土地利用图缩编中小图斑综合方法的改进

Methods Improvement of Small Figure Spot Comprehensive in Land Use Map Downsizing

针对土地利用图缩编中小图斑综合方法存在的问题,提出了改进方法。引入数学模型使得最小上图图斑面积指标的确定具有针对性;同时将专家的知识和经验引入计算机制图,使得小图斑综合具有高效性和客观性。以太湖县二调成果1∶10万地形图制作为例,验证了该方法的可行性,具有一定的实用价值。

According to the question of the spot comprehensive in the current land use map downsizing,we put forward some improvement methods,which were introducing mathematical models to make the area index of minimum figure spot have pertinence,and introducing expert knowledge and experience to computer drawing to make comprehensive of small figure spot efficient and objective at the same time.Taking Taihu county's second land survey 1:100 000 map drawing for example,it certified the feasibility of these methods.These methods have a certain practical value.
