Usually , polygon - partition was accomplished by drawing a random partition - line on the partitioned polygon unit by hand , while the rational analysis of essential requirements of prime farmland protection was ignored . so the polygon - partition was always arbitrary and random and could not meet the demand of orientation . on the other hand , the completion of polygon - partition usually relays on polygon - partition model of gis which was selected by hand , so mapping automatically was not achieved 通常的图斑定积分割仅是人工在需定积分割的图斑上任意输入一条分割线进行分割,在此之前缺乏对分割线方向的判断、选择决策,主观性和随意性较强,缺乏对基本农田保护区划定内在要求的合理分析,容易导致分割划入的基本农田只是在数量上满足要求,而不能满足定位需要;同时,图斑定积分割的最终实现一般都是由人工手动调用gis中的分割模块进行,准确率低、费时长,没有实现真正意义上的成图自动化。
