摘要
空间罗伦兹曲线在经济地理研究中具有非常广泛的应用,本文通过实例着重研究空间罗伦兹曲线集中化指数的几种计算方法。在这些方法中,十等分法和改进的十等分法所求得的集中化指数只能算估算值,存在一定的误差;而三角形法和梯形法所求得的集中化指数为精确值。通过研究可为集中化指数的计算提供更多的方法。
Space Lorentz curve is widely used in economic geography studies. This paper focus on several methods in the calculation of centralization index of space Lorentz curve. These methods include ten-part method ,improved ten-part method , triangle method and echelon method . The centralization index calculated by ten-part or improved ten-part method is just the estimating value which must has some error . The index got ,from the other two methods is accurate which can be better used.
