摘要
为了分析水资源的空间匹配状况,根据区域用水结构及水资源空间分布与耕地、人口和第2产业分布的关系,以基尼系数和洛伦兹曲线为理论基础构建水资源空间匹配模型。运用该模型对重庆市水资源进行实例分析,结果表明:重庆市水资源与耕地面积的基尼系数为0.392 6,处于比较合理的水平;水资源与人口数量的基尼系数为0.533 4,水资源与第2产业产值的基尼系数为0.709 4,均处于高度不平均的水平,匹配状况极差。在结果分析的基础上,提出了提升重庆市水资源空间匹配度的对策。最后对该模型的适应性和有效性进行了讨论。
In order to analyze spatial matching of water resources,water resources spatial matching model is established.The model is established according to the structure of regional water use and the spatially distributing correlation between arable land,population and the second industry,and based on Gini coefficient and Lorenz curve.A demonstration applies to Chongqing.The results show that：Gini coefficient of water resources and arable land is 0.3926,and the matching degree is at a relatively reasonable level.Gini coefficient of water resources and population is 0.5344,and Gini coefficient of water resources and the second industry is 0.7094,and the matching degrees are at a very poor level.And then some countermeasures that help improve its spatial matching degree are offered.Finally,some discussions are carried out concerning the adaptability and validity of the model.
