为了提高森林资源调查效率,改进调查方法,1975年我们在广西大苗山区的融水县四荣公社开展资源清查的同时,对七株木模拟样地抽样法进行了试验。试验结果表明:这种方法简便易行,效率较高,精度可以满足要求;并且操作时无须使用测量仪器,因此为开展群众性资源清查工作提供了有利条件。对于地形复杂,山高坡陡采用方形样地有一定困难的南方林区,可能是种可取的方法。一、试验区简况试验区位于广西桂北林区的西北部,融江支流一贝江两岸,属大苗山区;平均海拔600
In order to improve the efficiency of forest resources investigation and improve the survey methods, in 1975, we carried out resource inventorying in S Rong Village, Rongsan County, Guangxi Zhuang Autonomous Region. The test results show that this method is simple and easy to operate with high efficiency and accuracy to meet the requirements. And it is unnecessary to use measuring instruments during operation, which provides favorable conditions for carrying out mass resource inventory. For the complex terrain, the use of steep slopes of square plots have some difficulties in the southern forest, may be desirable species. A Brief Introduction to the Experimental Zone The experimental zone is located in the northwestern part of Guilin, Guangxi. The tributary of the Rongjiang River is a large mountainous area with an average altitude of 600
