As the surface altitude increases, the water level and the imbedded water level decrease, and is lowest in Betula ovilifolia－Carex schmidtii－Sphagnum palustre community, which may be firstly caused by the distribution of the hummocks of Sphagnum palustre, which is powerful in holding water, and this has cushion function on the change of water level; On the other hand, it may be caused by it's position near the hill, the runoff from the hill may supply the district, so that the change extent of water level at a certain extent minishes.

随着地表相对高程的增加，水位变化幅度逐渐变小，在油桦－臌囊苔草群落中最小，这一方面可能与泥炭藓丘的分布有关，泥炭藓具有较强的饱水和持水能力，对水位的变化具有一定的缓冲作用；另一方面是由于该区靠近山地，山坡上形成的坡面径流可能对该区域有所补给，这也在一定程度上减小了水位的变化幅度。
