On the aspect of urban spatial distribution DM: Adopting the conception model of combination of location and attribute, the author brings spatial coordinates, spatial relationship and attribute character into the unitive model of spatial computation, studies city's land suitableness evaluation and the method of spatial clustering in division of urban function districts and brings forward the arithmetic of classification layer. Aiming at land spatial optimization allocation, the author puts forward SGA. In this arithmetic selection, crossover and mutation operator are progressed on the space.

They called it "infection of the germ", a neat instance of a modern sounding phrase with an obsolete meaning: the fetus permanently affecting the mother's reserve eggs. this idea was given its impressive greek name, telegony ("at a distance"and "offspring") by august weismann (1834–1914), the german biologist whose rigorous separation of somatic and germinal cells cast doubt on the inheritance of acquired characteristics. weismann believed his notion of the germ plasm could explain telegony, should it be shown to exist, but he doubted its reality.
他们称之为"细菌感染",意思是"胎儿永久影响母亲的储备卵子"。august weismann(1834年~1914年,德国生物学家)给这一理论起了一个令人印象深刻的希腊名字, telegony ("距离"和"后代"),他仔细的分离肉体和生发细胞,对特征遗传提出质疑。weismann相信他的关于遗传物质的概念可以解释telegony,它可能是真的,但weismann怀疑其真实性。
