洞庭湖区防浪林林分林冠结构的研究

Study on the forest stand and canopy construction of wavebreak forest in Dongting Lake area

对洞庭湖区河洲、滩地上的不同林龄的旱柳、杨树防浪林、芦苇林进行了标准地调查,选取标准株(地),对其茎杆、枝条、叶片的空间分布进行了测定,通过对其差异进行比较分析,旨在间接测定不同防浪林的防浪效益的差异。

The investigation was based on different ages of Salix matsudana K. and Populus sp. wavebreak forest, Phragmitas communis T. and Miscanthus sacchariflorus m. sample plot in river continent and beach of Dongting Lake area. The stem pole, branch, leaf blade＇ s spatial of plants in the sample plot was tested and the difference were analyzed comparatively. The difference of wavebreak ben- efits of different wavebreak forest were tested based on the research results of sample plot＇ s plants.
