面积量算的方法较多,但在基层应用较广的是方格法。方格法有量算精度较高,简单易行的优点。其缺点是花工量大,在记数过程中因漏数或重数发生差错,使量算误差增大。为了克服方格记数法中的差错,我们将方格法的量算过程稍加改进,总结出“座标小格逐一平差法”。这一改进方法有“似慢实怏,准而不乱,小格一次平差”的优点。现将作法介绍如下一、方法步骤1、将图用透明方格纸描下(如下图); 2、在方格纸上按每厘米距离编上纵横座标号; 3、列出方格座标记数表; 4、按座标系,从1—1’格数起,直到最后 There are more ways to measure the area, but the more widely used is grass-roots grid method. The checkered method has the advantages of high accuracy and easy calculation. The disadvantage is the large amount of flower workers, due to errors in the number of missed or heavy count in the counting process, so that the amount of error increases. In order to overcome the error in the grid counting method, we will slightly improve the calculation of the square method, summed up the “coordinate small grid one by one adjustment method.” This method of improvement has the merit of “being as slow as possible, accurate and not chaotic, and once a small grid is adjusted.” Now the practice is introduced as follows First, the method steps 1, the figure with transparent grid paper description (as shown below); 2, on the grid paper per centimeter distance on the vertical and horizontal seat number; 3, Number table; 4, according to the coordinate system, from 1-1 ’grid until the last
