人口多、耕地少、耕地后备资源不足是我国的基本国情。但是随着我国经济的飞速发展,建设用地的数量不断增加,加强建设用地管理对于保护土地资源有着十分重要的意义。因此,就需要有一种专业性非常强的技术服务性工作,为建设用地的审批提供准确的面积、地类、权属和位置。这样就逐渐形成了建设用地勘测定界。 A large population, less cultivated land and insufficient cultivated land reserve resources are the basic national conditions in our country. However, with the rapid development of economy in our country, the quantity of construction land is increasing constantly. It is of great significance to strengthen the management of construction land for the protection of land resources. Therefore, there is a need for a highly professional and technical service work to provide an accurate area, land type, tenure and location for the approval of construction land. This gradually formed a construction land delimitation.
