Study On The Constructed Landscape Mode Of The Artificial Wetlands Ecological System

The artificial wetland landscape system is a special system which is constructed on the base of artificial wetland system and landscape system, is composed by the essential factors of landscape, such as construction, plant, water body, biological community, architectural environment art sketch and so on, having dual effects of purification and beautification, is one of the city, community landscape. The artificial wetland landscape system can alleviate the running pressure of the traditional water landscape (including Shore water landscapes ,near lake landscape, near mountain stream landscape, artificial lake landscape and so on water landscape), such as high running cost, the maintenance difficulty and so on , and can controls the eutrophication, safeguarding the water quality.According to previous research results, this article summarized that the artificial wetland processing technology has low investing, good effect, strong anti-impulse ability, simple operation, low maintenance and operation cost and so on; at the same time, by planting hydrophyte and pisciculture, green and beautify the environment, increase the green area, rich visual landscape non-uniformity. Therefore, the artificial wetland system which has purifying and landscape dual responsibility been introduced into the landscape design, can fully exert artificial wetland purification function and esthetics function, build the landscape system with ecology, ornamental, multiplicity, efficiency.According to the research of conducts to the artificial wetland system structural properties and the landscape characteristic, this article analyzed the artificial wetland system and the landscape system have the biggest fusion spot——lies in the plant and the water body ,the plant and the water body all are the artificial wetland system and the landscape system essential factor, therefore, based on the display artificial wetland ecology function angle, by the water body, the plant essential factor primarily, disposes the corresponding other landscape essential factor, ingeniously fuses the artificial wetland system and the landscape system, carries on the artificial wetland the overall landscape plan design, builds has the purification, the beautified function, has efficiency, sustainable the water landscape system.According to water source characteristic, region in moisture content for rain water, sanitary sewage and big area waters. When artificial wetland landscape system plan design, first determined processes the water body the characteristic, and analyzes the water body the water quality characteristic and the water volume; Then According to basis result, choices suitable artificial wetland unit type and occupying a land area of scale; Finally, connects the artificial wetland unit through the ways of use natural rill, running water sculpture, waterfall, pipeline and so on, it forms the integrity the ecosystem, and builds has the ecology naturally, the unification, the multiple landscape system. When plant disposition, according to plant's purification function and aquatic plant's root, the stem, the leaf displays the color, the shape, the sense of reality difference, uses the different disposition technique, forms the multiplicity, the multi-level plant community. Then in the artificial wetland landscape system design idea, the union initial form landform condition, take full advantage of terrain conditions, reduces excavates the quantity, causes the system everywhere manifests"ecological"in the construction and the movement process.
