The study of the effect of vegetation on snow ablation can be used to predict the snowline, glacier and water level. The snow ablation is observed in the Picea crassifolia, shrub, frost edge and grassland of sunny slope at the altitudes between 2600 and 2700m from 2003 to 2007. The daily variable of snow depth and the change of snow coverage and the sensible heat flux of snow surface are used to determine the snow ablation at Pailugou Basin of Water Conservation Forest in the Qilian Mountains. The observation began with the snowfall in October and ended at the completely ablation of snow in May, and got 1344000 observation data.

Firstly, according to study dynamic changes of the elements structures in succession about natural and artificial forest, then summarized regular patterns;at the same time.based on the study of Coupling Relationship between structure and function of water conservation forest established the ideal structures from the stand level and the watershed level. The ideal structures from the stand level: uneven-aged, double layer and mixed structure, and trend to natural forest. The watershed level followed the same principle, that is double layer patches, uneven-aged forest well-distributed and to build up different forest patches in watershed.
首先,经过对北京山区水源林天然林和人工林结构要素的演替动态研究,提出其发展规律,同时依据水源林结构与功能耦合关系研究,从林分层次和流域层次上分别构建了水源林的理想结构,其中,林分层次上水源林的理想结构为:异龄、复层、混交的结构状态,林分结构趋于天然林结构的特征;在流域层次上水源林的理想结构为也应形成&复层&、&异龄&、&混交&的结构,即:在流域各水源林斑块间形成林冠层复层、斑块内部乔木、灌木、草本层的复层;不同水源林年龄面积上的均匀分布;形成不同水源林斑块间的镶嵌分布。
