| 摘 要： | 为了分析黑龙江省水资源在空间上的匹配情况,将黑龙江省划分为13个子区域,将水资源总量作为匹配原象,选取人口、耕地面积、第二产业总产值作为匹配对象,引入经济学中的洛伦茨曲线,并通过积分方法求解基尼系数,应用基尼系数分析水资源与人口、耕地资源和第二产业的匹配程度。结果表明,黑龙江省水资源与人口、耕地和第二产业总产值的空间匹配基尼系数分别为0.4606、0.4824和0.7184,匹配程度处于较差或极差水平;在未来水资源的优化配置过程中,应注意水资源空间匹配的合理性。

| Abstract: | Heilongjiang Province is divided into 13 sub-regions in order to analyze water spatial matching.According to the principle of Lorenz curve,the total of water resources is selected as the match of the original elephant and polulation,land,secondary industry output value are selected as the matching object.Gini coefficient which attained by integral method was used to analyze the matching degree of population,land,secondary industry with water resources.The result showed that Gini coefficient of population,land,secondary industry with water resources was respectively 0.4606,0.4824 and 0.7184.The matching degree was at poor or very poor level.Water spitial reasonable matching should be payed attention in the process of the optimal allocation of water resources in the future. |
