岷江上游干旱半干旱河谷区生境分类研究——以杂谷脑河为例

Research on Habitat Classification in Arid and Semi-arid Valley Areas of the Upper Reaches of the Minjiang River—Using the Zagunao River as an Example

以岷江上游杂谷脑干旱河谷区作为研究对象,利用实地调查资料,结合森林资源二类调查小班数据和林地保护利用资料,根据地形、土壤、水分、植被等因子对该区域河谷地带、阴坡和阳坡的生境分别进行了分类,为该区域的生境质量评价提供依据,也为人工造林中树种选择及造林模式提供科学依据和理论指导,同时也为类似困难立地条件地区的人工植被恢复提供参考依据。

In this paper, selecting the Zagunao River arid valley areas in the upper reaches of the Minjiang River as the research object, using the data of field investigation, combined with investigation subcompart- ment data of forest resources and forest land use data protection, and based on factors such as topography, soil, water, vegetation in the region river valley, slope and slope of habitat, respectively, the classification work was done in order to provide the basis for the area of habitat quality evaluation, as well as artificial afforestation tree species selection and afforestation patterns, and a scientific basis and theoretical guid- ance. Besides, this work but also provided reference for artificial vegetation restoration in the similar diffi- cult site conditions.
