算法对连续数据进行区间数的最优量化和区间的分点值计算,同时将各量化区间模糊化,对预处理后的数据利用粗糙集理论建立小区用地属性决策表,并进行属性约简,得出决定小区用地类型的决策规则.同时,分析计算了各条件属性对各用地类型的不同权重,克服了传统方法确定权重系数的主观性.

| Abstract: | On the basis of genetic algorithm the optimal quantization of interval numbers and the calculation division point value are conducted, at the same time the quantized intervals are fuzzified, in addition, according to the preprocessed data and using the fuzzy set theory the decision-making table for the small area land-use is constructed and its attributes are reduced, then the decision-making planning for the small area land-use is obtained. Meanwhile, different weight of each condition attribute correlated with land-use type is analyzed, so the subjectivity of traditional method in the determination of weight coefficients is overcome. |
