| 摘 要： | 土地复垦方案编制过程中,需计算各地类面积,搜集的资料如果仅有非矢量化线条版土地利用现状图,如纸版或jpg、Tif等图像文件,统计各地类图斑块面积手工描图工作量比较大,且精确度不能满足方案需要,常常成为土地复垦方案编制效率提高的制约因素,笔者根据多年从事计算机技术及工程绘图经验,总结并实践了利用像素点法计算不规则形状图斑面积的方法,供环评、土地复垦工作者参考.

| Abstract: | If data collection have just vectorless Land-use Map（eg. ＊.jpg,＊.tif or paper） in Land reclamation plan compiling process, there is the heavy workload to calculate patch area of Land-use Map. Calculation results do not comply with requirements. These restrict the working efficiency. This article describes pixels method of irregular shape patch as a reference for the eia worker, land reclamation workers. |
