摘 要:公元前8世纪之前,中国农业产业分布分散,总体上呈均匀分布状态,基本上没有产业集聚。至公元12世纪,农业产业集聚开始得到发展,但直到1840年,农业产业集聚程度还很低,且农业产业布局呈小面状分布特点。至1949年,虽然农业产业集聚度仍不高,但农业产业布局开始呈现出典型的面状分布特点。到1980年,农业产业集聚程度进一步提高,农业产业布局仍呈现出典型的面状分布特点。1981年以来,农业产业集聚发展迅速,农业产业也开始出现与其他产业融合发展的趋势,虽然在一些经济发达地区农业产业开始出现一些分散倾向,但农业产业集聚仍是主流,面状分布的农业产业布局特点没有根本改变。The eighth century BC,agricultural industry was dispersed,the overall trend of distribution was uniform,and there was basically no industrial agglomeration.To twelfth century,agricultural industrial cluster development begun,and until 1840,the agricultural industry cluster degree was still very low,but the agricultural industry layout had the characteristics of small shape distribution.To 1949,the agricultural industry concentration degree was not high,but the agricultural industry layout began to show the characteristics of typical areal distribution.To 1980,agricultural industry cluster degree rose further,but agricultural industry layout was still showing the same characteristic.Since 1981,the rapid development of agricultural industrial cluster,agricultural industry also has begun to appear with other industrial development trend.In some developed areas agricultural industry has begun to have some tendency to disperse,but agricultural industry cluster was still the mainstream,and planar distribution of agricultural industry layout features did not change at all.
