南方集体林地的林权比较复杂,属公社、大队、生产队、户的都有,还有各种类型插花山。且由于人为活动频繁,林相不整齐。若以分层抽样调查,往往不能适应需要。因此,有些省份采用小班目测与实测进行回归,将资源落实到小班,收到较好效果。现将其方法介绍如下。 The forest rights of the collective forests in the south are rather complicated. They are communes, brigades, production teams and households, as well as various types of flower-blossom hills. Due to frequent human activities, the forest is irregular.
