摘要: 在分析乔木水土保持林防护机理的基础上,通过对渭北黄土高原剌槐水土保持林调查、分析,确定该区剌槐水土保持林在常规密度下的初始防护成熟龄为11~16年(平均为12年);最大防护成熟龄为25年;更新龄为42年;防护成熟期(更新龄与初始防护成熟龄之差)为26~31年。以防护成熟龄为基础,确定剌槐水土保持林的三个经营阶段:成熟前期、防护成熟期和更新期。这些结果将为水土保持林的合理经营提供参考。

Abstract: On the basis of the discussion on protective maturity of water and soil conservation forest (WSCF),investigations on Robinia pseudoacacia WSCFin Weibei Loess Plateau were made.The investigation items included stem diameter,tree height,crown,structure,stem analysis,soil,site condition and so on.Total 80 sample plots were obtained.Based on the investigation data,initial protective maturity age (IPMA),maximum age of protective maturity (PMAmax),regeneration age (RA) and protective maturity period (PMP) of R.pseudoacacia WSCF were determined.In the case of normal density (initial stem density =2 m×2 m,the preserved rate =80%) of Robina pseudoacacia WSCF,the results were as follows: IPMA=11~16 years,PMAmax=25 years,RA =42 years and PMP=26~31 years.Three phases for management of WSCFwere divided according to protective maturity ages.These results may provide some references in management of R.pseudoacacia WSCF.
