摘要
为了解决防护林类型选择技术问题，测定了洞庭湖水系内２４个主要防护林类型的生产力、林地土壤的渗透能力、水稳性指数、土壤最大蓄水能力、有效贮水能力及林分最大持水能力，并运用多级分辨等方法，对防护林类型的上述功能进行了判别分析，提出了１８个可供多种功能上选用的选择技术模型。选择技术模型回判结果。
The object of our study was aimed at seeking a series of techniques for selection of protection forests. Therefore the following functions were evaluated:productivity of the main protection forest, permeability capacity of the forest soil, water stablization index, maximum water storage petential of the soils, effective storage capacity and maximum water retainning potential of stands. Futhermore, a multi-step determination approach was utilized to determine the functions of the protection forests. On the base of this analysis, a total of 18 technique selection models were established for multi-function selection. The coincidence rate of these models determining the functions of forests with historical data were above 75.0%.
