| 摘 要： | 耕地资源的集约利用关系到国家的粮食安全和社会的稳定.以2009年黑龙江省耕地利用状况为研究对象,采用熵值法分析计算黑龙江省耕地集约利用的区域差异及影响因素.结果表明,2009黑龙江省耕地集约度平均水平为0.1417,集约利用水平较低;各县市耕地集约利用水平存在较大差异,各县市耕地利用集约度空间自相关指数Moran'I为0.14,县域间耕地集约利用水平具有显著的空间自相关性和集聚特征;耕地利用集约度高区域主要集中在主要地级市(包括加格达奇区)及其周边县市,三江平原以及松嫩平原的南部和东部;黑龙江省耕地集约利用空间分异主要受区位条件、自然特征和经济状况等因素的影响

| Abstract: | The cultivated land resource intensive use is the key to the national food security and social stability.This paper,taking cultivated land use status of Heilongjiang Province in 2009 as research object,used the method of entropy to analyze the regional differences and the influencing factors.The results showed that the average degree of cultivated land intensive use was 0.1417,low in it’s level;the cultivated land intensive use level was difference among the regions,the Moran’I was 0.14,and it showed that the cultivated land intensive use level had significant correlation and gathering since the space characteristics;the high level was mainly concentrated in the main cities(including Jiagedalqi)includring the surrounding counties,the south and the east of Sanjiang Plain and Songnen Plain;the main factors for the regional differences were regional conditions,natural characteristics,and the state of the economy. |
