The provided is a construction method for a flood storage area ecological wetland oriented to multi-target collaborative promotion. The construction method includes: I. carrying out ecological wetland construction on a flood storage area by taking promotion of agricultural production as a goal; II. according to a water purification target of the flood storage area of the ecological wetland and a current pollution condition in the flood storage area, constructing the ecological wetland based on improvement of the water purification target when the flood storage area does not reach the water purification target at present; and III, in order to improve the biodiversity, carrying out the following ecological wetland construction on the flood storage area. In the method, agricultural production, water purification and biodiversity improvement of the flood storage area are comprehensively considered. The method is the most effective way for multi-target collaborative promotion of the flood storage area.

A technique has been developed to fabricate micro- or nanopumps based on porous alumina thin films. The main body of the nanopump consists of a porous alumina thin film (containing nano-sized channels of about 40-300 nm in diameter) with conductive surfaces (e.g. Au coating layers) on both sides of the film. Through the fabrication of nanochannels in (the alumina films) and the subsequent annealing and surface activation processes, high-efficiency micro- or nanopumps can be made. The nanofluidic flow through the nanochannels of the alumina thin films is driven by an electric field with no moving parts. The flow rate (up to 50 millilitres/(min&#xb7;cm)) of water through the alumina thin film can be continuously tuned through the intensity of the electric field, i.e., the DC electric potential applied across the nanochannels.
