　　用寺河南、二里头、新砦等新石器晚期遗址的环境指标，讨论了豫西地区的史前（4．2～3．5 kaBP）农业生产环境．寺河南遗址地层孢粉组合指标显示，该区龙山文化晚期气候暖湿，除粟作农业外还有一定的稻作农业生产；进入二里头时期气候趋于干旱，旱作农业快速发展．新砦、二里头遗址出土的动物骨骼 C、N 同位素数据表明，两个时期人们的食谱主要是 C4类作物，畜牧业的进步表现在二里头时期肉食比例高于龙山时期．同时镰刀类工具代替斧铲类工具的事实表明，二里头晚期旱作农业已经相当成熟．

With the environmental indicators of the late Neolithic sites of Sihe ’nan Site, Erlitou Site and Xinzhai Site,prehistoric (4.2 ~3.5 kaBP) agricultural production environment in the west area of Henan province was dis -cussed.Bordered in the Cooling events in 4 kaBP, the area was warm and wet climate in late Longshan Culture stage , in addition to millet agriculture but also have some rice agriculture production .In the Erlitou cultural period, however, the climate became dry and cool, while dry farming made a rapid development .According to the carbon and nitrogen i -sotopes data of the animal bones unearthed in the Erlitou and Xinzhai Sites , it was suggested that the diet of people in both periods was mainly with C 4 crops, the progress of animal husbandry reflected in proportion of meat -intake in the Erlitou period was higher than Longshan period .At the same time,the fact of the sickle-typed tools replacing of axe-typed tools proved that dry farming was already quite mature in the late Erlitou period .
