The West Liaohe River Basin is one of the key areas to explore the origin of dry agriculture in China. From the Neolithic Age to the Bronze Age, the West Liaohe River Basin has a relatively complete sequence of archaeological culture. In the first site of Xinglonggou Site of Xinglongwa culture, the earliest carbonized broomcorn species were found, which advanced the origin of dry farming in the West Liaohe River basin to 8000 years ago. From the period of Zhaobaogou culture to the period of Hongshan culture, dry farming developed steadily and gradually occupied an important position in subsistence. During the Xia Jiadian lower culture period of the early Bronze Age, the dry farming in the West Liaohe River basin took a leap forward, and the content of carbonized millet and broomcorn found was greatly increased compared with that before. The reasons for this leap are various, such as changes in the natural ecological environment and population settlement factors. At the same time, the rapid development of dry farming greatly promoted the progress of production tools and social development at that time. In addition, the dry farming in the West Liaohe River basin spread to Northeast Asia, Central Asia and Southeast Asia, which had a great impact on the local agricultural development.
西辽河流域是探索中国旱作农业起源的关键地区之一。从新石器时代至青铜时代，西辽河流域有着较为完整的考古学文化序列。最早在兴隆洼文化的兴隆沟遗址第一地点的考古发掘中，发现了距今年代最早的炭化黍种，将西辽河流域旱作农业的起源提早至距今8000年。从赵宝沟文化时期至红山文化时期，旱作农业稳步发展并逐渐占据生业中的重要地位。发展至青铜时代早期的夏家店下层文化时期，西辽河流域的旱作农业发生了飞跃，发现的炭化粟、黍的含量相较之前有了极大的提升。出现这种飞跃的原因是多样的，如自然生态环境的变化、人口聚落因素等。同时，旱作农业的快速发展在很大程度上促进了当时生产工具的进步以及社会的发展。除此之外，西辽河流域的旱作农业传播至东北亚、中亚及东南亚的部分地区，对当地的农业发展起到了十分巨大的影响.
