基于价值评价法的人工林下更新苗木优化选择研究

Optimization of Planted Seedling under Plantation in Beijing Based on Value Evaluation

在价值评价法的基础上对林下更新苗木所具有的综合价值设计方案进行评价。评价结果认为,在以生态公益林定位的森林经营中,人工林下更新幼苗的综合价值依次是栓皮栎、构树、黄栌、华北五角枫等,所以在林下层苗木的经营选择中应该按照这些树种的综合价值来进行苗木的选择和操作。除此之外,通过该实例给基层森林经营作业提供一个"物美价廉"的统筹经营的方法。

The concept and evaluation method of value evaluation（VE） and value analysis（VA） were intro- duce. The comprehensive value of the planted seedlings under forest in the designed scheme in Beijing were assessed by applying VE and VA methods. It was indicated that the value of the seedlings under ecological forests followed the order of Quercus variabilis , Broussonetia kazinoki , Cotinus coggygria , Acer truncaturn etc. It was concluded that in the forestry management, comprehensive values should be considered to select seedling species with high values for regeneration under forests. In addition, authors want to find an ＂effective and economical＂ overall planning management for grassroot levels.
