摘要: 本文以昆明西山滇青冈为优势的亚热带常绿阔叶林为对象,介绍并比较了三种植被调查方法,即无样地取样法的中点象限法、记数样方法和样地记录法。按样地数目的代表性,采用6线90中点分别与两组3个400m2样地作比较。在各工作小组的人数和熟练程度基本一致条件下,记录完成时间,以对比速度。内业工作量也作了比较。从深入比较中清楚看到,对于亚热带常绿阔叶林的调查,中点象限法并不是一种可取的方法。

Abstract: Three methods of vegetation surveying: the point-centered quarter method, counted quadrat method and releve method were used in the investigation of the subtropical evergreen-broadleaved forest of Westhill Kunming. The forest is dominated by Cyclobalanopsis glaucoides. Six sampling lines each with 15 center points were taken to compare with three 400m2 plots of two sets. Workmen are divided into 6 groups, each with the same number and similar skill level. The time taken by each group for accomplishing their work must be recorded so that the speed can be compared. We also compared the amount of work and speed of each group indoor. From this kind of comparison, we arrived at a conclusion that the point-centered quarter method is not a desirable one, at least in investigating subtropical evergreen-broadleaved forest.
