Terraced field type biological ditch wetland hydro-fluctuation belt treatment method based on seed bank
The invention discloses a terrace type biological ditch wetland hydro-fluctuation belt treatment method based on a seed bank, and relates to the field of wetland hydro-fluctuation belt remediation. The specific method is as follows: a hydro-fluctuation belt is transformed into a terrace type structure, the terrace type structure is provided with three different remediation treatment layers according to the water level, each remediation treatment layer corresponds to a step, a long ditch is arranged on the step, different seed banks are placed on each step; the gradient of the upstream face of the hydro-fluctuation belt is larger than or equal to 70 degrees. According to the method, a seed bank technology and a terrace wetland are combined, the hydro-fluctuation belt is subjected to terrace type microtopography transformation, the long ditch is pulled out on the terrace type topography at different water levels through an adaptive vegetation seed bank technology, biological ditches are formed at different water levels, dry branches and fallen leaves on the bank are carried by surface runoff to be flushed into the biological ditches, different vegetation can grow on the revetment along with the change of the water level when the plant seed bank is translated at the same elevation.
本发明公开了基于种子库的梯田式生物沟湿地消落带治理方法，涉及湿地消落带修复领域，具体方法为：将消落带改造成梯田式结构，所述梯田式结构按照水位设置有3个不同修复治理层，每一修复治理层对应一级阶梯，在阶梯上设置长沟，每一级阶梯上放置有不同的种子库；所述消落带的迎水面坡度≥70°。本发明将种子库技术和梯田湿地相结合，将消落带进行梯田式微地形改造，不同水位时，适应的植被种子库技术，在梯田式的地形上拉出长沟，在不同水位时形成生物沟，岸上的枯枝落叶携带经地表径流冲刷至生物沟内，平移的同一高程植物种子库，随着水位的变化，将在驳岸上生长不同的植被。
