Based on the output value of agriculture forestry,animal husbandry and fishery of each city（zone）in Hainan from 2000 to 2009,the concept of Lorrenze curves and Gini coefficierts（GC）were used to analyze the structure of the Value.The result indicated that the most unbalanced was the output value of forestry（GC=0.52）,and the second unbal anced was the output value of fishery（GC=0.45）.The output value of agriculture（GC=0.17）and animal husbandry（GC= 0.23）were more balanced.With time,the distribution of farming has no change,while that of the forestry and animal hus bandry and fishery exhibited an opposite trend.This demonstrated that the spatial and temporal distribution of output val ue in city（zone）of Hainan was unbalanced.This result can be helpful for structural optimization and regional intensive development of the Value.%基于海南省各县市（地区）2000-2009年农林牧渔业产值的数据,应用经济学中的洛伦茨曲线及基尼系数的理论进行了海南省农林牧渔业产值结构的定量化研究.结果表明：在空间尺度上,林业产值（2009年的基尼系数为0.52,下同）最不均衡,渔业产值（0.45）分布较不均衡,农业产值（0.17）和牧业产值（0.23）分布相对均衡;在时间尺度上,农业产值分布没有变化,而林业产值,牧业产值和渔业产值均有不同程度的集中.这反应出海南省各县市（地区）农林牧渔业产值空间分布及其时间变化均具有不同程度的非均衡性.该结论可为农林牧渔业产业的结构优化和区域集约化发展提供参考.
