岷江上游干旱半干旱河谷区生境质量评价——以杂谷脑河为例

Evaluation on Habitat Quality in Arid and Semi-arid Valley Area 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9个因子对该区域的生境质量进行了评价,并根据评价结果提出了合适的造林措施和对策,为该区域的造林树种选择和配置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。

Selecting the Zagunao River arid valley area in the upper reaches of the Minjiang River valley as the research object, using the data of field investigation, combined with investigation subcompartment data of forest resources and forest land use data protection, and based on factors such as the topography, soil, water, vegetation and so on, nine factors of habitat quality were evaluated in the region, and afforesta- tion measures and countermeasures were put forward according to the evaluation results, aiming to provide scientific basis and theoretical guidance for the area of afforestation tree species selection and configura- tion model, but also for the similar difficult site conditions in artificial vegetation restoration.
