摘　　要：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 discussed.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 isotopes 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 C4 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 axetyped tools proved that dry farming was already quite mature in the late Erlitou period.
