徂徕山刺槐萌生林更新改造实验初报

Experimental study on transformation of Robinia pseudoacacia coppice forest in Culai Mountain

徂徕山林场现有刺槐纯林1332.7hm2,为萌生一代林、二代林。针对刺槐连作使林地总体质量下降、林分退化、生态功能降低等特点,实施刺槐退化林分改造,提高林地利用率是当务之急。本文对徂徕山刺槐萌生林林分现状及退化原因进行调查分析,总结出改造方式及技术要点,为同类型地区刺槐萌生林分改造提供技术依据。

The area of the existing pure Robinia pseudoacacia forest in Culai Mountain Forest Farm is1332.7hm2,which is the first generation and the second generation of coppice forest.Because of the continuous cropping of Robinia pseudoacacia,the overall quality and the ecological function of forest land will decline.It is urgent to implement the transformation of Robinia pseudoacacia forest and improve the utilization rate of forest land.In this paper,the status and degeneration reasons of Robinia pseudoacacia coppice forest in Culai Mountain were investigated,and the transformation methods and technical points were summarized.This will provide technical basis for the transformation of Robinia pseudoacacia coppice forest in the same type area.
