This superior nature surrounding is conducive to the early human existence and to the gash of ageiculture and animal husbandry. Therefore, since the beginning of the New Stone age, the primitive farming and animal husbands stared. UP till the time of the Western Zhou Dynasty and the Spring and Autumn Period, with the prominent rising of Qin people, the economic development pattern of semi-agriculture and semi-animal husbandry had taken shape.

从第四纪以来,陇中黄土高原的自然环境根据古土壤、孢粉、考古材料和文献记载考察,虽发生过若干变化,但总体上远较目前优越,无论气温、降水还是地带性植被状况都是较为优越的。当时,人类对自然的影响微乎其微,这种自然面貌反映了当地原始的自然环境状况。这种较为优越的自然环境非常适宜于早期人类的生存和农牧经济的发展,因而,从新石器时代开始,当地原始农牧业也就产生了。至西周春秋时期,伴随秦人的崛起,当地半农半牧的经济开发模式即已形成。
