摘　　要：【目的】中国南方存在很多地形复杂的喀斯特和非喀斯特区域,在这些地形陡峭的区域进行森林监测样地测量标定时,一般容易出现测量误差较大和一般测量方法适用性不佳的问题。为此,本研究提出一种适用于复杂地形的森林样地测量标定方法。【方法】以全站仪放样测量为基础,充分利用复杂地形中一般岩石出露较多的特点,改进定桩点标记方法,同时改进制点的选择方法并编制相应的计算器程序。【结果】利用该方法,成功地在地形复杂的弄岗国家级自然保护区的喀斯特森林标定了1个15hm^2的样地,并在地形同样复杂的十万大山地区标定了多个1hm^2的森林样地。【结论】本方法适用于地形陡峭复杂的喀斯特地区和非喀斯特地区,在测量大型森林监测样地时,具有较高的精度。【Objective】R ugged k arst or n o n-k arst terrains prevail in south of C hina,and whichm ay result relatively big m easurem ent error w hen the general survey m ethod applies to the te rrains.In order to resolve this p ro b lem,w e proposed a m ethod th a t could be applied to forestplot survey in the rugged topography w ith steep slo p e.【M ethods】T he m ethod w as based on thesetting out survey function of the total station.T o m ake full use of the large num ber of exposedro ck?the m ethod im proved the w ay of stake m ark.M oreover,the m ethod also im provedthe w ay of selecting control point and w riting corresponding calculator p ro g ram.【Results】By usingthe m ethoda15hm2forest plot in the k arst forest in N onggang N ational N ature Reserveand several1hm2forest plots in n o n-k a rst forest in Shiw andashan m ountainous area w erem apped successfully w here terrains w erecom plex w ith steep s lo p e.【Conclusion】T hepractice results indicated th a t the m ethod couldbe applied to the k arst region or non-karst regionw ith rugged topography,and got high precisioneven in m apping the big forest m onitoring plot.
