摘　　要：通过构建农业水土资源匹配测算模型以及区域基尼曲线,计算了松嫩—三江平原地区的水土资源匹配系数和水资源—耕地资源基尼系数,对区域的水土资源匹配程度进行了划分。结果表明:松嫩—三江平原水土资源匹配系数、水资源-耕地资源基尼系数分别为0.381 04 m3/hm2、0.445 8,水土资源匹配较不均衡;水土资源匹配程度空间差异性较为显著,粮食主产区松嫩—三江平原中部的四平—长春—松原—哈尔滨—绥化—齐齐哈尔一线及三江平原腹地佳木斯一带水土资源匹配程度较差甚至极差。在未来水土资源的优化配置中,应注意作物种植结构的调控以及水资源空间匹配的合理性。By constructing the matching calculation model and regional Gini curve,the matching coefficient and Gini coefficient of regional land and water resources in Songnen and Sanjiang Plain were calculated,and the matching degree of the regional land and water was divided. The results showed that the matching coefficient and Gine coefficient of the land and water resources in Songnen and Sanjiang Plain was 0.381 04 m3/hm2 and 0.445 8,respectively,and not balanced. It showed significant spatial difference.The land and water resources matching degree was poor and even very poor in the main grain producing area in the middle of Songnen and Sanjiang Plain. The regulation of crop planting structure and the rational of spatial matching of water resources should be pay attention in the optimal allocation of land and water resources in Songnen and Sanjiang Plainn in the future.
