在区域地理学中,心地(haartland)概念是借用政治地理学的心脏地区(The heartlard)或称枢纽区域(Pivotal area)概念,并加以发展而成的。心地概念在区域地理学中,除了政治含义以外,还被赋予了经济、文化等方面的含义。这一地理概念,在加拿大是指五大湖和沿圣劳伦斯河之间的中间低地,为加拿大的“心脏”——躯干的中心和最具活力的器官。在心地内,存在着地域和功能的综合。这一小区域是加拿大的人口和工业中心。 In regional geography, the concept of “haartland” is borrowed from the concept of “the heartlard” or “Pivotal area” of political geography. The concept of mind in regional geography, in addition to political implications, has also been given economic, cultural and other aspects. This geographical concept, in Canada, refers to the Great Lakes and the middle lowland along the St. Lawrence River, the heart of Canada - the center of the trunk and the most vital organs. In the heart, there is a combination of regions and functions. This small area is Canada’s population and industrial center.
