摘要: 【目的】为了提高优树选择效率,减轻野外工作难度,探索新的优树选择方法。【方法】以我国黑龙江省孟家岗林场的长白落叶松人工林为选优林分,采用优势木对比法、小标准地法和基于遥感技术法3种不同方法进行优树选择,并对3种选优方法从增益、时间和人力等方面进行了综合比较。【结果】每种方法分别选出候选优树45株,以材积大于群体平均值250%为标准最终确定入选优树6株。基于遥感技术的选优方法优势明显,可以有效地弥补传统优树选择范围有限、费力费时的不足,从而节省大量的人力物力和时间,显著提高优树选择效率。【结论】遥感技术与传统选优方法相结合的创新性尝试可为发展高效的优树选择方法提供新的视角。

Abstract: 【Objective】 In order to improve the efficiency of selecting excellent trees and reduce the difficulty of field work,and exploring new ways to select the plus tree. 【Method】 This study is based on the selection of Larix olgensis plantations in Mengjiagang forest farm of Heilongjiang province,China. The dominant tree comparative method, the plot method and the selection based on remote sensing data,totally three different methods are used to select the plus trees. Those three methods were comprehensively compared from gain,time and man power cost. 【Result】 For each method,45 candidate superior trees were selected,and 6 trees were selected for the better than the group gain of more than 250%. The selection method based on remote sensing technology has obvious advantages. The advantages of remote sensing technology can effectively make up for the shortages of traditional plus trees selection methods,which is laborious and time-consuming,thus saving a lot of manpower, material and time,and significantly improving the efficiency of plus tree selecting. 【Conclusion】 Innovative attempts to combine remote sensing technology with traditional selection methods will provide a new perspective for developing efficient ways for plus tree selection.

Key words: Larix olgensis, remote sensing technology, plus tree selection, method comparison
