摘要: 通过对小陇山林区党川林场二类调查数据进行统计分析,阐述了党川林场生态公益林的特点,并依据森林起源、树种(组)、立地类型和经营目的4个划分因子划分经营类型。结果表明:党川林场生态公益林以天然林居多,林种结构比较单一,主要为水源涵养林,尤以华山松、栎类、红桦、白桦等为优势种的林分较为突出,混交林单位面积蓄积明显高于针叶纯林和阔叶纯林;林龄结构不合理,中龄林和近熟林占主导;14种立地类型中“中山阴薄急险”、“中山阳薄急险”、“中山阳中急险”、“中山阴中斜陡”等的蓄积和面积比重较大,2 430个生态公益林小班可划分为29个经营类型。科学划分的经营类型可为小陇山林区生态公益林制定经营措施提供理论依据和重要参考。

Abstract: Through statistical analysis of forest resources inventory and planning data for Dangchuan Forest farm in Xiaolongshan forest area,this paper aimed to expound the non-commercial forest characteristics and classify management types according to the origin of the forest,tree species (groups),site types and management objectives.The results showed natural forest was in the majority,the forest category structure was relatively simple,it was mainly the water source conservation forest,especially the Pinus armandii,Quercus spp.,Betula albosinensis,Betula platyphylla forests,etc.The volume of per unit area for mixed forest was significantly higher than pure coniferous forest and pure broad-leaved forest.Forest age structure is unreasonable,middle-aged forest and nearmature forest were dominant.Four site types,such as middle geomorphology & shady slope & thinner soil layer & steep slope,had bigger volume and area proportion of non-commercial forests.2 430 subcompartments of non-commercial forest can be divided into 29 management types.This will provide theoretical basis and practical guidance to form complete management measures for non-commercial forest in Xiaolongshan.

Key words: Xiaolongshan, non-commercial forest, management type
