地形破碎地区土地面积量算方法的比较分析——以黄土高原为例

Comparing and Analysing of the Methods of Measuring Land Area in the Broken Terrain Region——The Example of the Loess Plateau

选择了当前有代表性的6种面积量算方法,对地形破碎实验区分别进行量算和综合分析,认为运用计算机系统,不仅量算精度高且速度快,在目前计算机技术尚未广泛普及的情况下,对于小区域的量算工作,称重法、方格模片法和网点模片法亦不失为有效方法。

In this paper, six kinds of area measure methods are chosen and the broken terrain experimental region are measured. On the bases of analysing experimental results, think that computer system have higher precision and faster speed. But when computer system can't be spread at present, weight method, check and net mould plate method are effective methods of measuring the area of small region in the broken terrain region.
