| 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15 hm2的样地,并在地形同样复杂的十万大山地区标定了多个1 hm2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。 |

| Abstract: |
| [Objective] Rugged karst or non-karst terrains prevail in south of China, and which may result relatively big measurement error when the general survey method applies to the terrains. In order to resolve this problem, we proposed a method that could be applied to forest plot survey in the rugged topography with steep slope.[Methods] The method was based on the setting out survey function of the total station. To make full use of the large number of exposed rock, the method improved the way of stake mark. Moreover, the method also improved the way of selecting control point and writing corresponding calculator program.[Results] By using the method, a 15 hm2 forest plot in the karst forest in Nonggang National Nature Reserve and several 1 hm2 forest plots in non-karst forest in Shiwandashan mountainous area were mapped successfully where terrains were complex with steep slope.[Conclusion] The practice results indicated that the method could be applied to the karst region or non-karst region with rugged topography, and got high precision even in mapping the big forest monitoring plot. |
